GROUND-WATER RESOURCES OF THE RIVERTON IRRIGATION PROJECT AREA, WYOMING

By D. A. MORRIS, 0. M. HACKETT, K. E. VANLIER, and E. A. MOULDER

ABSTRACT

The Riverton irrigation project area is in the northwestern part of the Wind River basin in west-central Wyoming. Because the annual precipitation is only about 9 inches, agriculture, which is the principal occupation in the area, is dependent upon irrigation. Irrigation by surface-water diversion was begun in 1906; water is now supplied to 77,716 acres and irrigation has been proposed for an additional 31,344 acres.

This study of the geology and ground-water resources of the Riverton irri gation project, of adjacent irrigated land, and of nearby land proposed for irrigation was begun during the summer of 1948 and was completed in 1951. The purpose of the investigation was to evaluate the ground-water resources of the area and to study the factors that should be considered in the solution of drainage and erosional problems within the area.

The Riverton irrigation project area is characterized by flat to gently slop ing stream terraces, which are flanked by a combination of badlands, pediment slopes, and broad valleys. These features were formed by long-continued ero sion in an arid climate of the essentially horizontal, poorly consolidated beds of the Wind River formation. The principal streams of the area flow south eastward. Wind River and Fivemile Creek are perennial streams and the others are intermittent. Ground-water discharge and irrigation return flow have created a major problem in erosion control along Fivemile Creek. Similar conditions might develop along Muddy and lower Cottonwood Creeks when land in their drainage basins is irrigated.

The bedrock exposed in the area ranges in age from Late Cretaceous to early Tertiary (middle Eocene). The Wind River formation of early and middle Eocene age forms the uppermost bedrock formation in the greater part of the area. Unconsolidated deposits of Quaternary age, which consist of terrace gravel, colluvium, eolian sand and silt, and alluvium, mantle the Wind River formation in much of the area.

In the irrigated parts of the project, water for domestic use is obtained chiefly from the sandstone beds of the Wind River formation although some is obtained from the alluvium underlying the bottom land and from the unconsolidated deposits underlying the lower terraces along the Wind River. Although adequate quantities of water for domestic use are available from the Wind River formation, these quantities are not considered to be large enough to warrant pumping of ground water for irrigation. Only a few wells are in the nonirrigated part of the area. When this new land is irrigated, a body of ground water will gradually form in the terrace deposits and the alluvial and colluvial-alluvial deposits. Eventually, the terrace deposits may yield adequate quantities of water for domestic and stock use, but only locally are the alluvial and colluvial-alluvial deposits likely to become suitable aquifers.

In the Riverton irrigation project area, ground water occurs under water-

2 GROUND-WATER RESOURCES, RIVERTON AREA, WYOMING

table conditions near the surface and under artesian conditions in certain strata at both shallow and greater depths. Irrigation is the principal source of recharge to the shallow aquifers; the water level in wells that tap these aquifers fluctuates with irrigation. The depth to water in the shallow wells ranges from less than 1 foot to about 30 feet below the land surface, depend ing on the season of the year and on the length of time the land has been irrigated. The water level in wells that tap the deep confined aquifers, which receive recharge indirectly from surface sources, fluctuates only slightly be cause the recharge and discharge are more constant. In most places the depth to water in wells penetrating the deep confined aquifers is much greater than that in shallow wells, but in certain low areas water from the deep aquifers flows at the surface from wells. Ground water moves from the area of re charge in the direction of the hydraulic gradient and is discharged either by evapotranspiration; by inflow into streams, drains, or lakes; by pumping or flow of wells; or by flow of springs.

Waterlogging and the associated development of saline soils are common in parts of the Riverton irrigation project and adjacent irrigated land. The waterlogging is in part the result of the infiltration of irrigation water in excess of the capacity of the aquifers to store and transmit this added re charge. The solution of the drainage problems involves the consideration of a number of factors, some of which are inadequately known in some parts of the area and require further investigation before fully effective drainage measures can be designed.

The results of an aquifer test to determine the hydrologic characteristics of the Wind River formation at Riverton indicate a transmissibility of 10,000 gallons per day per foot (10,000 gpd per ft) and a storage coefficient of 2 x 1Q-4. The results of the test provide a part of the necessary foundation for the solution of present and future water-supply problems at Riverton and throughout the project area.

Water from shallow aquifers in irrigated tracts in the Riverton irrigation project area generally contains large amounts of dissolved solids that were leached from the soil and rocks by infiltrating irrigation water. However, wells tapping beds that receive considerable recharge from influent canal and drain seepage yield water of relatively low mineralization. Dilute water is obtained also from some shallow wells in the alluvial bottom lands and on low stream terraces that border the Wind River. Water from deep aquifers generally is more dilute than that from shallow aquifers. However, ground water from the deeper aquifers, unmixed with irrigation water, geneally has a percent sodium greater than 80.

Analyses of salt crusts on the ground surface in low areas that are affected by effluent seepage and a high water table show predominance of sodium sulfate salinity, and from determinations of the water-soluble and acid- soluble substances in several samples of soil and shale it is apparent that harmful concentrations of salts are being deposited in poorly drained areas. Although most of the soil in the Midvale irrigation district is of the normal arid type, analyses of soil samples show that saline, nonsaline alkaline, and saline alkaline types also are present.

INTRODUCTION 5

PURPOSE AND SCOPE OF INVESTIGATION

The purposes of this investigation were to determine (1) the location of available water supplies for farms and towns within the area, (2) the chemical quality of the ground water, (3) the effects of irrigation on ground- and surface-water supplies, (4) the water bearing properties of the aquifers, (5) where drainage problems exist or may occur, and (6) the geologic and hydrologic factors that must be considered in the design of adequate and effective drainage facilities.

The field investigation on which this report is based was made by the writers between June 1948 and November 1951. A study was made of the geologic history, physiography, structure, and stratigraphy of the area, and a geologic map having particular emphasis on ground-water conditions was prepared. The hydrologic properties of the Wind River formation were determined by the pumping-test method. Every well in the area was examined and pertinent available data were recorded. Measurements of the water level were made periodically in selected wells throughout the area. Samples of water were collected from wells and surface sources at key locations in the area, and a chemical analysis of the water was made in the laboratory of the United States Geological Survey at Lincoln, Nebr.

The investigation was under the general supervision of A. N. Sayre, chief of the Ground Water Branch, and of G. H. Taylor, regional engineer. F. A. Swenson, district geologist, Billings, Mont., directly supervised the field investigation. The study of the quality of the water was under the general direction of S. K. Love, chief of the Quality of Water Branch, and under the direct supervision of P. C. Benedict, regional engineer.

PREVIOUS INVESTIGATIONS

Little detailed work related to ground water had been done pre viously in the report area. The geology of the Boysen area, which includes the northern part of the Riverton project, was described by Tourtelot and Thompson (1948). The results of the mapping of the remander of the Riverton area by the Fuels Branch of the Geological Survey during the 1949, 1950, and 1951 field seasons have not yet been published.

The report by Tourtelot and Thompson (1948) and other reports dealing with general regional geology, which have been very useful to the authors, are listed in a bibliography at the end of this report.


METHODS OF MAPPING

The geology of the area was mapped on aerial photographs and the data transferred to a base map prepared by the Topographic Division of the Geological Survey from aerial photographs. The scale of the map was 1:24,000.

Altitudes of wells were estimated from Bureau of Reclamation topographic maps of the area or were determined by third-order leveling from benchmarks of either the Geological Survey or the Bureau of Reclamation. The terraces were correlated by use of an altimeter or topographic maps. During the mapping the thickness of the gravel in the terrace deposits was measured roughly by hand level wherever the top and bottom of the gravel were exposed at the terrace edge. However, in most places a lack of clean exposures and the large amount of mantling material on almost all terrace faces interfered with the determination of the exact thicknesses of the overburden, and estimates had to be made.

Precise location of the contact between colluvial-alluvial or allu vial deposits and bedrock proved to be very difficult. Consequently, the units that were mapped indicate the predominant rock type; other rocks or sediments present were not considered mappable. A description of the kind and amounts of mantling deposits is given later in this report.

ACKNOWLEDGMENTS

The writers are indebted to the many persons who contributed information and assistance in the field and to those who aided in the preparation and review of this report. Earl Sullivan, James Mariner, Edward O'Hara, Martin Norman, and Homer Harry, well drillers, furnished information pertaining to wells they had drilled in the area. The Farmers Home Administration also made available much information on wells. The Bureau of Reclamation supplied maps and furnished basic data relating to ground waterand drainage. The Soil Conservation Service and the BureauIndian Affairs likewise were of assistance. The wholehearted co operation of the residents of the area greatly assisted the field studies.

WELL-NUMBERING SYSTEMEach well in the area covered by this investigation is numbered

according to its location within the Bureau of Land Management system of land subdivision. (See fig. 3). The first letter (a capi tal) of a well number indicates the quadrant of the meridian and baseline system in which the well is located; the quadrants s.re lettered A, B, C, and D in a counterclockwise direction beginning

The wells in the Riverton proj ect area are in the northeast (A), the northwest (B), or the south east (D) quadrants of the Wind River principal meridian and baseline system. The first numeral of a well number indicates the township, the second the range, and the third the section. The


lowercased letters following the section number indicate the loca tion of the well within the section; the first letter denotes the quarter section and the second the quarter-quarter section, or 40-acre tract. The lowercase letters also are assigned in a counter clockwise direction and begin in the northeast quarter or quarter- quarter section. If two or more wells are in a 40-acre tract, they are differentiated by consecutive numbers (beginning with 1) that are added to the well number.

GEOGRAPHY

CLIMATE

The climate of the Riverton irrigation project area is semiarid to arid and is characterized by great deviations from normal pre cipitation. United States Weather Bureau stations at the Wind River diversion dam and at Pavillion and Riverton have complete records for 28- to 31-year periods. (See table 1.) During the past 31 years at the Wind River diversion dam, at the extreme western end of the area, the annual precipitation has ranged from 5.05 to 16.28 inches and has averaged 9.83 inches. During the past 28 years at Pavillion, in the northwestern part of the area,

the annual precipitation has ranged from 5.20 to 15.61 inches and has averaged 9.25 inches. During the past 29 years at Riverton, at the southern tip of the area, the annual precipitation has ranged from 6.05 to 18.43 inches and has averaged 9.62 inches. The yearly distribution of precipitation at these three stations is gen erally similar, although the dry and wet years do not always coin cide. (See fig. 4.)


The graphs of cumulative departure from average precipitation at the Wind River diversion dam and at Pavillion and Riverton (fig. 5) illustrate the periods of generally above-average and below-average precipitation. The periods of above-average pre cipitation are shown by a rising line, and the periods of below- average precipitation by a declining line. At the Wind River diversion dam the period 5 of generally below-average precipitationwere from 1920 through 1926, from 1931 through 1939, and from

1941 through 1943; the periods of generally above-average pre cipitation were from 1926 through 1931, from 1939 through 1941, and from 1943 through 1951. At Pavillion precipitation was about average in 1924, generally below average from 1924 through 1940, and generally above average from 1940 through 1951. At Riverton the precipitation was above average in 1923, about aver age from 1923 through 1930, below average from 1930 through 1940, above average from 1940 through 1947, and below average from 1947 through 1951. At all three stations the yearly variations do not always conform with the general trend of the periods.

About 45 percent of the annual precipitation falls during April, May, and June, and 22 percent falls in September and October.

FIGURE 6. Average monthly precipitation at three stations in the Riverton irrigation project area.

About 19 percent of the annual precipitation falls in May. The win ter months are driest at all stations. (See fig. 6.) The wet period in the spring usually comes too early and the wet period in the fall too late for the growing season of most crops. At times the fall precipitation is a handicap to the harvesting of crops and causes some loss. In the middle of the growing season the precipitation is scanty and the flow of streams is low. This deficiency is allevi ated somewhat by the use for irrigation of about 182,000 acre-feet of water from Bull Lake and Pilot Butte Reservoirs; the water is stored during the spring months when snowmelt and runoff are at a maximum.

The frost-free season has ranged from 75 to 163 days and aver ages about 128 days.


AGRICULTURE AND INDUSTRY

The principal crops in the Riverton irrigation project area are beans, beets, potatoes, oats, and alfalfa hay; alfalfa and clover (for seed), wheat, and barley also are raised. In 1951 the Bureau of Reclamation reported 52,026 acres under cultivation on the River- ton irrigation project. The total value of crops was $2,233,209, which is an average return of $42.92 per acre.

Oats, the major crop, were grown on 9,096 acres, and alfalfa hay and alfalfa for seed were grown on 7,778 and 5,375 acres, respec tively. The total return from the alfalfa-seed crop was $302,400; the returns from oats and alfalfa hay ranked second and third and were $255,759 and $240,614, respectively. The highest average return per acre, $568.75, was for seed from 32 acres of tall wheat grass; the second highest return was $374.02 per acre from pota toes ; and the third was $123.81 per acre for sugar beets.

No mining is done in the area, although coal of poor quality has been mined near Pilot Butte in the western part of the area.

The oil industry is of considerable importance in the Riverton irrigation project area. Two oil fields, Steamboat Butte and Pilot Butte, are in T. 3 N., R. 1 W., at the western end of the area. Both produce oil from the Tensleep sandstone. A recently drilled well at the Pilot Butte field has also encountered oil at a shallow depth in the Muddy sandstone member of the Thermopolis shale. Nu merous other oil fields are adjacent to the area; the Riverton Dome oil field is the closest and is about 7 miles southeast of Riverton. Four wells have been drilled in this field since its discovery in 1948. Production here is also primarily from the Tensleep sandstone.

HISTORY OF IRRIGATION

The land in the Riverton irrigation project was ceded by the Indians of the Shoshone Reservation to the United States Govern ment on March 3, 1905. After a preliminary survey by the State of Wyoming, the area was opened for settlement in 1906. At that time construction was started on the first irrigation canal. This canal, which was built by the Wyoming Central Irrigation Co. and which is known as the Wyoming No. 2 canal, was completed in April 1907. (See fig. 2.) Water from the canal irrigates low lands that are mainly north and east of Riverton. In 1914, the settlers formed the Riverton Ditch Co., which constructed the Le Clair (Riverton No. 2) canal. The intake of this canal is about 15 miles northwest of Riverton, and the canal supplies water to low lands to the west along the river and also to land above the Wyo-

GEOGRAPHY 13

ming No. 2 canal. Two small private canals, the Hurtado and Aragon ditches, irrigate the lowlands west of the Le Clair canal.

The Bureau of Reclamation assumed responsibility for the present Riverton irrigation project in 1918 and began active con struction in 1920. The Wind River diversion dam, in the north west corner of the area, was completed in 1923. Pilot Butte Reservoir, which has a capacity of 30,000 acre-feet, and Pilot Butte power plant, at the intake of Pilot Butte Reservoir, were completed in 1926. Bull Lake Reservoir, completed in 1938, is about 5 miles southwest of the Wind River diversion dam and has a usable ca pacity of 152,000 acre-feet. The main Wyoming canal was com pleted from the Wind River diversion dam to Pavillion in 1925; since that time, the Pilot canal and numerous laterals have been constructed, and in 1950 the northward extension of the main Wyoming canal brought irrigation to the North Pavillion area. (See fig. 2.) A further extension of the main Wyoming canal has now been completed, which supplies water to additional acreage north of Fivemile Creek; a tunnel, which was completed in 1949, through Indian Ridge a prominent high divide lying between Fivemile Creek and Muddy Creek carries water to the North Portal area and Muddy Creek terraces. The North Portal area (fig. 2) was irrigated for the first time in 1951. Irrigation water was applied in 1951 to 77,716 acres in the Riverton area, of which 53,897 acres were either a part of or associated with the Bureau of Reclamation Riverton project and 23,819 acres were privately irri gated from the Le Clair (Riverton No. 2) canal, the Wyoming No. 2 canal, and the two small canals in the western part of the area. Plans for the irrigation of an additional 31,344 acres of land south and east of the North Portal area (Muddy Ridge exten sion) are now being considered.

PHYSIOGRAPHYThe Riverton irrigation project area is in the northwestern part

of the Wind River basin. This basin is a large sediment-filled, northwest-trending structural trough, which is bounded on the southwest by the anticlinal Wind River Mountains, on the north by the anticlinal Owl Creek Mountains, and on the south and east by the deeply eroded Sweetwater uplift and related structures. The most striking topographic features of the area are the promi nent stream terraces, pediment slopes, and broad valleys that have been formed in the easily eroded Tertiary deposits.

The terraces are a series of gently sloping surfaces along each stream and they range from a few feet to several hundred feet above the present level of the stream. They parallel and are prin-


cipally on the north side of the parent streams. The terraces form steps to the north from the alluvial bottoms of the streams; along Muddy Creek they are interrupted by broad troughs in which closed, wind-scoured depressions have been formed. The terraces are underlain by thick deposits of well-rounded gravel. The up permost terrace in most places forms the interstream divide and is flanked to the north by a combination of pediment slopes, bad lands, and lower-terrace remnants. In places the more resistant sandstone beds that were formerly overlain by terrace deposits have retarded erosion and formed rock-capped buttes.

Highly dissected bedrock slopes flank terraces throughout the area. They form the floors of the smaller valleys between terraces but are best developed on the south sides of the broad valleys formed by the main streams of the area. (See pi. 4.) Colluvial- alluvial deposits derived from the weathering of the bedrock ex posed in the higher terraces and buttes mantle much of the bedrock slope. Alluvium occurs as valley fill along the drain&geways through the area. Knobs and hills of bedrock project above the colluvial-alluvial mantle in many places.

GEOLOGIC HISTORY

The details of the physiographic history of the area are imper fectly known; however, it is generally agreed that the following events occurred in the Wind River basin region in the late Mesozoic and the Cenozoic eras.

The ancestral Wind River basin and adjacent mountain struc tures were formed essentially during the Laramide revolution in Late Cretaceous and early Tertiary time. Erosion of the moun tains and highlands resulted in the deposition of much rock debris in the basin. Much of it was deposited in sheets or as channel fill. By middle or late Tertiary time the basin was completely filled with sediments, which covered the Owl Creek Mountains and which either covered or graded into peneplaned surfaces, or pediments, on the adjacent higher Wind River Mountains. In late Tertiary time, owing either to uplift or to climatic change, active aggrada tion in the Wind River basin ceased and active degradation began. Erosion has been the dominant geologic process in the region since late Tertiary time; the poorly consolidated sediments in the basin are still being removed. The removal of Tertiary sediments again exposed the more erosion-resistant mountain ranges that had been buried. The present course of the Wind River was superimposed on the area from its position on the Tertiary sediments. Minor interruptions in the long cycle of erosion are reflected by the pres ent topography of the basin.

PHYSIOGRAPHY 15

GEOMORPHOLOGY

The topography of the area has been formed principally by ero sion. The main factors that determine the rate of erosion are the climate and the lithologic character and attitude of the bedrock. The arid climate of the area is not conducive to chemical weather ing. However, because vegetation is sparse, even the small quan tity of water either in streams, as sheet flood and rill wash, or in direct precipitation is a very effective erosive agent. The attitude and lithologic character of the strata of the Wind River formation favor erosion because the formation is essentially hori zontal and consists of poorly consolidated sandstone, siltstone, and shale. Several thousand feet of sediments have been removed by repeated cycles of erosion. At the start of such a cycle streams flowing from the flanks of the mountains become entrenched; when such streams approach a graded condition or reach a local tempo rary base level, they meander from side to side and both widen and level their valley floors. As the valleys are widened and leveled, the streams deposit gravel. It is the gravel deposited in this part of the cycle that now underlies the surface of each of the terraces. Repetition of the cycle of downcutting and subsequent valley widening resulted in the development of the terraces.

The position of the terraces in relation to the present streams of the area indicates that the ancestral streams constructed the ter races. Each terrace represents a period of relative stability when the stream enlarged its flood plain. The scarps between terraces indicate periods of instability and accelerated erosion during which the stream entrenched itself before again expanding its flood plain. The broad extent of the terraces and their more gentle slope, the large size of the gravel pebbles in the terrace deposits, and the uniform thickness of the deposits indicate that the terrace-forming streams were perennial and were relatively large in comparison to the present streams. Each terrace marks a major change in the regimen of the stream. The possible basic factors that, singly or in combination, may have been responsible for the changes are: regional uplift or tilting, climatic change, changes in the size of the area being drained by the stream, and changes in the factors controlling the local base level.

The climatic changes that would be necessary to produce terrace development would be of the magnitude of those that are associated with the alternation of glacial and interglacial stages or substages.

A change in the size of the drainage area, such as would result from the capture of one stream by another, would increase the flow and erosive power of the capturing stream.


The Wind River is assumed to have been the local base level for all its tributaries during the period of terrace development. Any downstream or upstream drainage changes in the Wind River altered the flow of the river, affected its cutting ability, and caused a change in the base level of the tributary streams. Likewise, any downvalley obstructions, such as the more resistant formations cropping out in the Wind River Canyon, created at that point a temporary base level that affected the upstream part of the river and the tributary streams. Therefore, the tributary streams of the Wind River formed terraces that correspond to those formed by the Wind River. (See pi. 1.)

In general, during the period of terrace formation, Fivemile, Muddy, and Cottonwood Creeks moved progressively to the south. A natural tendency for a stream flowing parallel to the front of a mountain range is to shift its course farther from the main source of water, the mountains. The principal tributaries rise on the mountain front and by building fans of alluvial material they force the major stream away from the mountains. Another factor that may contribute to the migration of the main stream is the "jetting action" of the tributary streams upon entering the main stream at right angles. The inflow of water from the tributaries forces the current of the major stream against the opposite bank and the stream migrates away from the mountain front, which is the source of the larger tributaries. The shorter tributaries on the other side of the main stream seldom flow; hence, they are unable to compete with the larger tributaries from the mountain front. Through the combined influence of these factors Fivemile, Muddy, and Cottonwood Creeks have migrated away from the Owl Creek Mountains.

The precise ages of the terrace surfaces have not been deter mined, but the volcanic material which was derived from the Absaroka Mountains and which is present in the gravel of the uppermost terraces indicates that these and all lower surfaces are younger than the mountains, which were formed in Eocene or early Oligocene time (Tourtelot and Thompson, 1948). Inasmuch as the uppermost terrace (terrace Ti3, or Lost Wells Butte) is considered to be the Black Rock surface of Blackwelder (1915, p. 312-316), and because that surface was correlated by him as pre- Kansan (pre-Buffalo in Wyoming), terrace Ti3 probably is of Aftonian age. This then suggests a post-Aftonian age for all lower or more recent terraces within the area.

Concurrent with the action of major streams, direct precipitation by contributing to ephemeral side streams and by causing rill wash and sheet flood has produced extensive badlands and, by

PHYSIOGRAPHY 17

contributing to escarpment retreat, has been a factor in the forma tion of pediments at the base of the escarpments. Contemporane ous with each stage of terrace development, erosion modified the escarpments of the interstream divides and formed for each terrace which represents a temporary base level a complementary slope on bedrock extending southward from the streams to the divides.

After terrace T2 had been formed, the streams of the area were rejuvenated; the principal streams cut a trench in the bedrock 50 to 75 feet below the terrace, and the intermittent tributaries be came incised in the pediment slopes. A period of alluviation, during which the principal alluvial terrace (terrace TI) along the main streams is believed to have been formed, followed the period of downcutting. Then, owing to the continued changes in climatic conditions, the streams cut their present channels and alluvial fans spread over much of the pediments and, in some places, along the streams.

Three pronounced troughs cross the divide between Muddy and Cottonwood Creeks. (See pi. 1; shown as Tw in sees. 6 and 7, T. 4 N., R. 3 E.; sees. 22 and 27, T. 4 N., R. 4 E.; and in sees. 11, 13, and 14, T. 4 N., R. 4 E.) These are wind-modified channels of former tributaries of Muddy Creek that flowed southward off the flanks of the Owl Creek Mountains. Headward erosion by Cotton- wood Creek has progressively pirated these Muddy Creek tribu taries and left the old channels through the terraces as a series of wind gaps. The geologic map (pi. 1) reveals this progressive pi racy. The easternmost trough probably was a through drainage course at least until terrace T3 was formed, the central trough until terrace T2 was formed, and the westernmost trough until after terrace T2 was formed. The Cottonwood drain has exposed the old channel gravel in the lower part of the easternmost trough. Although gravel is lacking in the upper part of this trough, it may have been removed by stormflows that have been concentrated in this natural drainageway during torrential downpours. The other two troughs are considered to have comparable histories. The po sition of the Cottonwood tributaries in relation to the position of the postulated abandoned valleys also substantiates this conclusion. The study of adjacent areas further supports the above explana tion of the development of the transverse valleys. For example, along the east flank of the Maverick Springs and Little Dome structures, the headwaters of Muddy Creek appear to have cap tured the headwaters of the Fivemile Creek tributary that flows southward in Hurley Draw.

Associated with the piracy of Muddy Creek tributaries by Cot-


tonwood Creek, and offering still further evidence of this piracy, is the progressive increase in gradient of Muddy Creek during the period of terrace formation and the consequent increase in height above the creek of the downstream part of any terrace. Such an increase in gradient would have been necessitated by the loss of water in Muddy Creek due to piracy.

Locally, wind action has been an effective agent of erosion. The wind has scoured out closed depressions in the soft sediments that are exposed in abandoned drainageways and also has modified these by local deposition. Silt and sand from these areas as well as from slopes and level surfaces have been removed by the wind and deposited to form hummocks and dunes in sheltered places or where vegetation is present. The removal of sand and silt from deposits that also contain gravel has left a residual concentration of pebbles, which is known as "desert pavement." The abrasive action of sand-bearing wind on resistant gravel has produced many faceted pebbles (ventifacts) and the present form of the many rounded pedestals, pinnacles, and bowllike openings in easily eroded sandstone.

Precipitation has produced a complex pattern of solution sculp turing on pebbles of impure limestone which mantle the higher terraces of the area.

DRAINAGE SYSTEM

The principal streams of the area flow southeastward parallel to the trend of the structural trough of the Wind River basin. The Wind River heads in the Absaroka Mountains at the extreme north western corner of the basin and is fed by streams flowing off the Wind River and Owl Creek Mountains. It flows southeastward to its confluence with the Popo Agie, where it turns sharply north eastward and thence flows north through the Wind River Canyon, which cuts across the axis of the Owl Creek Mountains, beyond which point it is known as the Bighorn River. The principal trib utaries within the Riverton project are Fivemile Creek, Muddy Creek, and Cottonwood Creek also named Dry Muddy Creek on some maps. Fivemile Creek heads on the Circle Ridge anticline, flows through the central part of the area, and enters the Wind River at a point about 20 miles downstream from the confluence of the Popo Agie and Wind Rivers. Muddy Creek, which drains a larger area than either Cottonwood or Fivemile Creeks, heads in the Owl Creek Mountains and flows through the northern part of the area; it enters the Wind River about 7 miles downstream from the mouth of Fivemile Creek. Cottonwood Creek flows along the

PHYSIOGRAPHY 19

north boundary of the area, is fed by streams that flow southward from the flanks of the Owl Creek Mountains, and empties into the Wind River about 6 miles downstream from the mouth of Muddy Creek.

STREAMFLOW

WIND RIVER

The Wind River is the master stream in the area. It is peren nial and is the primary source of irrigation water for the area as well as for the Bighorn Basin to the north.

The Geological Survey maintains a gaging station on the Wind River at Riverton. The discharge figures for this station for the 23-year period 1929 through 1951 are given in table 2. However, these figures do not represent the natural discharge because numer ous diversions for irrigation are made upstream from Riverton during the summer months.

FIVEMILE CREEK

Before the abnormally wet year of 1923, Fivemile Creek was re ported to be little more than a large gully and was dry much of the year. The flood of 1923, which is reported to have reached a maxi mum flow of 3,500 cfs, greatly enlarged the stream channel and, since the opening of the Riverton irrigation project, a perennial flow has been maintained through the middle and lower course of the creek.

Discharge measurements of Fivemile Creek near its mouth were made by the Geological Survey from May 1941 to September 1942; measurements were resumed in the fall of 1948. The mean dis charge for each month during the two periods of record is sum marized in table 3.. The large increase in discharge between the periods 1941-42 and 1948-51 is due mainly to return flow from irrigation, which in the meantime had been extended considerably. Gaging stations also have been established on the middle and lower courses of Fivemile Creek.

1 This and all subsequent measurements are preliminary, previously unpublished figures and are sub ject to revision.

The average discharge for the water year ending September 30, 1942, was 54.8 cfs, and for the water years ending September 30, 1949, 1950, and 1951, was 93.0, 121.0, and 119.0 cfs, respectively. The average discharge during the 1949, 1950, and 1951 irrigation seasons (May 1 to September 30) was 164.4, 232.4, and 221.7 cfs, respectively; most of the water during this period originated as return flow from irrigation on the Riverton project. The average flow during the remaining part (October 1 to April 30) of the same years was 42.0, 40.1, and 44.4 cfs, respectively. The average dis charge during November, December, January, and February was 34.4, 32.7, and 47.2 cfs, respectively; this is considered to be the base flow and to represent approximately the mean total ground- water inflow to Fivemile Creek during this period. The maximum measured discharge was 3,200 cfs on August 7, 1941. The mini mum discharge during the period of record was 1.0 cfs for January 4-6, 1942.

The artificial rejuvenation of Fivemile Creek in its middle and lower course is a result of irrigation on the Riverton project. The increased flow is caused by surface runoff from irrigated lands, by waste water from irrigation, and by increased discharge of ground water from the project lands. The principal effects of the reju venation have been the increased activity of the stream as an agent of erosion and the consequent increase in the silt load carried by

PHYSIOGRAPHY 21

the creek to the Wind River. (See pi. 5A.) The erosion is de stroying farmland adjacent to the creek, and the heavy load of sediment delivered to the Wind River has created a siltation prob lem at Boysen Reservoir.

The problem of minimizing erosion by Fivemile Creek can best be solved after a careful analysis has been made of the cause and effect relation of the contributing factors, among which is ground water. Although its relative importance has not yet been thor oughly evaluated, observations indicate that ground water, by saturating the materials in the stream banks, accelerates basal sapping and lowers the resistance of creek banks to flood erosion.

MUDDY CREEK

Muddy Creek, like Fivemile Creek, was greatly enlarged by the flood of 1923. A slope-area measurement made soon after this flood indicated a maximum discharge of 16,300 cfs. Since this time Muddy Creek has been dry throughout much of the year, and at present it is intermittent across the project area. Discharge measurements of the flow of Muddy Creek near its mouth have been made by the Geological Survey since March 1, 1949. These figures represent average flow during the respective months and do not necessarily indicate continuous flow; a fairly large flow is possible during part of a month, and no flow may occur the remain der of the month. The monthly mean discharge of Muddy Creek for the period March 1949 to September 1951 is given in table 4.

2 Waste irrigation water first appeared.

The greatest streamflow normally occurs during the summer months and, except for the relatively large amounts of waste water discharged into the creek during the irrigation season of 1950 and 1951, these figures essentially represent the runoff originating up stream from the report area.


Muddy Creek is now in a state of adjustment to its new normal flow, load, and gradient. The banks appear to be stabilized by a protective vegetative cover, and there is little evidence that normal flow accomplishes much lateral erosion or much downcutting. This condition of adjustment is temporarily interrupted during flood flows, which erode more actively and which carry greater amounts of sediment. The sediment load transported at these times either is deposited lower in the course of the creek, where the lesser gradient favors aggradation, or is emptied into the Wind River; the sediment constitutes a large portion of the total load carried by the creek. Of importance, then, is the increase in flow that will result when additional land is irrigated in the drainage basin of Muddy Creek. The addition of waste irrigation water and ground-water discharge to the present normal flow will reju venate the creek, and with continued irrigation it will become per ennial and will develop erosion problems similar to those along Fivemile Creek. Obviously, erosion-control measures will be most effective the earlier they are undertaken.

COTTONWOOD CREEK

Because little or no land is irrigated at the present time in the area drained by Cottonwood Creek, the flow of the creek is both low and intermittent. (See table 5.)

The irrigation of land adjacent to Cottonwood Creek and the discharge of irrigation waste water into Cottonwood Creek have been proposed. In the making of such plans, due consideration should be given to the expected increase of the normal flow of Cot tonwood Creek and the consequent erosion problems in the lower part of the creek.


GEOLOGIC FORMATIONS AND THEIR WATER-BEARING PROPERTIES

Rocks ranging in age from Late Cretaceous to Recent are exposed in the Riverton project area and adjacent lands included in this investigation. The oldest rocks are exposed only at the western end of the area in the vicinity of the Pilot Butte and Steamboat Butte oil fields. The Cody shale is exposed on the crest of both the Pilot Butte and Steamboat Butte anticlines and the overlying Mesaverde and Meeteetse formations form hogbacks on the flanks of these oil structures. Younger rocks underlie the remainder of the area; they consist of the Wind River formation of Tertiary age and of alluvial, colluvial, and eolian deposits of Quaternary age.

CRETACEOUS SYSTEM

UPPER CRETACEOUS SERIESCODY SHALE AND MESAVERDE FORMATION, UNDIFFERENTIATED

Areal extent. In the area of investigation, rocks of the Cody shale and Mesaverde formation, undifferentiated, are exposed prin cipally in a narrow band about three-fourths of a mile wide along the northeast flank of the Pilot Butte anticline. They are exposed also along the edge of the escarpment between terrace T5 and the alluvial plain of the Wind River where it crosses the Pilot Butte anticline.

Description. The Cody shale and Mesaverde formation consist of soft gray to black shale and fine-grained light-colored massive to thin-bedded sandstone containing numerous coal beds (Love, 1948, p. Ill). The thin beds of rusty sandstone, coaly gray shale, and coal exposed along the Pilot Butte anticline probably are only the upper part of the sequence. The dip of the beds away from the crest of the structure is about 15° to 40° (Matter, 1948) and the more resistant beds form hogbacks. In places the beds are complexly faulted.

Occurrence of ground water. No wells are known to penetrate the Mesaverde formation in the investigated area; consequently, the quality and quantity of water in this formation are unknown.

Two wells penetrate rocks of the sequence, presumably lenticular sandstone in the upper part of the Cody shale. These yield mod erate quantities of water, but the quality is poor.

TERTIARY SYSTEMEOCENE SERIES

WIND RIVER FORMATION

Areal extent. The Wind River formation underlies all the in vestigated area except the western part where older rocks are exposed.


Description. The Wind River formation was first named and described by Hayden (1862, p. 125-127) from exposures in the Wind River valley. He applied this name to sediments that lie with slight discordance on the lignite beds of the Fort Union forma tion of Paleocene age and that are overlain by deposits of the White River formation of Oligocene age. The contact of the Wind River formation with the Fort Union or White River formations was not observed by the writers within the investigated area. The Fort Union has been described, however, in the Shotgun Butte area west and north of the investigated area (Keefer and Troyer, 1956) and several isolated remnants are exposed between Conant and Canyon Creeks in the east-central part of Fremont County (about25 miles east of Riverton). The White River is known to be pres ent along the southern margin of the Absaroka Range and in south eastern Fremont County on Beaver Rim of the Sweetwater uplift.

The Wind River formation consists of a complex series of interbedded lenticular sandstone, siltstone, shale, claystone, conglomer ate tuff, and fresh-water limestone. (See pi. 5£.) Tourtelot and Thompson (1948) have identified two facies in this formation: one brightly colored, the other drably colored. The brightly col ored facies consists of red, violet, blue, yellow, and white hard fine-grained sandstone and siltstone; fresh-water limestone; and a basal conglomerate containing sporadic roundstones of foreign quartzite and volcanic rock. The drably colored facies consists of gray and greenish-gray claystone and siltstone and channel depos its of yellow to brown coarse-grained sandstone. Locally, the drably colored facies contains dull variegated beds and carbona ceous sequences. The division of the formation into two facies is primarily on the basis of color and lithologic character; it has little time-stratigraphic significance because these facies interfinger and their lithologic types and colors intermingle. Fossil vertebrates have been used by Tourtelot and Thompson to date the drably col ored facies as chiefly of "Wasatchian" (early Eocene) age, and fossil vertebrates and plants have been used to date the brightly colored facies as chiefly of "Bridgerian" (middle Eocene) age, or as transitional between "Wasatchian" and "Bridgerian." How ever, the presence of "Bridgerian" fossils and plants in the upper part of the drably colored facies and the presence of "Wasatchian" fossils in the lower part of the brightly colored facies indicates that a "Wasatchian" and "Bridgerian" age should be ascribed to both facies. In this area the brightly colored facies underlies the north margin of the Wind River basin and interfingers with the drably colored facies toward the center of the basin. Toward the Owl Creek Mountains, which are north of the area under investigation,

GEOLOGIC FORMATIONS AND THEIR WATER-BEARING PROPERTIES 25

both f acies are overlain by green and brown andesite tuff and fresh water limestone which grade laterally along the mountain front into nontuffaceous red siltstone and conglomerate.

Tourtelot and Thompson (1948) mapped the drably colored fa des of the Wind River formation in the northern part of the report area; this f acies probstbly underlies the entire area described in this report. Except locally, the beds are essentially horizontal or dip gently toward the center of the basin; on the west flank of the Pilot Butte structure the dip of the Wind River formation is about 7° W., and in sec. 5, T. 4 N., R. 6 E., the apparent dip is as much as 20° toward the Owl Creek Mountains.

The outcrops consist of sandstone, siltstone, shale, claystone, and sediments gradational between these. Shale and thin-bedded to massive siltstone and sandstone are the commonest rock types. The sandstone beds are predominantly yellow and brown, but some are gray and grayish green. They generally are fine- to medium- grained, micaceous, poorly sorted, and loosely cemented. They were deposited generally as lenticular sheets or channel deposits and are commonly crossbedded. The shale, siltstone, and claystone are generally gray, greenish gray, or grayish green; some dull-red to purple shale is exposed in the lower part of the outcrops. Shale and claystone generally are fairly soft; siltstone is typically blocky and poorly cemented. Most of the sediments are poorly consoli dated, but firmly cemented lenses of rather coarse grained sand stone or conglomerate or concretions of sandstone are present in some places, particularly in the channel deposits. The cemented lenses are irregular, elongate masses, some of which are more than 3 feet thick; they resist erosion and form ledges or ridges. The concretions are very hard, somewhat irregular but commonly smoothly rounded, and generally more than 2 feet in diameter. They litter the landscape in places where softer surrounding ma terials.have been removed by erosion. Limestone nodules also are common in the sediments. Beds of carbonaceous shale, some of which contain plant remains and which are associated with beds of bentonitic clay and some tuff, occur in places throughout the area but are exposed mainly along east-central and eastern Muddy Creek and in sec. 17, T. 4 N., R. 6 E., along buttes that border the Wind River. Petrified wood is commonly associated with this carbonaceous sequence. Numerous joints and other fractures, many of which are filled with calcareous or ferruginous material, traverse the rocks. Two large faults in the area were mapped by Tourtelot and Thompson (1948). (See pi. 1.) Small faults are common.

The thickness of the drably colored f acies in the area described


in this report is not definitely known. A thickness of 1,500 to 2,500 feet of the Wind River formation reportedly was penetrated by several old oil tests within the area, but the information pos sibly is unreliable. The formation is known to be less than 100 feet thick in the Steamboat Butte oil field and more than 2,000 feet thick in several old oil tests northeast of Shoshone, which is con sidered to be in the deepest part of the Wind River basin. The maximum exposed thickness of the formation in the Boysen area to the north is reported to be 913 feet (Tourtelot and Thompson, 1948). Southeast of Riverton, at the Riverton dome, oil wells are reported to have penetrated about 1,500 feet of the Wind River formation. Therefore, the thickness of the formation within the report area probably is 1,000 to 2,000 feet.

Occurrence of ground water. Most wells in the area obtain water from the lenticular beds of sandstone in the Wind River for mation. The water in the sandstone beds generally is under artesian pressure and rises in wells when the confining beds are penetrated; in some parts of the area water flows at the land sur face from wells on low ground.

Infiltrating irrigation water is the source of most of the re charge to the artesian aquifers, and the water level in shallow wells rises during the irrigation season. Because the irrigation water leaches minerals from the soil and carries them down to the zone of saturation, the quality of water in the shallow aquifers gen erally is unsatisfactory for domestic use except where the shallow aquifers are recharged by infiltration from streams or canals.

Surface water probably is the principal source of recharge to the deeper artesian aquifers also; however, owing to their distance from the outcrop, and their low transmissibility, and also to the fairly constant discharge from them, the water level in wells tap ping these aquifers fluctuates only slightly throughout the year, and the quality of the water is relatively uniform and generally satisfactory for domestic use.

Some water is under water-table conditions in the upper, badly weathered part of the Wind River formation. This occurrence is described in the discussion of surficial deposits mantling the Wind River formation.

Although wells penetrating the Wind River formation do not yield large quantities of water, this formation is the best present and potential source of water for domestic use in this area. At the present time, the largest quantity of water produced from any well drilled into the Wind River formation is a little more than 200 gpm; a larger quantity of water probably can be obtained only by drilling wells into deeper aquifers in the formation.

attributed to direct recharge of the surficial deposits by seepage from irrigation. However, it is possible that under certain con ditions shallow artesian water may be contributing to waterlog ging. Under favorable topographic and hydrologic conditions, leakage through confining beds to the overlying unconfined aquifer may occur, and waterlogging may be accelerated by the addition of this water. The possibility of such a contribution to waterlogging should be fully investigated.

TERRACE DEPOSITS

In the area described in this report, the 13 distinct terraces along the principal lines of drainage, as well as several interstream terrace remnants, are underlain by deposits of roughly angular to subrounded gravel, presumably of Quaternary age and derived from sources to the west and north. (See table 6.) The gravel derived from the Owl Creek Mountains to the north contains angu lar pieces of dolomite, limestone, and igneous rocks, whereas the gravel derived from the mountains near the head of the Wind River consists mainly of rounded fragments of pre-Cambrian ig neous and metamorphic rocks and Tertiary volcanic materials.

The principal terraces have been correlated only tentatively; their relationship and relative position are shown on plate 1.

Areal extent and description of terraces. Terrace T! is present only along the big bends of the Wind River at Riverton and in T. 2 N., R. 6 E. It is a relatively flat surface about 7 miles long and y± to 1^4 miles wide in the Riverton area and about 2Vfc miles long and less than half a mile wide in T. 2 N., R. 6 E. Terrace T\ ranges in height above the Wind River from 15 feet at its upstream end to 22 feet at its downstream end and is underlain by 7 to 20 feet of gravel capped by 1 to 2 feet of finer material. The average thickness of gravel is about 12 feet in the Riverton area, but it is more nearly 20 feet in T. 2 N., R. 6 E. This terrace is believed to correlate with the highest of three low alluvial surfaces, which are mapped as alluvium along Fivemile, Muddy, and Cottonwood Creeks. (See pi. 1.)

Terrace T2 is one of the most extensive terraces in the area. It is present in places along the entire course of the Wind River, along Fivemile Creek in its western and eastern parts, and along Muddy and Cottonwood Creeks in their central and eastern parts. Ter race T2 generally is highly dissected and consists of a series of iso lated remnants that are less than 1 mile long and one-fourth of a mile wide. However, along the big bends of the Wind River at Riverton and in T. 2 N., R. 6 E., and along Muddy and Central Cottonwood Creeks this terrace is 3 to 14 miles long and about % to 2 miles wide. Its height ranges from 40 to 65 feet along the Wind River, Muddy, and Cottonwood Creeks but from 28 to 33 feet above Fivemile Creek where available evidence indicates greater alluviation of the creek channel after terrace T2 was formed. The terrace gravel, which ranges in thickness from 2 to 20 feet, generally is about 12 feet thick in the Riverton area and about 20 feet thick in T. 2 N., R. 6 E. The terrace surface is mantled locally by alluvial- fan deposits, which range in thickness from 1 to 25 feet in the Riverton area and from 4 to 70 feet in Tps. 2 and 3 N., R. 6 E. In T. 3 N., R. 6 E., all surficial evidence of the terrace is obscured by the alluvial-fan deposits.

The most extensive remants of terrace T3 are along the eastern course of Muddy Creek and along the western course of Cotton- wood Creek where they consist of-a flat to gently rolling surface. Along Muddy Creek they are about 8 miles long, and along Cotton- wood Creek they are about 2 miles long. These remnants are 1/2 to 2 miles wide. Terrace T3 is less extensive along central Five- mile Creek, western and central Muddy Creek, and central and eastern Cottonwood Creek. In these places it consists of a series of highly dissected remnants that generally are 1/2 to 3 miles long


and half a mile wide or less. The height of terrace T3 above Muddy Creek ranges from 65 feet in the western part to 118 feet in the eastern part, and above Fivemile and Cottonwood Creeks it ranges from 70 to 80 feet. The terrace gravel ranges in thickness from 3 to 12 feet, and the overlying finer material is 1 to 2 feet thick. On the outer edge of this terrace, sec. 8, T. 4 N., R. 3 E., layers of epsomite (MgS04 7H20) are present in several places along the contact of the gravel with the underlying shale; the epsomite probably was deposited by ground water.

Terrace T4 is present along the eastern course of Fivemile Creek as an elongate irregular remnant three-fourths of a mile in length; parallel to east-central Muddy Creek it is a fairly broad, gently rolling remnant 5 miles long; and along central and eastern Cotton- wood Creek it is present as a series of small remnants */2 to 1 mile long. The maximum width of terrace T4 is a little more than 1 mile and its height above creek level ranges from about 98 to 110 feet. The thickness of the underlying gravel is rather difficult to determine, but apparently it ranges from 4 to 12 feet; overlying the gravel is a layer of fine-grained material 1 to 2 feet thick. The remnant along Muddy Creek terminates in depressions at both ends, and its inner edge is marked by a series of blowouts.

Terrace T5 is well represented along all the major drainages of the area, but it is most extensive along the western and eastern course of the Wind River, along the east-central part of Fivemile Creek, and along Muddy Creek; it is the most prominent terrace along Fivemile and Muddy Creeks. The terrace remnants are flat to gently rolling and are 7 to 8 miles long and 1/3 to 1*4 miles wide. Elsewhere along the Wind River and along Fivemile, Muddy, and Cottonwood Creeks, the terrace is absent or exists as a series of highly dissected, isolated remnants less than 3 miles long and no wider than 1*4 miles. In many places the only evidence that the terrace once was present is a line of small gravel-capped knolls. The height of terrace T5 above Muddy Creek ranges from 100 feet in the western part to 155 feet in the eastern part, and from 100 to 160 feet above the Wind River and Fivemile and Cottonwood Creeks. The terrace is underlain by about 8 to 20 feet of gravel and about 1 to 2 feet of finer material (pi. 6A) ; the average thick ness of the gravel is about 13 feet. In sec. 36, T. 5 N., R. 2 E., along the southern edge of this terrace north of the main Wyoming canal, layers of gypsum are present at the base of and within the gravel.

Terrace T6 is present in places along the Wind River and Five- mile Creek but is best represented along Muddy Creek. It exists primarily as a series of highly dissected long and narrow remnants,


which are 1 to 6 miles long and are less than half a mile wide. The largest remnants are along the western and southeastern course of the Wind River and "along central Muddy Creek. The height of the terrace above Muddy Creek ranges from 140 feet in the western part to 175 feet in the eastern part and from 140 to 180 feet along the Wind River and Fivemile Creek. The thickness of the terrace gravel is 8 to 25 feet and the average thickness is about 14 feet. About 1 to 2 feet of finer material overlies the gravel.

Terrace T7 is present along the central and eastern course of Fivemile Creek as widely scattered remnants that are as much as half a mile wide; it also occurs to a very limited extent along the Wind River in T. 2 N., R. 5 E. Terrace T7 is highly dissected and is 220 to 240 feet above Fivemile Creek and the Wind River. Only a thin mantle of gravel and soil, 4 to 5 feet thick, caps these highly eroded remnants.

Terrace T8 is represented principally by three large remnants one at the extreme western end of the area and the other two in the western and east-central parts of Fivemile Creek valley but several smaller isolated remnants also are present along the Wind River. The eastern part of the largest remnant along western Fivemile Creek is highly dissected. This remnant consists of two surfaces, one about 20 feet lower than the other. These two levels are indicated, but not separated, on plate 1. The height of the terrace above Fivemile Creek ranges from about 375 feet in the western part to 300 feet in the eastern part and above the Wind River from 340 to 380 feet. The terrace gravel is 7 to 22 feet thick and is overlain by 1 to 2 feet of fine-grained material. This terrace, along western and east-central Fivemile Creek, and ter race T7, along eastern Fivemile Creek, constitute Indian Ridge (sometimes called Muddy Ridge), the natural divide between Five- mile and Muddy Creeks.

Terrace T9 is present only as isolated remnants in Tps. 1 and 2 N., R. 4 E., and in T. 2 N., R. 5 E. These remnants are highly dissected and are less than half a mile wide. They are 420 to 480 feet above the Wind River and are underlain by 6 to 18 feet of gravel and 1 to 2 feet of finer material.

Terrace TIO is present only along the Wind River. Several iso lated remnants from 1/2 to l l/2 miles wide are in Tps. 1 and 2 N., Rs. 2 and 4 E. The terrace is rather flat and fairly extensive, especially in T. 2 N., R. 4 E., where one remnant is about 2 miles long. The height of the terrace above the Wind River ranges from 500 to 550 feet. The gravel underlying the terrace is 7 to 18 feet thick and is overlain by 1 to 2 feet of finer material.

Terrace Tn occurs as a relatively flat and extensive series of connected remnants in Tps. 1 and 2 N., and Rs. 3 arid 4 E. The


series of remnants is about 6 miles long and i/g to 1^4 miles wide. Its height above the Wind River ranges from 580 to 620 feet. The terrace gravel ranges in thickness from 4 to 18 feet and is overlain by 1 to 2 feet of finer material.

The only remnant of terrace Tj2, in T. 1 N., R. 3 E., is about a mile long and half a mile wide. It is highly dissected, and its height above the Wind River is about 680 feet. The underlying gravel, which is 18 feet thick at the west end of the terrace, is mantled by about a foot of soil.

Terrace Ti3, which is represented by Lost Wells Butte (pi. 65), is the highest terrace in the area and is about 800 to 825 feet above the Wind River. Erosion has removed all but four very highly dissected remnants in T. 2 N., Rs. 3 and 4 E., all of which are less than one-eighth of a mile wide. These small remnants are under lain by a loosely cemented conglomerate containing cobbles as much as 8 inches in diameter. The thickness of the conglomerate ranges from about 4 to 10 feet.

A number of small terrace remnants border small arroyos in the interstream areas. Three terrace remnants along Antelope Gulch between Fivemile and Muddy Creeks, two remnants in T. 2 N., Rs. 1 and 2 E., southeast of Morton, and another somewhat larger remnant between Fivemile and Muddy Creeks at the extreme northwestern corner of the area have been mapped; however, the other remnants are too small to warrant mapping. Most of these remnants are less than a mile long and less than one-fourth of a mile wide. They range in height from 40 to 240 feet above the tributary drainages and are underlain by less than 5 feet of gravel.

Occurrence of ground water. Permanent bodies of ground water have developed within the lower terrace deposits along the Wind River in areas that have been irrigated for some time. These deposits now yield satisfactory water for domestic use.

In the terrace deposits that underlie the newly irrigated terraces T! and T2 in Tps. 2 and 3 N., R. 6 E., ground-water bodies are de veloping and apparently have become permanent after only two seasons of irrigation. Satisfactory water may be obtained from these deposits if irrigation is continued and drainage is good. If this source of supply is to be developed, the wells should be located a considerable distance from the outer terrace margin and deep enough to penetrate the full thickness of the terrace deposits. As the higher terraces along the Wind River are not irrigated at the present time and are not likely to be irrigated in the future be cause of their high altitude and relatively small areal extent, the gravel underlying these terraces is not likely to become a source of water supply.

ExceDt for a few small areas, the terraces along Fivemile and


Cottonwood Creeks are not irrigated at present nor is extensive irrigation planned for them in the near future. Probably little or no ground water has accumulated beneath these terrace remnants, as no springs issue from the base of the gravel along the terrace edges. Moreover, because most of the remnants are isolated and of small areal extent, it is unlikely that the application of irrigation water would result in the accumulation of significant supplies of ground water.

Irrigation of the Muddy Creek terraces was begun in 1951. Bodies of ground water are forming in the terrace deposits, and these will become permanent if irrigation is continued; after sev eral years, wells penetrating the terrace deposits probably will yield adequate quantities of water for domestic use. At first, the water probably will be highly mineralized, but eventually the qual ity of the water will become satisfactory if the soluble salts that have accumulated in the surficial deposits during long periods of aridity are leached out by continued infiltration of irrigation water and if the ground water is discharged from the area by springs along the slope at the terrace edges. On any terrace the best loca tion for a well is as far away as possible from the terrace margins and from any depressions or valleys. Wells that penetrate the full thickness of the terrace deposits are the most likely to en counter water.

Field observations do not indicate the presence of water in the gravel deposits underlying the small interstream terraces.

Drainage. Where the lower terraces along the Wind River have been irrigated for some time, waterlogging has occurred along or near the base of the slope between terraces, along the outer edge of the higher terrace, and in some places within the terraces. Water from irrigation infiltrates to the zone of saturation, percolates laterally toward the Wind River in a downvalley direction, and then is discharged at the lower, outer edge of the terrace. In some places the water is intercepted by drains that conduct the water to the bottom land or to the Wind River. In most places, however, the water is allowed to pass onto the next lower terrace, which be comes progressively waterlogged near its upper edge if more water is moving into the terrace deposits of this lower terrace than can be transmitted by the deposits. This situation is common where water is discharged at the terrace edges. However, the outer edge of the lower terraces along the Wind River generally is mantled by colluvial-alluvial debris, which greatly retards the discharge of water at the terrace margin. The surface of the terrace gravel also is covered locally with a considerable thickness of relatively impermeable fine-grained material. Because the discharge of


ground water from the terrace gravel is retarded, the water table rises and the capillary fringe above the water table extends to the land surface.

Where waterlogging occurs, evaporation of the ground water re sults in the deposition of salts in the soil, which in time may destroy the soil structure and decrease its permeability. Continued re charge in excess of the capacity of the terrace deposits to discharge the ground water creates a condition of almost permanent water logging. This has already occurred in parts of terrace T2 in the Riverton area, which has been irrigated for some time. The same condition also probably will develop after continued irrigation of the newly irrigated parts of terrace T 2 in Tps. 2 and 3 N., R 6 E. (Hidden Valley). In both areas the alluvial-colluvial mantle of terrace T2 is thick; at its northern extremity in T. 3 N., R. 6 E., the terrace is wholly obscured by the mantling deposits.

The most effective method of alleviating the poor drainage of terrace T2 would be the construction of interception drains at the outer edge of the terrace; the exposure in the drains of as much of the total thickness of gravel as possible would effect the maximum discharge of water from the gravel. Another effective method would be the construction within the terrace deposits of intercep tion drains perpendicular to the direction of ground-water flow and penetrating the full thickness of the gravel section. If de tailed study indicated that the water in the gravel was under hy drostatic pressure, similarly located shallow drains would serve the same purpose if within them a series of relief wells penetrating the full thickness of gravel were installed. The necessary spacing of the wells would have to be determined by means of aquifer tests in each area to be drained.

The lowering of pressure or, where water-table conditions exist, dewatering of the gravel by gravity drainage would effect drainage of the overlying soil. Although the soil is fine grained and would yield water very slowly, the large size of the contributing area and the increased hydraulic gradient would result in a lowering of the water table to a depth that would relieve the waterlogged condition of the soil. Chemical treatment of the soil to improve the struc ture and to increase the permeability then would be effective.

Except in areas where the soil has been dispersed by sodium salts and consequently should not be irrigated, the high permeabil ity of the surface materials mantling the Muddy Creek terraces necessitates the application of large amounts of irrigation water. Although the ynderlying terrace gravel seems to afford good sub surface drainage now after only a short period of irrigation, under certain conditions a high water table may develop in some parts of


the terraces, especially along and near the base of the slopes be tween terraces where bedrock is at or near the surface and also where sodium-dispersed soils may create a local perched water table. Unless intercepting drains prevent the ground water of a higher terrace from entering the next lower terrace, progressive waterlogging of the lower terrace near its upper edge may occur. This will be especially true if the water moving into the lower ter race cannot be carried away through these deposits as rapidly as it is discharged from the higher terrace. The problem of soil disper sion warrants thorough consideration, too, because it may be im possible or impractical to improve this condition.

Waterlogging may occur also in the colluvial-alluvial materials, which are less permeable than the terrace deposits and which com pletely mantle the slope between terraces in many places. If the flow of ground water from a higher to a lower terrace is retarded by colluvial-alluvial materials, the water table will rise to the surface near the contact of the colluvial-alluvial material.

As irrigation continues, the three channels crossing the divide between Muddy and Cottonwood Creeks will serve as natural ground-water and surface-water drains and may contain flowing water during part, if not all, of the year. Until these drains ad just to the new conditions of flow, erosion is likely to be a problem and measures to prevent gullying may be needed.

In the areas to be irrigated, if observation wells penetrating the entire thickness of the terrace deposits were installed at carefully selected sites, measurements of the water level in these wells would indicate at an early date any tendency toward high-water-table conditions. These observation wells should be installed along cross-valley profiles and along the outer and inner margins of each terrace; on wide terraces, observation wells should be installed also in the central areas. At least one line of wells should transect the eastern, central, and western parts of the terrace system; the line should cross where the terrace is widest.

Most of the excess irrigation water that is applied to terraces T3 to T6 probably could be intercepted by two drains. One, Cotton- wood drain, already has been constructed through the series of blowout depressions; the other should be constructed along the outer margin of terrace T3 and, throughout its length, should cut through the terrace deposits into the underlying bedrock. The feasibility of this second drain would depend on the location and character of the bedrock surface, which could be determined by test drilling. The large depression in the southeast part of T. 4 N., R. 5 E., which now is an outlet for Cottonwood drain, could also serve as an outlet for the proposed drain.


The terraces along Fivemile and Cottonwood Creeks are similar to those along Muddy Creek. However, because the individual terraces likely to be irrigated are isolated and exposed, drainage problems are not imminent in these two areas.

Owing to their very limited areal extent, neither the small interstream terraces nor the other small terrace remnants are likely to be irrigated and, hence, are unlikely to present drainage problems.

COLLUVIAL-ALLUVIAL DEPOSITS, UNDIFFERENTIATED

Mixed colluvial-alluvial deposits mantle the Wind River forma tion throughout most of the area. As it is impossible to delineate these deposits without very detailed study, they do not appear on plate 1. The areal extent and character of these deposits, however, are described in the following paragraphs.

Areal extent. Deposits of colluvium and alluvium mantle many of the scarps between .terraces and most of the broad bedrock slopes, or pediments, that flank the terraces and buttes throughout the area.

Description. Both colluvium and alluvium consist of material derived from the weathering of rocks. Colluvial material, typi cally formed in an arid climate, moves principally by gravity from its place of origin to its place of deposition and, in the Riverton area, it mantles the terrace scarps or slopes at the base of terraces or buttes in the form of diversified rock debris. Typically un- sorted, the colluvium contains particles that range in size from silt to boulders. The alluvial part consists of sand, silt, and clay, which mantle terrace scarps and the bedrock slopes at the base of terraces and buttes, and which have been transported principally by running water but for only short distances. The alluvium occurs also as fans that spread out over the slopes and coalesce in places to form flat surfaces contiguous with alluvial deposits underlying the bottom land. These alluvial deposits are fairly well sorted and grade from coarse to fine particles with greater distance from the parent source.

In most places where they are present the colluvial-alluvial de posits generally are 5 to 10 feet thick. However, locally greater sedimentation has occurred either because the material was depos ited in a small basin or the adjacent contributing area was large or because of the alluviation of buried channels of older drainages that passed through the locality. In the central part of Paradise Valley, T. 2 N., R. 4 E., and the northeastern part of the North Pavillion area, T. 4 N., R. 2 E., for instance, thicknesses of more than 20 feet of colluvial-alluvial deposits have been reported. Fan deposits up to 70 feet in thickness have already been described in


the discussion of terrace T2 (see p. 28).Formation of the colluvial-alluvial deposits involved relatively

little action by running water; consequently, the deposits in many places are not stable when saturated. As a result, when irrigation water is first applied to the relatively thick, fine-grained deposits, compaction and settlement occur in proportion to the total thick ness of the deposits. Since irrigation water was first applied in the North Pavillion area settlement in sec. 36, T. 4 N., R. 2 E., has reached a total of more than 5 feet. This settlement is the greatest that has occurred in the Riverton area and probably is due to the relatively great thicknesses of colluvial-alluvial deposits in the buried drainage channels underlying that locality.

Occurrence of ground water. The colluvial-alluvial deposits are relatively impermeable and lack uniformity in thickness and lateral extent. However, appreciable quantities of water accumulate in those parts of the area that have been irrigated for several years. The yield of wells tapping these deposits is inadequate for domestic use, and unless the colluvial-alluvial deposits are recharged directly by canal seepage, the water is not satisfactory for domestic use nor is it likely to improve significantly.

Drainage. The low average permeability of the colluvial- alluvial deposits and of the underlying bedrock make it certain that drainage problems will arise. The problems will be spotty because of the variation in the thickness and lateral extent of the deposits and of their heterogeneity. In some areas little or no colluvial- alluvial material overlies the bedrock, whereas in other areas a considerable thickness is present. The change in thickness gen erally is progressive, but in some places it is abrupt as, for exam ple, in the vicinity of older drainage courses that have been alluviated.

Inasmuch as these colluvial-alluvial deposits include material transported both by soil creep and by running water, they are characterized by a wide variation in the sorting and size of par ticles. The lack of homogeneity causes differences in the permea bility of the deposits. Although the permeability of transported materials generally decreases with increasing distance from their source, impermeable materials are present in many places without respect to distance from the source. In places the permeability of the deposits has been reduced as a result of their high salt content, particularly the high sodium content. Differences in the permea bility are important because they necessitate differences in the depth and spacing of ditches if drainage is to be effective.

Another variable to be considered is the underlying bedrock formed by the Wind River formation. Because the bedrock sur-

GEOLOGIC FORMATIONS AND THEIE WATER-BEARING PROPERTIES 37

face ranges from gently sloping to undulating and irregular, the overlying surficial deposits are irregular in thickness. In addi tion, the permeability of the bedrock is low, but somewhat variable. Water moves into the Wind River formation through fractures and the more permeable zones, but the movement is slow. These fac tors greatly influence the drainage of the overlying deposits. As pointed out previously, in some places the surficial deposits may be recharged by leakage from underlying confined aquifers in the Wind River formation.

Because of the above characteristics of the colluvial-alluvial ma terial and the underlying bedrock, waterlogging has occurred or will occur where (1) the colluvial-alluvial deposits thin or wedge out and thus force water to the surface; (2) a local irregularity or an abrupt change in slope of the underlying bedrock surface re duces the cross-sectional area through which the water can move; (3) the permeability of the surficial deposits and the underlying bedrock is so low that discharge from the deposits is less than re charge to them; and (4) artesian water from the underlying Wind River formation rises and enters the surficial deposits.

As the above conditions, either singly or in combination, exist in much of the area covered by the colluvial-alluvial deposits, drain age problems have developed or are likely to develop in such areas as the newly irrigated North Portal area in Tps. 3 and 4 N., Rs. 2 and 3 E. In order to foretell any tendency toward waterlogging, observation wells penetrating the full thickness of the colluvial- alluvial material mantling bedrock should be installed along two or three cross-valley lines. In the areas already waterlogged there is some question whether drainage is economically feasible. Rigid control of water use should be exercised in all areas mantled by colluvial-alluvial deposits, and measures should be taken to reduce seepage of water from canals. A detailed study of the hydrology and geology of each affected area should be made before corrective measures are attempted.

Detailed geologic and hydrologic studies, with special emphasis on the origin and nature of the surficial deposits and underlying bedrock formations, should be made in all areas of colluvial-alluvial deposits that are considered for future irrigation. The factors re lated to drainage perhaps are more important than any others in determining whether a given tract is suitable for irrigation; thus, these investigations logically should precede any others proposed to evaluate the land for agriculture. Certainly, any plan for the future agricultural utilization of areas of bedrock mantled by colluvial-alluvial deposits should be undertaken only after due con sideration of the nature of these materials and their drainability.


ALLUVIAL DEPOSITS

Alluvial deposits occur as valley fill along the principal streams and their tributaries.

Areal extent. The alluvial deposits are most extensive along the Wind River where they are commonly a mile or more wide. Along Fivemile, Muddy, and Cottonwood Creeks they generally range in width from less than a quarter of a mile to about three- quarters of a mile, but in places they are as much as a mile wide. The width of the bottom land along each drainage course is rela tively uniform, with certain exceptions: the alluvial deposits along the Wind River are narrower than average near the west flank of the Pilot Butte anticline, and the alluvial deposits along Fivemile and Muddy Creeks are somewhat irregular in width and more extensive in the east-central and eastern reaches than along the upper reaches of the creeks.

Alluvial deposits are present along the numerous small tribu taries to the principal streams, but their areal extent is too small to warrant mapping. Consequently, only the more extensive allu vial deposits are shown on plate 1.

Description. The alluvium consists mostly of sand, silt, and clay, but in some places it contains considerable coarse sand and gravel.

The thickness of alluvium along the principal streams ranges from a featheredge to about 67 feet. The Bureau of Reclamation has reported a maximum thickness of 67 feet along Fivemile Creek and a maximum thickness of 35 feet along Muddy Creek. The logs of numerous test holes and water wells indicate that along Five- mile Creek the average thickness of the alluvium is about 40 feet and along Muddy Creek about 30 feet. The thickness of the allu vium along the Wind River and Cottonwood Creek is not known, but it probably is about the same as that along the other principal drainage courses in the area.

The alluvial deposits, especially those along the Wind River, Muddy Creek, and upper Fivemile Creek, contain a large propor tion of gravel. The deposits along Muddy Creek are reported by the Bureau of Reclamation to be remarkably uniform; about 10 feet of gravel was cored below stream level. It is estimated that the alluvial deposits along upper Fivemile Creek contain about 10 feet of gravel.

The alluvial deposits along small tributary drainages of the area were not studied in detail. Although of local origin and less thick, they probably are similar to the deposits of the principal streams.

Occurrence of ground water. The lower part of the alluvial de-


posits bordering the Wind River contains a permanent body of ground water, which probably is due to recharge both from irriga tion and the Wind River. Although this aquifer has not been utilized extensively for water supply, dug wells in some places yield water that is suitable for domestic, stock, or irrigation use. The old Shoshone town well, on the east side of the Wind River in sec. 16, T. 3 N., R. 6 E., and soon to be flooded by water in Boysen Reservoir, provided a hard water used for municipal supply. Three interconnected dug wells in the same area have also provided an adequate quantity of water suitable for irrigation. The quality of water in the alluvium along the Wind River seems to depend on the source of recharge. In areas where alluvium and adjacent de posits are not irrigated and where the Wind River is the principal source of recharge, the quality of water is satisfactory for domestic use. Conversely, in areas where the recharge is principally from irrigation and where ground water is being discharged into the Wind River, the water generally is highly mineralized and suitable only for stock use. In such areas the pumping of ground water from wells located near the Wind River probably would induce re charge directly from the river and thus improve the quality of the water.

The alluvial deposits along Fivemile, Muddy, and Cottonwood Creeks contained some ground water before these lands were irri gated, but owing to subsequent irrigation along portions of the creeks, considerable water locally has been added to storage and the water table has risen. The creeks in these areas have become or are becoming effluent; that is, they are receiving water from the zone of saturation. A good example of this is Fivemile Creek, along which the water table has risen owing to the extensive irriga tion of adjacent alluvial and other deposits. As the water in Five- mile Creek, probably also in Muddy and Cottonwood Creeks, is highly mineralized, the water in the alluvial deposits along these creeks is likely to be unsatisfactory for domestic use.

Drainage. The alluvial bottom land is waterlogged in many places along the Wind River, especially in the eastern part of the report area. The waterlogging is caused (1) by infiltration of irrigation water applied to the alluvial and adjacent colluvial- alluvial deposits, (2) by uncontrolled return flow from irrigation higher terraces, or (3) by ground water discharged from higher terrace deposits. In many places the alluvial deposits are rela tively impermeable and the hydraulic gradient is low. The relative impermeability is due in part to the presence of very fine grained materials in the upper part of the alluvium, and in part to dispersal of the soil by sodium in the infiltrating water. The hy-


draulic gradient of the water table to the Wind River is low because of the width of the deposits and the shallowness of the Wind River channel. The water table rises, but the rise is insufficient to in crease the hydraulic gradient to the point that the discharge equals recharge. Thus, excess irrigation water either accumulates in topographic depressions or, by contributing to ground-water stor age, causes the water table to rise close to the land surface. As a result, long-continued evaporation of the water has left a heavy accumulation of salts in the soil, and the alluvium has become pro gressively more impermeable and the waterlogging more extensive. In areas where the principal source of recharge to the alluvium is from higher lying terraces, the problem of waterlogging could be solved in part by constructing drains along the terrace edges. The drains should be incised to bedrock throughout their length. Interception of surface-water runoff from the terraces also would help and, in addition, would improve the drainage of-the terraces themselves. In some areas where waterlogging is caused solely by seepage of irrigation water applied to the alluvium and adjacent colluvial-alluvial deposits, the waterlogging could be remedied or alleviated by more careful application of irrigation water.

Irrigation along Muddy and Cottonwood Creeks has not been practiced long enough to cause much waterlogging of the alluvial deposits. However, in small areas along the middle and lower reaches of Fivemile Creek, some waterlogging has occurred, mainly as a result of irrigation of the alluvium and adjacent colluvial- alluvial deposits. Although some improvement has resulted from the construction of open drains through some of the waterlogged areas, these areas probably will be difficult to maintain in a condi tion suitable for extensive agriculture. If waterlogging in these areas is to be prevented or remedied, the amount of irrigation water applied to the land must be rigidly controlled.

EOLIAN DEPOSITS

Areal extent. Eolian deposits are present throughout the area, especially along the streams and in areas adjacent to badlands and steep escarpments; they are more common along Muddy and Cot tonwood Creeks. The areal extent of eolian deposits can be accu rately mapped only by very detailed work; for this reason, only the larger accumulations of eolian sand are shown on plate 1.

Description. Eolian deposits consist mostly of sand and silt. These are deposited wherever the sand-laden wind encounters land forms or vegetation that decrease its velocity and carrying ability. The deposits accumulate and sometimes form hummocks and dunes. If the wind is steady and blows mostly from one direction, bar-


chans, or crescentic sand dunes, are formed. A well-developed active barchan in sec. 18, T. 4 N., R. 6 E., indicates a wind direction from the southeast. Dunes are the most obvious eolian deposits; however, a large part of the area is mantled by a thin deposit of eolian material.

Occurrence of ground water. The eolian materials are not im portant as ground-water reservoirs. They are mostly of fair to high permeability, however, and so may be effective in some places in absorbing rainwater and transmitting it to underlying deposits.

PLAYA DEPOSITS

Areal extent. Playa deposits are present in the lower parts of the larger closed depressions between Muddy and Cottonwood Creeks.

Description. During periods of heavy precipitation, silt- and clay-laden inflow spreads over the floor of a depression and forms a playa lake. Evaporation between periods of inflow leaves a thin layer of fine-grained material, some of which is later removed or redistributed by wind action. In some of the depressions in this part of the area the playa deposits are about 2 to 3 feet thick. Their relative impermeability causes ponding and retention of water in the depressions.

Occurrence of ground water. Playa deposits generally contain water only during and shortly after the wet seasons. Cottonwood drain, which now interconnects the series of depressions along an old channel through Muddy Creek terraces in T. 4 N., Rs. 4 and 5 E., will prevent the accumulation of water in some of these depres sions. The playa deposits will then receive little water except by effluent seepage after irrigation is begun on adjacent terraces.

GROUND WATER

DEPTH TO WATER TABLE

The depth to water in a well is a measure of the depth either to the water table in an unconfined aquifer or to the piezometric, or pressure, surface of water in a confined aquifer.

Precipitation that is not evaporated, absorbed by the soil and later transpired by vegetation, or carried away as surface runoff infiltrates to the zone of saturation. In some places, a perched ground-water body may be formed above the main water table; the sediments between the perched water body and the main water table are not saturated. The water table rises when recharge to ground-water storage exceeds discharge and declines when dis charge exceeds recharge. In the Riverton area the water table


rises in response to recharge from irrigation water and declines during the nonirrigation season. Consequently, unless made at approximately the same time of year, measurements of the depth to water in any well are not indicative of changes in the long-term recharge-discharge ratio.

A map (pi. 2) showing the depth to the water table during Au gust 1950 was prepared for the Midvale and North Pavillion areas of the Riverton project. This map shows that the depth to water in unconfined aquifers ranges from less than 1 foot to more than 30 feet below the land surface. Because the configuration of the water table is similar to, but more regular than, the general surface topography, pronounced variations in the depth to water are caused primarily by irregularities of the land surface. Local perched water bodies and local differences in permeability and per colation rate also affect the shape of the water table. The map shows the effect of irrigation on depth to water. In the newly irrigated areas, such as the Lost Wells area and the North Pavillion area (see fig. 2), after 1 to 2 years of irrigation, the depth to water is still generally greater than 10 feet. However, direct recharge from irrigation canals and laterals already has caused the depth to water near canals to decrease to less than 10 feet. Continued irri gation will cause a further rise of the water table, and in a pro gressively larger area the depth to water will be less than 10 feet. Various stages in the sequence of events are shown by the depth to water in the remaining areas on the map (pi. 2) where irrigation has been practiced for some time. In a great percentage of these areas the depth to water is less than 10 feet. In some materials the capillary fringe above the water table extends to or nearly to the land surface and drainage problems exist.

If waterlogging is to be prevented in other parts of the area, rigid control of water use and the elimination of great losses of water by influent seepage from canals and laterals will be essen tial. If corrective measures to limit recharge from irrigation water are applied, it is suggested that periodic maps of the depth to water be made. These would aid in the evaluation of the effec tiveness of the corrective measures. The rise of the water table in newly irrigated areas should be observed carefully as irrigation is continued.

DEPTH TO PIEZOMETRIC SURFACE

Under artesian conditions water moves into the interconnected sandstone lenses within the Wind River formation either directly from the zone of saturation or through permeable zones and frac tures in the relatively impermeable confining beds. Because the

GROUND WATER 43

water is confined, its upward pressure against the confining bed is equivalent to the head resulting from the difference between the altitude of that point and the altitude of the water table in the re charge area minus the loss of head due to friction of movement. So long as the rate of recharge and discharge are constant, there is little relief for this pressure except where wells penetrate the aquifer or where leakage occurs. The water level in a well that penetrates the aquifer stands at a height abov_e the top of the con fining beds equivalent to the pressure head at that point. The imaginary surface to which water from an artesian aquifer would rise under the full pressure head is called the piezometric surface. In heterogeneous aquifers, such as the Wind River formation, however, the height to which water from a given standstone bed will rise in wells corresponds to the pressure head of the water confined in that sandstone at the point penetrated by the well.

At depth the Wind River formation in the report area comprises at least two distinct zones, both of which contain interconnected water-bearing sandstone lenses. The exact relation of these zones to each other is not known, but apparently they can be identified by the depth to water in wells; that is, the water in the upper sand stones of the Wind River formation rises to one piezometric sur face and the water in the deeper sandstones rises to another. These relationships cannot be resolved definitely without much more information about deep wells than is now available.

WATER-LEVEL FLUCTUATIONS

The stage of the water table or piezometric surface is a measure of the amount of water in underground storage; a rise of the water level indicates a gain of water in storage and a decline indicates a loss from storage. In wells tapping unconfined aquifers in this area, the water levels fluctuate mainly in response to recharge from irrigation and to discharge by evapotranspiration and natural drainage; the magnitude of these fluctuations is, of course, greatest in wells nearest sources of recharge or points of natural discharge. In wells tapping confined aquifers, the water level fluctuates in response to the increases or decreases in hydraulic head that result from the withdrawal of water from wells and to differences in the rates of recharge and discharge, and, to a minor degree, in re sponse to changes in barometric pressure. If recharge and dis charge are constant and the rate of withdrawal is small, the water level fluctuates very little throughout the year; this is the usual condition in the deeper confined aquifers of this area. If recharge and discharge vary substantially even though the withdrawals are


small, the water level fluctuates considerably; this is the usual condition in the shallower confined aquifers recharged by irrigation.

In order to determine the type and magnitude of water-level fluctuations in the aquifers of the report area, 32 wells were se lected early in the investigation for monthly measurement of the water level. The number of wells has changed from time to time and as many as 109 wells have been measured. In addition, re cording gages have been maintained on six wells (Al-4-29bd2, Al-4-33dd, A2-3-35cal, A2-5~6adl, A3-2-£Ocdl, and A3-2- 27abl) in strategic locations. Most of the observation wells tap water that is under water-table conditions, but several tap confined

Graphs showing the fluctuations of the water level in wells tap ping water under water-table, shallow-artesian, and deep-artesian conditions were prepared from daily noon readings of the water- level recording gages. The fluctuations of the water level in wells A2-3-35cal and A2-5-6adl, both of which are "water-table" wells, show the effect of recharge from irrigation. (See fig. 7.) Well A2-3-35cal is near the Pilot canal, and well A2-5-6adl is near a lateral fed by the Pilot canal. The somewhat later rise of the water level in well A2-5-6adl probably is due to its distance down stream from well A2-3-35cal. Also, well A2-5-6adl is close to

GROUND WATER 45

a natural drain, which may account for the somewhat greater fluctuation of the water level in this well. The water level in both wells responds to recharge from irrigation; the water level gen erally rises throughout the irrigation season and falls throughout the nonirrigation season. The short-lived drop of water level, which is shown by the hydrographs to have occurred directly after water was turned into the canals, is thought to be a natural decline of water level before the recharge from irrigation was effective. The water level in well A2 5 6adl, which is in an area that re ceives recharge both by seepage from a lateral and by infiltration of applied irrigation water, began to decline about a month before the end of the irrigation season. This decline is explained by the lesser amount of water being carried by the laterals and the cor-

respondingly lesser amount of irrigation water being applied. The water level in well A2-3-35cal, which is in an area where the recharge is principally from the main canal, did not begin to de cline until the canal no longer carried water.

The hydrographs of the water level in these two wells show, in general, the trend of water-table fluctuations throughout the River- ton project area and adjacent irrigated lands.

Because seepage from irrigation recharges the shallow artesian aquifer and because the withdrawal of water from the aquifer is small, the water level in well A3-2-20cdl, which taps this aquifer, responds primarily to the increase or decrease in pressure resulting from irrigation recharge. (See fig. 8.) The prompt rise or fall of the water level when irrigation water is turned into or from the canals indicates that the hydraulic pressure in the aquifer


varies directly with the amount of recharge from irrigation. The minor fluctuations in the well are due to changes in barometric pressure.

Wells Al-4-33dd and Al-4-29bd2, which are near Riverton, are deep artesian wells. As recharge to and discharge from the aquifer tapped by these wells is relatively constant and as the withdrawal of water is the principal means by which hydraulic pressure in the aquifer is relieved, the water level in the wells fluctuates in response to the changes in pressure that result from the pumping of wells concentrated in the area. (See fig. 9.) Well Al-4-33dd is within the radius of influence of the Riverton city

wells. During August, when pumping is the heaviest, the water level in this well drops to more than 80 feet below the land surface. During the winter months, when demands for water are less, the water level rises to about 30 feet below the land surface. The water level in well Al-4-29bd2, which is farther from the River- ton pumping wells, also is lowest during August, but the difference, between the August and winter water levels amounts to only about 6 feet. Both these wells provide an excellent record of the effect of large withdrawals of water from an artesian aquifer that is constantly being recharged.

In order to determine the long-term trend in storage, the meas urement of water levels in the observation wells should be con tinued. By comparing the water levels of successive years with the earliest water-level records, current conditions within the aqui fers can be evaluated.

GROUND WATER 47

RECHARGE

In the Riverton area recharge to the ground-water reservoir is from precipitation, irrigation, and surface-water infiltration.

PRECIPITATION

In comparison with the other sources of recharge, precipitation is not an important direct source of ground-water recharge in this area. The precipitation generally is rapidly absorbed by the soil or is evaporated directly from the surface. Only a small fraction, if any, of the water in the soil zone filters through the zone of aera tion to the zone of saturation. This is indicated by the presence of caliche in the soil zone and by the absence of a shallow zone of saturation in dryland areas before they are irrigated. The caliche, which is a foot or more thick in some places, is an accumulation of mineral matter resulting from evaporation of soil moisture de rived from precipitation; if water moved downward from the soil zone in large quantities, the caliche would not have formed. If precipitation were an important source of ground-water recharge, at least a thin zone of saturation would exist in most areas prior to irrigation.

A comparison of the hydrographs of the water level in two shallow wells in irrigated tracts with the daily record of precipita tion during the same period (fig. 7) indicates that precipitation usually causes no change in the water level. Fluctuations of the water level in wells at times of heavy precipitation during the nonirrigation season are minor; actually, it is not known whether the fluctuations are attributable to precipitation or to other causes. During the irrigation season, any water-level fluctuations caused by precipitation are obscured by the much greater fluctuations due to recharge from irrigation.

IRRIGATION

Recharge to the ground-water reservoirs in the Riverton area occurs mainly by influent seepage from irrigation canals, laterals, and reservoirs and by infiltration of water applied to cultivated land. Irrigation in the Riverton area is a large-scale and effective water-spreading operation comparable with that in areas where water spreading is practiced as a method of artificial recharge. The area is traversed by an elaborate system of canals and laterals, many of which are situated in relatively permeable surficial depos its. Also, water is stored the entire year in Pilot Butte Reservoir and Ocean Lake. Considerable water seeps from the reservoirs and from the ditches in transit to the farms of the area; personnel


of the Bureau of Reclamation report that only about 50 percent of the water diverted for the Riverton project actually reaches culti vated land. The loss of water in this area is of major importance. Not only is less water available for irrigation, but the large amount of water infiltrating the surficial deposits causes waterlogging in many places. Many canals and laterals, especially where incised into very permeable material, have been or are being lined to pre vent further loss of water. Because the amount of irrigation water applied often is in excess of crop needs and because the soil is highly permeable in some places, such as on the terraces north of Muddy Creek, much of the irrigation water sinks into the soil and is transmitted downward to the zone of saturation. Preliminary figures of the Surface Water Branch of the Geological Survey indi cate that 100,000 to 150,000 acre-feet of irrigation water is lost annually in the Riverton irrigation project by infiltration to the ground-water reservoir, evaporation, and transpiration. No at tempt has been made to determine the amount of water contributed to the ground-water reservoir in this area because the amounts discharged by evaporation and transpiration are difficult to establish.

The seasonal influence of irrigation on the amount of water in storage is shown by a study of the hydrographs of the water level in two "water-table" wells situated in cultivated areas and near irrigation canals or laterals. (See fig. 7.) The water level in both wells began to rise steadily about a week after water was turned into the canals and laterals and fell gradually after the flow in the canals ceased. Although the rise of the water level in wells during the irrigation season indicates to some extent the amount of water that is added to ground-water storage as a result of re charge from irrigation, it does not in itself show the total increase because discharge from the ground-water reservoir is progressing at the same time as recharge; the rise of the water level indicates only that the recharge exceeded the discharge.

The importance of irrigation as a source of recharge is empha sized by the rapidity with which a zone of saturation develops and by the rapid rise of the water level in newly irrigated areas. In parts of the North Pavillion area, in Tps. 3 and 4 N., Rs. 1-3 E., recharge from irrigation caused waterlogging in only 1 year.

Water is contributed to the ground-water reservoir by streams crossing areas where the water table is below the level of the stream; such streams are said to be influent. Data pertaining to the loss of streamflow from Muddy Creek have been compiled by the Surface Water Branch of the Geological Survey. During Sep tember 1949 the measured loss of water within the Riverton irri-

GROUND WATER 49

gation project was about 113 cfs. During the same month a flash flood increased the normal flow of Muddy Creek by 100 cfs where the creek entered the project area, but no increase in flow was noted at the lower end of the project. These data demonstrate that streamflow in influent stretches contributes considerable water to ground-water storage. The extent of the contribution by streams other than Muddy Creek, however, is unknown.

MOVEMENT

Ground water in a permeable material moves from one place to another if there is a hydraulic gradient (difference in head) be tween the two places. Ground water generally is in motion; truly stagnant ground water, or at least stagnant fresh water, is rare if it exists at all. Unconfined ground water moves in permeable rock that is underlain by relatively impermeable rock; confined water moves in permeable rock that is both underlain and overlain by relatively impermeable rock. In either situation, ground water moves from a place of recharge to a place of discharge at lower altitude. Although the rate of ground-water movement is affected by the texture and structure of the rocks, the direction of move ment always coincides with the path of least resistance to flow. Ground water generally moves so slowly that the internal friction of its particles is relatively low and its flow is "laminar" or "viscous."

According to Darcy's law the rate of movement of ground water is directly proportional to the hydraulic gradient and the permea bility, and the quantity of water discharged in a unit of time depends on the rate of movement and the cross-sectional area through which the water is moving.

The configuration of both the water table and the piezometric (pressure) surface can be shown on maps by contour lines. As water moves in the direction of the greatest slope of the water table or piezometric surface, the direction of movement is perpen dicular to the contour lines. The maximum difference in hydro static pressure is at right angles to the contour lines, and the slope or hydraulic gradient is measured along the line of maximum difference.

UNCONFINED AQUIFERS

In much of the Riverton area the colluvial-alluvial, alluvial, and terrace deposits together constitute the principal shallow aquifer and the water in them generally in unconfined. Because the re charge is considerable during the irrigation season, tho water table rises and discharge increases somewhat. The slow decline of the


water levels after the irrigation season (fig. 7) indicates that ground-water movement is slow. Nevertheless, because the surficial deposits are recharged directly by irrigation water, the quan tity of water passing through them is comparatively large.

The direction of movement of ground water in the surficial de posits is generally the same as the slope of the land surface. For example, in inter-butte areas, ground water moves downgradient through the colluvial-alluvial deposits either toward some ephem eral wash or toward the center of a closed basin. In terrace areas ground water moves in a downvalley direction through the terrace deposits toward the principal surface drainage. In valley allu vium, water moves in a downvalley direction as underflow parallel to streamflow. Although the topography of the land surface gen erally is a key to ground-water movement in the surficial deposits of the area, the irregularities of the underlying bedrock surface locally modify and complicate the direction of movement.

To illustrate these characteristics of shallow ground-water movement in unconfined aquifers in the Riverton area, a general ized map of the Midvale area of the Riverton irrigation project was prepared from data in the files of the Bureau of Reclamation. (See pi. 3.) This map shows the position of the water-table con tours immediately before the 1950 irrigation season (about March 15) and during the latter part of the irrigation season (August 15), and thus approximately represents the low and high water levels during the year. The relative rates of movement are indi cated by the spacing between the water-table contours for March and August. If the contours are closely spaced or if the March contour crosses the August contour line (thus showing higher water levels), the movement of ground water evidently is slow. Conversely, if the contours are more widely separated, the move ment of ground water evidently is more rapid. The entire Mid- vale is mantled primarily by colluvial-alluvial deposits that receive direct recharge from irrigation.

CONFINED AQUIFERS

In the Riverton area, ground water in the Wind River formation generally is confined under artesian pressure. The water level in a well that penetrates one of the systems of essentially horizontal lenticular water-bearing sandstones in the Wind River formation coincides with the piezometric surface of that system. At least two major water-bearing zones and two piezometric surfaces are known to be present in the Riverton area, but insufficient data are available for the precise depiction of these surfaces. The response of the water level in observation wells to the pumping of ground

GROUND WATER 51

water during an aquifer test in the Riverton well field indicates that the sandstone lenses within a certain depth range are inter connected hydraulically and that the formation within this depth range reacts as a hydraulic unit. Although the mode of intercon nection of the sandstone lenses is unknown, it is assumed to be largely by fractures in the impermeable materials separating them.

DISCHARGE

In the Riverton area, ground water is discharged by evapotranspiration; into streams, drains, and lakes; and through wells and springs. Some ground water is discharged from the area as underflow in the alluvium of some of the creeks.

EVAPOTRANSPIRATION

The loss of soil moisture and ground water by evaporation is greatest during the summer when the temperature is highest and where the water table or capillary fringe extends to the land sur face. Inasmuch as the periods of high temperature coincide with the periods of high water table resulting from the application of large amounts of irrigation water, much water is evaporated and an accumulation of salts is left on or near the land surface.

The loss of soil moisture and ground water by transpiration of plants is also greatest during the growing season owing to higher temperatures and large applications of irrigation water. Quanti tatively, however, the transpiration of soil moisture is much more important than the transpiration of ground water, despite the fact that phreatophytes derive most of their water supply from the zone of saturation or capillary fringe.

Although the total discharge of ground water by evaporation and transpiration is quantitatively important, it probably is small compared with other types of ground-water discharge. It is of economic importance, however, because much of the ground water discharged in this manner is wasted or produces plants that have little or no value.

STREAMS AND DRAINS

Most of the ground water discharged from unconfined aquifers and some of the water discharged from confined aquifers leaves the Riverton area in streams and open drains and eventually flows into the Wind River.

Wherever a stream is incised below the water table in surficial deposits, ground water discharges into the stream. For example, the average base flow of Fivemile Creek, which is about 38 cfs in


the winter season, represents essentially the total inflow of ground water into the creek and its tributaries. During the irrigation sea son, when the increased recharge causes a higher water table and a correspondingly steeper hydraulic gradient to the creek, the dis charge into the creek is greater. Some shallow confined water in the Wind River formation also is released to streamflow, especially where lower Fivemile Creek is incised into the formation.

Similarly, where the water table is higher than the floor of an open drain, ground water is discharged into the drain. However, the efficiency of a drain as an agent of ground-water discharge depends on the course of the drain with respect to the direction of ground-water flow, the elevation of the water table with respect to the floor of the drain, and the permeability of the material trans mitting the water. If a drain is perpendicular to the direction of ground-water movement, it will intercept the maximum amount of ground-water flow; and the greater the depth of a drain below the water table, the larger the amount of ground water discharged into it. However, even though a drain is perpendicular to the di rection of ground-water movement and is incised well below the water table, it will not be effective if the water-bearing materials are relatively impermeable.

In many parts of the Riverton irrigation project the permeability of the waterlogged material is low because of a high content of sodium salts or because of fine-grained texture, and, although the hydraulic gradient is steep, the drains are ineffective except for short distances on either side. The low permeability of the water logged material is the principal obstacle to drainage of many waterlogged areas within the Riverton project.

LAKES

The total inflow of ground water into topographic depressions has contributed to the formation of lakes in some parts of this area. Discharge occurs directly when the elevation of the water table is greater than the elevation of the lake surface and indirectly when ground water discharges to open drains flowing into the lake. The lakes are formed only where the surficial deposits transmit water into the depressions and tributary open drains faster than it can be evaporated. As the bottom of such a depression generally is bedrock of low permeability, the ground-water discharge, along with some return flow from irrigation, accumulates in the depres sion and remains throughout the year. Effluent ground water is known to be the primary source of recharge to the lakes because, after irrigation return flow has ceased, a relatively constant water level in the lakes is maintained even though water is discharged

GROUND WATER 53

from the natural or artificial outlets of the lakes. Ocean Lake, which has existed only since the beginning of irrigation in this area, is a notable result of total ground- and surface-water inflow.

WELLS AND SPRINGS

Most wells in the report area penetrate zones of confined water in the Wind River formation. Although some along the Wind River are flowing wells, elsewhere in the area a pump generally is needed to lift the water to the surface. A few wells tap the ter race deposits or alluvium, but their total yield is small compared to that of wells tapping the Wind River formation. Springs issue from the terrace and alluvial deposits along the Wind River and other drainages, especially where these deposits are irrigated or are adjacent to irrigated land.

The locations of wells and springs in the Riverton area are shown on plate 1, and data pertaining to them are given in table 18.

AQUIFER TEST OF WIND RIVER FORMATION AT RIVERTON

The rapid increase in the population of Riverton during the period 1930-50 greatly increased the demand far water. When additional wells were installed, however, it soon became apparent that the supply of ground water in the vicinity of Riverton was limited. Accordingly, an aquifer test was run to obtain informa tion on the water-bearing properties of the Wind River formation. The well numbers used in describing the aquifer test correspond, as follows, to the coordinate numbers used elsewhere in the report:

35bbl34ad27dd27dc27cdl

Well 7.............Al-4-34bal8............. 34bb29............. 34bbl

10............. 34ca11............. 33dd

Construction records and logs of all wells used in the test are given in tables 17 and 18; with the exception of well 11, all are owned by the city of Riverton.

TEST PROCEDURE

A time of year was selected when a minimum number of wells could supply the daily municipal demand. Well 8 (fig. 10) was selected as the well to be pumped during the test because it was centrally located and its rate of pumping could be controlled so as


Dashed circle is locus of image of well 4; all others are of well 8

R.4 E.

FIGURE 10. Map showing location of municipal wells used in pumping test and circles whose radii are equal to the computed distance to the image well.

to produce fluctuations in the water level of nearby observation wells. After the daily municipal demand had been estimated, wells 2, 3, and 4 on the east side of the city well field were selected for continuous pumping to meet that demand for the duration of the test. Arrangements were made for the disposal of all excess water so that the discharge for supply purposes could be main tained at a constant rate.

The schedule of pumping in the Riverton well field prior to March 13 was not recorded. During the daytime of March 13 only well 8 was pumping, and that evening well 8 was shut off and the pumping of wells 3 and 4 was begun. Because the demand for water during the test period was expected to exceed the yield of wells 3 and 4, the pumping of well 2 was begun on the morning of March 14. Measurements of the water level in the wells to be used during the test were made at intervals for the remainder of

GROUND WATER 55

FIGURE 11. Hydrographs showing the recovery of the water level in wells 5 to 11 prior tobeginning of test.

that day and on the following 2 days. By March 16 the water level in all the wells was recovering at a similar rate. (See fig. 11.) One observer was assigned to each observation well.

The starting of the pump on well 8 at 10:80 a. m. on March 17 marked the beginning of the drawdown test. During the test the pumping of well 8 was regulated at an average rate of 200 gpm and measurements of the water level in each observation well were


made at frequent intervals. At 1:47 p. m. on March 19, after well 8 had been pumped for about 51 hours, the pumping of well 4, which was yielding at an average rate of 190 gpm, was discon tinued, but the pumping of well 8 was continued as before. The stopping of the pumping of well 4 marked the beginning of the recovery test. Water-level measurements were continued for about 48 hours more. The test was terminated at 1:30 p. m. on March 21, at which time the control of the pumping schedule was returned to the waterworks operator. Changes in barometric pressure were recorded during the entire test period.

ANALYSIS OF TEST DATA

ADJUSTMENTS

Before evaluating the results of the test, the measured draw downs (table 7) were adjusted as necessary to eliminate the effects of extraneous factors that caused water-level changes.

FIGURE 12. Semilogarithmic plot of drawdown data and recovery adjustment, observation well 11.

To compensate for the slight water-level recovery that was in progress during the test, an adjustment curve similar to curve B in figure 12 was prepared for each well. Curve A in figure 12 was plotted from observed data and represents the recovery of the water level in well 11 resulting from the stopping of pumping well

GROUND WATER 57

8 The adjustment increment As (the distance between the water level at the time well 8 was started and the extension of curve A) was replotted as curve B in terms of the time since the pumping of well 8 started. The adjustment increment As was added to the observed drawdowns, and the adjusted drawdown (s + As), plotted as curve C in figure 12, was plotted beside the observed drawdown (s), as shown in figure 13. A comparison of the ob served data with the adjusted data showed that only the measure ments of the water level in well 11 were appreciably affected; hence, only the data from well 11 were adjusted for the final computations.

GROUND WATER 63

No other adjustments were deemed necessary. The personal and mechanical functions involved in the making of the test were so well controlled that corrections for these were unnecessary. Recorded barometric fluctuations were compared with observed water levels; however, as the barometric effects were small and tended to balance out during the test period, no barometric adjustment was made.

TRANSMISSIBILITY AND STORAGE COEFFICIENTS

The transmissibility and storage coefficients were computed by means of the Theis nonequilibrium method, which was described by Wenzel (1942). The computations and values for coefficients of transmissibility and storage are shown on figures 13 to 19. The drawdown test gave consistent values for transmissibility, 10,000 gpd per ft, and the values for storage coefficient ranged between 0.00012 and 0.00021. Because the thickness of the water-bearing sands in the well field is not uniform, an accurate determination of the permeability is impossible. The average of the reported thick nesses of the water-bearing sands penetrated by eight of the wells is about 55 feet; hence, the indicated permeability is 10,000-^- 55, or about 180 gpd per ft2. The logs of these wells indicate that the water-bearing sands may not be directly interconnected. The lower transmissibility value obtained from the recovery test on well 4 probably indicates that this well does not penetrate all the

sands penetrated by well 8. A plot of the recovery data for well 4 did not produce a curve that could be used for computing transmissibility. It did, however, indicate that any portion of the curve that might be selected for computation would produce a transmissibility much smaller than that computed from data for other wells.

HYDRAULIC BOUNDARIES

If all the plotted drawdown data fit the Theis type curve for radial flow, the existing hydraulic conditions are assumed to be those of an infinite aquifer. However, if the later drawdown data plot above the type curve that is, the observed drawdowns are greater than indicated by the type curve the existence of one or more impermeable hydraulic boundaries is suggested; or, if they plot below the type curve that is, the observed drawdowns are less than indicated by the type curve a source of recharge is sug gested. The hypothetical impermeable boundary shown by the plotted curves in figures 13 to 19 was studied by examining the shape of the departure curves. (See fig. 20.) In the image-well

method of analysis for a single boundary, described by Ferris (1948), the departure curve is considered to indicate the presence of an image well that started pumping at the same time and at the same rate as the real well. This condition is satisfied if the depar ture curve the coordinate used for each departure point assumes

its abscissa from the curve below fits the type curve and if sd = s at the common match points. Because time (t) for the image well is the same as for the real well, the relationship of the distance of the observation well to the image well (rO and of the observation well to the real well (r) may be determined as follows :

The computations of the image distances are shown on figures 13, 14, 16, 17, 18, 19, and 20.

A circle whose radius is equal to the computed distance to the image well was circumscribed about each observation well. (See fig. 10.) Theoretically, if all the circles representing the computed distances to a single image well had intersected at a common point the position of the image well the hydrologic boundary would be a vertical plane perpendicular to and bisecting the line connect ing the image well with the pumped well. As there was no such common point of intersection, either the boundary is not a vertical plane or none exists. Because the water-bearing beds penetrated by all the wells used in the test are known to be hydraulically con nected, a vertical boundary could not possibly exist between any two wells in the well field; hence, only those intersections outside the well field could indicate the position of an image well. There fore, a boundary, if it exists, is a short distance northwest of the well field. No attempt was made to locate a boundary more pre cisely, because available geologic evidence fails to indicate the existence of a true boundary and some of the test data gave incon sistent results. Although the drawdown data from wells 6, 7, 9, 10, and 11 indicated the presence of a single true boundary, the drawdown data from well 5 indicated no such boundary even though the length of the drawdown test was ample for the same boundary effect to be noticeable at that well. Data from well 5 during the recovery test, however, did indicate a boundary image at a distance of 2,700 feet, and gave a transmissibility value of


6,900 gpd per ft, which is somewhat less than that obtained from wells 6, 7, 9,10, and 11. The data from well 4 during the recovery test were erratic and, because they did not conform with those from the other wells, could not be analyzed by similar methods. The data from well 4 indicated a transmissibility of less than 3,000 gpd per ft. The water-level data collected at well 6 during the test period showed much less effect from the recovery of well 4 than would be expected in view of the effects at well 5. The water levels in the other observation wells west of well 5 showed no response during the 48-hour recovery period, despite the fact that other evidence indicated the water-bearing beds penetrated by all wells are hydraulically connected. All available evidence being consid ered, the following conclusions have been reached: No single true plane boundary exists; the boundary effect indicated by the test data was caused by the lenticular nature of the water-bearing de posits ; and the hydraulic connection of water-bearing beds in the Riverton well field is imperfect across a north-south line passing between wells 5 and 6.

ESTIMATE OF WELL-FIELD PERFORMANCE

The test results provide a basis for understanding present well problems and for predicting the future performance of the well field. Inspection of the test data indicates a large lowering of the water level in wells close to the pumped well. Obviously, the pumping of two closely spaced wells at the same time results in a considerable loss of efficiency. An example of the interference that may be expected if wells are spaced at various intervals as suming idealized boundary conditions, is shown in figure 21. If the pumping lift of a well cannot be increased, the yield of the well will decrease. To obtain maximum efficiency from the Riverton well field, it would be necessary to decentralize pumping as much as possible and to space new wells as far apart as practical.

In making a prediction of well-field performance, it is neces sary to consider the effects of the previously described boundary condition. Although the existence of a true boundary was not established by the results of the aquifer test, the approximate location of the boundary described above was used in the prediction of the general performance of the Riverton well field. To compute the effects of pumping at great distances from the well field, the total discharge from the field is assumed to be from a centrally lo cated point within the well field. The drawdown effects with respect to the distance from the approximate center of the well field, if no source of recharge is intercepted, are shown in figure 22. Because of the uncertainties of the test results, figures 21 and 22

should serve only as a rough guide in predicting future well-field performance.

By observing water levels in wells remote from the well field the relation of recharge to discharge can be determined. (See fig. 9.) Depletion of the aquifer, which is indicated by a decline of water level in the distant observation wells, contines until the drawdown cone intercepts enough recharge to equal the discharge. So long as the water level in the distant observation wells remains constant, recharge is in equilibrium with discharge. An increase in the average yearly pumpage will be reflected by a renewed decline of the piezometric surface. If water-level measurements and amounts of pumpage are accurately recorded, the continuous evalu ation of the ground-water reservoir and the prediction of the ef fects of any proposed development will be a relatively simple matter.

RELATION TO PROJECT AREA

Because it is likely that the sandstone beds penetrated by the city wells are similar to those elsewhere in the project area, the permeability of the water-bearing material in the Riverton well field should be of the same order of magnitude as that in other parts of the area. Therefore, in places on the project where a known thickness of sandstone of the Wind River formation is penetrated and artesian conditions prevail, it is possible to make estimates of

A more reliable estimate can be obtained by making an aquifer test at the site in question, and this procedure is recommended where relatively large supplies of water are required.

CHEMICAL QUALITY OF THE GROUND WATER

By W. H. DURUM

The chemical quality of ground water is related to the lithologic character of the rock materials through which the water moves, to the rate of movement, and to the length of time the water is in contact with such materials. Changes in the chemical composition of the ground water in the Riverton irrigation project result from recharge owing to irrigation, return flow, and influent seepage from canals; geochemical interpretations of such changes are made insofar as possible. For the purpose of discussion, the area from which ground-water samples were obtained for chemical analysis

QUALITY OF GROUND WATER

Dissolved solids in ground water result from the solvent action of percolating water on minerals in the soil and rocks. The water dissolves soluble salts and organic compounds in the soil and, assisted by the chemical action of other dissolved constituents, particularly carbon dioxide, decomposes rocks and minerals. Ce menting materials, such as carbonates and silicates, are particu larly susceptible to chemical decompostion. Changes in the chemical composition of the dissolved constituents of the ground water indicate to some extent the types of water-soluble minerals in the strata through which the water percolates. The range in concentration of several constituents in the samples of water from wells in irrigated tracts is given in table 8.

Sulf ate is the predominant anion in most samples of deep ground water in the Riverton project area. The exact nature of the chem ical alteration from a bicarbonate type of recharge water to a sodium sulfate type of ground water is not known. The results of analyses of some samples indicate that the explanation is simply that of accretion of soluble sulfates, followed by cation exchange. Undoubtedly, the accretion is an important factor in this area, as sulfate-bearing minerals are commonly present in the surficial de posits. Epsomite (MgSO4 -7H2O), probably deposited by ground water, is present in terrace deposits north of Muddy Creek, and water from one of the flowing wells near Muddy Creek has a rela tively high content of calcium and magnesium sulfate. However, the chemical characteristics of water from some sources, especially water that has a deficiency in bicarbonate ion, indicate a rather complex series of chemical reactions in the formation of the water type.

In areas where the depth to confined water is greater, the phe nomenon of cation exchange generally occurs as the water infil trates the soil and bedrock. When the water is in contact with sodium-bearing materials, the calcium and magnesium ions are replaced by sodium and the water is made correspondingly softer. The degree of the chemical replacement is indicated by analyses of samples from deep wells (Al-4-27dd, 34ad, and 34bb2) that sup ply the city of Riverton. The percent sodium exceeds 90, and the hardness is as low as 5 ppm. (See table 9.)

low stream terraces, or the deeper sandstones of the Wind River formation within the Riverton-Le Clair district. (See table 9.) In general, the ground water from these sources is of moder ately low mineral content; dissolved solids ranged from 247 to 830 ppm in the samples that were analyzed. The total hardness ranged from 5 to 270 ppm, and the noncarbonate (permanent) hardness ranged from 0 to 107. In most samples sodium was the predominant anion, and in several the amounts of iron were sig nificantly large. Water-bearing materials less than 100 feet deep, recharged by the dilute Wind River water, may yield water that is similar in mineral content to, although harder than, water in aqui fers several hundred feet deep. For example, water from well Al-2-3da, drilled to a depth of 41 feet, had 256 ppm of dissolved solids and a hardness of 165 ppm. Also, the chemical character of this water closely resembles that of the sample from the Wind River above the Le Clair diversion dam. However, the ground water is somewhat more mineralized, particularly in bicarbonate, than the weighted average of daily samples from the Wind River at Riverton for the 1948 water year. The composition of the water from these sources is shown in table 10.

The chemical character of water from deep wells in the Riverton- Le Clair irrigation district is similar to that of water from deep wells in the Midvale irrigation district. Many of these wells yield moderately mineralized water that is characterized by a high per cent sodium and is generally soft.

A plot of the data obtained for wells in the Riverton-Le Glair irrigation district shows that the hardness of the water is consist ently less than about 200 ppm at depths greater than about 100 feet. Coincident with this relatively low hardness is greater uni formity of high percent sodium with depth. (See fig. 25.)

MIDVALE IRRIGATION DISTRICT

Several fairly well defined relationships are apparent from the results of analyses of 51 samples from wells in the Mid vale irriga tion district. (See table 9.) In general, wells less than 200 feet deep yield highly mineralized sulf ate water, the result of leaching by infiltrating irrigation water. The water is characteristically hard unless the well draws from an aquifer in which the water is diluted by canal seepage of better quality, and the iron concentra tion in the water in many wells is higher than is desired for most uses.

In the Midvale district the concentration of dissolved solids tends to decrease with depth of well. (See fig. 25.) The plotted points depict a similarity in mineral content for the water in wells that have a depth greater than 300 feet. This similarity indicates that the chemical quality of water below this depth in the Wind River formation probably is unaffected by surface recharge and, in general, may be expected to be more dilute than the water from shallow sources.

The relation of anions to dissolved solids in samples of ground

and sulfates are proportionate to each other, but carbonate and chloride are of minor significance in water in which the content of dissolved solids exceeds 1,000 ppm.

Although the percent sodium in samples of water from depths less than 125 feet ranges widely, the percent sodium generally in creases with depth. Coincident with the increase is the reduction in hardness; water from most deep wells is softer than water from shallow wells. (See fig. 25.) The high concentration of alkaline earths in samples that were obtained from shallow wells in the Midvale irrigation district contrasts sharply with the characteris tically low hardness of samples that were obtained from wells on the low terraces and bottom lands along the Wind River. This is not surprising because of the more complete leaching of the surficial materials on the older irrigated tracts in the Riverton-Le Clair irrigation district.

The analysis of water from well A2-2-15dc, 22 feet deep, indi cates dilution of the shallow ground water by seepage from Pilot canal. The dissolved solids concentration of the water is 618 ppm,


the hardness is 116 ppm, and the chemical quality is satisfactory for general domestic use.

Well A3-2-26ad, 321 feet deep, is near the north edge of Ocean Lake. The water from this well contains 1,530 ppm dissolved solids, of which 988 ppm is sulf ate, and is more highly mineralized than water from most other wells that are deeper than 300 feet. Although the well reportedly is cased to a depth of 296 feet, there is a possibility that the casing is leaking and that more highly mineralized water from shallow horizons is entering the well.

OTHER TRACTS

In areas other than the Midvale and the Riverton-Le Glair irri gation districts, only a few wells were available for sampling. Five samples were obtained from the North Pavillion area, two samples from the North Portal area, and five samples from the Muddy Creek terraces. (See fig. 23 and table 9.) Most of these samples were obtained after the main Wyoming canal had been ex tended and therefore represent comparatively new supplies.

In the North Pavillion area a field permeability test was made by pumping temporary well A3-2-6ac, 41 feet deep. As shown in the following abridged analysis (table 11), the total mineralization particularly the hardness (calcium and magnesium) and sulfate increased significantly from the sample collected 36 minutes after pumping began to the sample collected 23 hours and 50 min utes after pumping began; sodium increased to a somewhat lesser extent than hardness and sulfate. The data indicate possible in duced infiltration of water from an aquifier that contains water having greater concentration of calcium sulfate. The data indicate possible induced infiltration of water from an aquifer that contains water having greater concentration of calcium sulfate.

The water from well A3-3-6cc, 270 feet deep, had a moderately low mineral content (272 ppm) but was reported unsatisfactory for drinking because of the strong hydrogen sulfide odor and the precipitation of sulfur on standing. Although no gas analyses

GROUND WATER 83

were made, the problem of hydrogen sulfide in water supplies, par ticularly in deep wells, was observed for new supplies in other tracts. Some preliminary investigations by the writer have indi cated that a commercial unit of exchange resins is a possible means for the removal of hydrogen sulfide from water of otherwise good quality; however, aeration of the water probably will be a satis factory method if the supply can be protected from freezing. The water from well A3-3-6cc had almost no hardness, presumably as a result of base-exchange reactions.

In the North Portal area, samples from wells A4-3-13dcl, 465 feet deep, and A4-3-34ad, 305 feet deep, were similar in total min eralization and in chemical composition. The hardness in the water was very low; and although the water was somewhat higher in sulf ate and fluoride than is desirable, it was of acceptable quality for domestic use. It is of interest to note that the concentration and composition of the water from well A4-3-34ad were similar to those of the water from several wells of comparable depth in the Midvale irrigation district.

The analyses of five samples from shallow and deep wells in the Muddy Creek terraces are indexes of the quantities and composi tion of mineral substances that can be expected in supplies from this area. Deep wells, such as A4-4-20da and A4-4-23dbl, yield water having the softness and the high percent sodium that char acterize water from deep wells in other parts of the project area. (See table 9.) The rapidity of the alteration from a calcium bi carbonate irrigation water to a sodium sulfate ground water sev eral times more concentrated is indicated in the results of analyses of samples from observation wells A4-4-23ac and A4-4-23db2. The analyses of water from these wells, which are on the experi mental farm, further indicate that a water supply obtained at shallow depth from terrace deposits in a newly irrigated area is likely to be appreciably mineralized during the early life of the well. However, the general degree of mineralization is somewhat less than that of water at shallow depths in the bedrock.

SEASONAL FLUCTUATIONS

It was recognized early in the study that irrigation water prob ably influenced significantly the quality of ground water in per meable materials adjacent to the canals. So that these seasonal changes could be observed, the water in three shallow wells (A3- 2-7dd, A3-2-14aa2, and A3-2-27ba) was sampled periodically; well A3-2-27ba was selected because the immediate area was waterlogged. The analytical results for selected constituents are given in table 12.

FIGURE 27. Seasonal fluctuations of dissolved solids and sulfate in water from selected wells.

GROUND WATER 85

The more significant changes occurred in the water in wells A3-2-7dd and A3-2-14aa2 as a direct result of dilution by irriga tion water from the main Wyoming canal or its laterals. The changes in dissolved solids and sulfate are shown graphically in figure 27. Largely through reduction in the content of calcium and magnesium sulfate, the dissolved solids in water from well A3-2-14aa2, 40 feet deep, decreased from 698 ppm in the post- irrigation season of 1948 to 284 ppm in the peak-irrigation season of 1949, then increased to 635 ppm prior to the 1950 irrigation season. The seasonal fluctuations are less pronounced for the samples collected in 1950 and 1951 and show a slight downward trend in concentration. By comparison, much greater fluctuations occur in the mineral content of samples collected in 1950 and 1951 from well A3-2-7dd, 36 feet deep. The residents of the area detect the increase in hardness of their supplies during the winter season.

Changes in the dissolved solids and sulfate in samples from well A3-2-27ba are not as pronounced. Evidently no dilution effect is apparent during the irrigation season because the ground-water level is already high in this immediate area. (See fig. 27.) It is obvious from these results that a long period of flushing action by surface water will be required to improve permanently the quality of the shallow ground water in waterlogged areas even if water levels are lowered. Periodic sampling and water-level measure ments of key wells should be continued as a part of the hydrologic studies in the area.

QUALITY OF WATER IN RELATION TO DRAINAGE

A total of 17 samples was collected from 13 surf ace-water sources in connection with this study. (See fig. 23 and table 9.)

The total concentration of dissolved solids in the Wind River at the Wind River diversion dam was only 262 ppm and is an index of the high quality of the irrigation supply. Occasional checks of the water have indicated that the total mineralization of the canal water remains essentially unchanged in its course through the area.

The chemical character of the water in Fivemile Creek and drains, however, changes significantly in a downstream direction. (See table 9.) A sample of water from upper Fivemile Creek (SW^ sec. 24, T. 4 N., R. 1 E.), which was collected at a time when the main Wyoming canal water was closed off, had a rela tively low mineral content of 451 ppm of dissolved solids. Return flows from irrigation enter Fivemile Creek downstream from this point and effect an increase in the dissolved-solids content to 2,730 ppm near the confluence with the Wind River. This sixfold in crease in dissolved solids is evidence of the large amount of soluble


salts being leached out of the upper part of the Wind River forma tion and the mantling deposits. A sample of water from lower Fivemile Creek, obtained about 1 year later, contained 1,660 ppm of dissolved solids. This difference of more than 1,000 ppm was caused principally by surface-water dilution.

The similarity in the chemical character of the water in Ocean Lake in 1947 and in upper Ocean drain in 1947, 1948, and 1949 is shown by the dissolved-solids concentrations of 2,290, 2,240, 2,120, and 2,160 ppm, respectively. Except for an increase in the per cent sodium from 67 to 72 and a decrease in calcium bicarbonate and in pH, the quantities of the various constituents have remained about the same. Apparently the process of leaching of the soil and surficial materials in the area is progressing at a fairly uni form rate.

MINERAL SUBSTANCES IN THE ROCKS AND SOILS

Salt deposits have formed in some parts of the Riverton irriga tion project area, especially west of Ocean Lake. These materials probably are dissolved principally from the shale and are precipi tated at the ground surface by evaporation of the ground water that moves to the land surface by capillary action. Although the salts are dissolved by light rain, they reappear at the land surface after a few days of dry weather. Samples of salt crusts were ob tained from three areas, and the results of analyses, expressed as percentage composition of the salts, are given in table 13.

As might be expected, the chemical character of the ground water in the area is related to these salt deposits; however, the proportion of the constituents usually differs. Sodium sulfate is the predominant salt. In terms of chemical equivalents, the cal cium sulfate content of salt at Pilot Butte Reservoir is approxi mately 34 percent, which is a proportion similar to that in the ground water in the vicinity.

Several samples of water-bearing material of sandstone or shale origin, representing different ground-water conditions in the area, were obtained by use of a soil auger and were analyzed for the

water-soluble constituents. (See table 14.) The two samples from sandstone-derived soils in nonirrigated tracts in the NE*4 SWi/i sec. 16, T. 3 N., R. 2 E., were slightly less mineralized than samples from other sources in the area. The water-soluble substances, composed principally of calcium carbonate, totaled less than 0.10 percent of the dry weight of the soil. On the other hand, the total soluble salt content of a sample of shale-derived soil in an untilled area was 0.14 percent. It also was composed principally of calcium carbonate.

Samples of well-drained soil from irrigated tracts in the NEl/4 SEi/4 sec. 7, T. 3 N., R. 2 E., contained higher concentrations of soluble salts than samples of untilled soil, but the carbonates of calcium plus magnesium also were prominent in these samples. In both samples from waterlogged areas in Paradise Valley (SEi/4 SE14 sec. 18, T. 2 N., R. 4 E.) and near Pavillion (SE^SWi/4 sec. 2, T. 3 N., R 2 E.), the total salt content exceeded 0.5 percent, and the percentages of sodium plus potassium and of sulfate were more prominent.

Kearney and Scofield (1936) and other investigators have estab lished arbitrary limits for separating saline and nonsaline soils. They consider that plants are affected when the salt content of the soil exceeds 0.1 percent. It is apparent from the results given in table 14 that harmful concentrations of salts are being deposited in soils in poorly drained areas.

Chemical analyses of acid-soluble constituents in both unweath- ered and weathered shales were made in order to determine further those mineral substances possibly affecting the character of water that percolates from the ground surface. (See table 14.) The shales are composed principally of iron and aluminum silicate and contain appreciable quantities of calcium, magnesium, sodium, and potassium. Considerable effervescence resulted from the addition of the hydrochloric acid; apparently an appreciable quantity of carbonates is present. The sulfate content of both samples is low. These results do not provide the evidence necessary to demonstrate the source of sulfate in the water; moreover, because only a few samples were collected, the results given in table 14 may not neces sarily be representative of surface or subsurface conditions.

Typical chemical analyses of soil profiles in the Midvale irriga tion district have been extracted from the large volume of data made available by the United States Bureau of Reclamation at Riverton to illustrate the various soil conditions in one segment of the project. The terms used in describing soil conditions and soil classes in table 15 are defined by the United States Regional Salin ity Laboratory (1947). Although most of the soils examined were

of the normal arid type, four classes of soils normal, nonsaline alkaline, saline alkaline, and saline types are represented in the data collected. All analyses in table 15 were by U. S. Bureau of Reclamation.

In places the soil type differs appreciably within a profile. For example, a normal soil at the surface is immediately underlain in some places by nonsaline alkaline soil; conversely, nonsaline alka line soil at the surface may be underlain by normal soil. Although either sodium or calcium may be the predominant cation in normal soils, percent sodium that exceeds 60 is common in the four soil types. Differences in the bicarbonate and total cations indicate predominance of strong acid radicals, presumably sulfate.

QUALITY OF WATER IN RELATION TO USEDOMESTIC USE

The United States Public Health Service (1946) recommends the following maximum concentrations of chemical constituents in water to be used for drinking purposes on common carriers:

Maximum Maximumconcentration concentration

Constituent (ppm) ConstituentIron and manganese together.. 0. 8Magnesium ................. 125Sulfate ..................... 250

Fluoride .................... *!.5Chloride .................... 250Dissolved solids ............. 2500

1 Mandatory upper limit.2 Where water of this quality is not available, 1,000 ppm is permitted.

These standards, together with other sanitary, chemical, and bio logical requirements, are applicable primarily to interstate com merce but can be used also in evaluating the suitability of a water for private and public supplies. Many supplies in the area are of higher mineral content than desirable; sulfate and iron are the principal constituents that exceed the standards.

Many domestic wells in the Midvale irrigation district and in the newly opened tracts, particularly those drawing water from shallow sources, yield water in which the hardness exceeds 200 ppm. Such supplies, in addition to their scale-forming character istics, are of economic significance to the consumer because of added soap costs. Fluoride, which reduces tooth decay if present in quantities of about 1.0 ppm but which may promote dental mot tling if present in quantities of more than about 1.5 ppm (Dean, 1936), is higher than desirable in some of the supplies from both shallow and deep sources throughout the area. In the Muddy Creek terrace area the leaching effect of irrigation water probably will maintain, temporarily at least, a somewhat high concentration of fluoride in shallow sources of water. Many ground-water sup-

GROUND WATER 91

plies in the report area are high in iron. Although several parts per million of iron may be in solution as iron bicarbonate in the ground water, oxidation of the iron to ferric hydroxide and subse quent precipitation occur when the water is exposed to air.

Water containing minerals in excess of the recommended stand ards often is used for drinking as well as other purposes. Many consumers in the Riverton area have become accustomed to the saline properties of the water and now find less mineralized water somewhat less palatable. However, the water from several of the wells that were sampled, particularly the water having excessive concentrations of dissolved solids, is used only for the watering of stock and fowl.

IRRIGATION USE

A small but definite amount of boron in either the soil or the irri gation water is essential for satisfactory crop growth, but for certain crops a toxic effect results from too great an amount of boron in the irrigation water. Water containing more than 2.0 ppm of boron should not be used for the irrigation of crops sensi tive to this element. None of the samples of water that were analyzed had troublesome quantities of boron; the maximum was 0.98 ppm.

Wilcox (1948, p. 27) and others have given criteria for classify ing irrigation water and have indicated that if the specific con ductance is less than 1,000 micromhos, salt probably will not accumulate in the soil, but if the specific conductance is more than 3,000 micromhos, salt is likely to accumulate. Percent sodium also is an index of the suitability of a water for irrigation because a high proportion of sodium in the water generally adversely affects the physical properties of the soil. For most soils the percent sodium of the irrigation water should be less than 60; although for soils having a good structure and permeability, a percent sodium as high as 75 may not cause adverse effects.

Water in the Riverton irrigation project may be rated for sup plementary irrigation use on the basis of a diagram devised by Wilcox (1948, p. 26). (See fig. 28.) This diagram is based on the percent sodium and the specific conductance of the water. (See table 9.) The section of the diagram into which a plotted point falls signifies the quality classification of the water.

The analyses of only three samples, all from wells in tracts that have been irrigated for a number of years, rate excellent or good; most of the supplies rate no better than doubtful. The data con sidered together with analytical results obtained for soils indicate

a generally unsatisfactory supply of ground water for irrigation. Reuse of return irrigation water also should be avoided.

Wilcox points out that the soil, crop, climate, drainage, and management of the soil influence the tolerable quantities of salts in irrigation water; thus, no simple classification is applicable to all conditions.

In the Riverton irrigation project area, ground-water supplies are derived principally from the sandstone beds of the Wind River

Although generally not available in quantities large enough for irrigation, the water yielded by the formation is adequate in quantity and of suitable quality for mu nicipal, domestic, and stock use. Additional sources of satisfactory water from this formation possibly can be obtained at greater depths than now penetrated.

Except where the terrace deposits and the valley alluvium have been recharged for a number of years by seepage from canals and irrigation water or by streamflow, with consequent leaching of salts, most surficial deposits in the report area yield water neither sufficient in quantity nor suitable in quality for domestic or stock use. The continuation and expansion of irrigation will result in the development of ground-water bodies in the terrace deposits along the tributary streams. The quality of the water throughout these aquifers will improve in time if drainage is sufficient to allow the flushing of deleterious salts from them. Wells drilled where the aquifer is recharged by dilute surface water are likely to ob tain water of suitable quality. In most places the colluvial-alluvial and alluvial deposits are not potential aquifers because they have low permeability and the water in them is likely to be of poor quality.

Available evidence indicates that, before irrigation, ground water in the surficial materials either was nonexistent or generally was far below the surface and that infiltration from canals and applied irrigation water either has formed a permanent ground- water body or has enlarged one already present. Where the per meability of the surficial materials was great enough to allow the water to move through and be discharged from them, the added re charge caused no great rise of the water table, but where the natural underdrainage was poor, the recharge exceeded the dis charge and the water table rose progressively closer to the surface. As shallow ground water generally is highly mineralized, evapora tion of the water at or near the surface leaves a concentration of salts that further hinders the drainage of the materials and the use of the land for agriculture. Because most of the surficial materials mantling the report area are poorly drained and because the underlying bedrock is relatively impermeable, serious water logging and the accompanying salinization of the soil have oc curred or will occur in many places both in the Riverton irrigation project and in adjacent privately irrigated land. Properly de signed and strategically located drains would lower the water table in some of the waterlogged areas and, unless the soil has been permanently damaged by the salts, the land again can be cultivated.


However, adequate drainage systems or other measures of im provement can be designed only after the hydrology and geology of the problem areas have been studied in detail. The present general study indicates not only wherein the origin, geologic na ture, and physiographic expression of both the surficial materials and the underlying bedrock contribute to these problems but also the factors that should be considered in resolving them.

The area covered by this investigation is subdivisible into sev eral distinct geomorphic units, in each of which the drainage prob lems are somewhat different.

The lower Wind River terraces, which have been irrigated for several years, are waterlogged in many places along or near the base of slopes between terraces and in some places within the ter races. Waterlogging at the upper margin of a terrace generally is caused by discharge from a higher terrace of ground water or irrigation return flow in quantities too large to be transmitted by the lower terrace. A drain that exposes the full thickness of gravel along the outer terrace edge would intercept the discharge of ground water from that terrace onto the next lower terrace. Terrace T2, which is waterlogged in the vicinity of Riverton, is likely to become waterlogged in the Hidden Valley area also, be cause that area is underlain by rather thick and relatively imper meable deposits. As discharge at the terrace edge is retarded and the movement of water within the upper part of the terrace deposits is slow, interception drains penetrating the full thickness of gravel would help alleviate this situation. However, a detailed study should be made to determine the permeability and thickness of the terrace gravel and overlying alluvium and to detect the possible presence of water under hydrostatic pressure in either the terrace deposits or the underlying- Wind River formation. If the ground water is confined, the construction of relief wells might be a means of alleviating waterlogging.

The Muddy Creek terraces, which are irrigated to some extent at the present time, possibly will become waterlogged by perched ground water if the sodium-dispersed soil of some of the terraces retards the downward movement of irrigation water into the underlying terrace gravel. After irrigation has been continued for several years, a high water table may cause waterlogging along and near the base of slopes between terraces unless intercepting drains prevent the movement of ground water out of higher terrace deposits into lower terrace deposits. Waterlogging may occur also in the colluvial-alluvial materials, which in places completely mantle the slope between terraces. If these materials retard the flow of ground water from higher to lower terrace deposits, pro-

SUMMARY AND CONCLUSIONS 95

gressive waterlogging will occur near the contact of the colluvial- alluvial material with the higher terrace. Interception drains ex posing the full thickness of terrace gravel along the terrace edge would increase the discharge of water from the terrace deposits. At least one line of observation wells along a cross-valley profile should transect each of the eastern, central, and western parts of the terrace system. Measurements of the water level in the wells in irrigated areas will indicate at an early date if the trend is toward high water-table conditions. The possibility of the develop ment of perched bodies of ground water also should be taken into consideration.

The three cross-terrace channels, the eastern one of which con tains a series of blowouts now interconnected by Cottonwood drain, will serve as natural ground- and surface-water drains. Measures to prevent gullying may be necessary while the drains adjust to the new conditions of flow.

Problems of erosion along Muddy Creek, similar to those along Fivemile Creek, can be prevented if the discharge of ground water and irrigation return flow from the Muddy Creek terrace system is diverted into drains instead of directly into the creek. If a drain that exposes the entire thickness of gravel along the outer margin of terrace T3 were constructed parallel to Muddy Creek, it and Cottonwood drain would intercept all the excess surface-water dis charge and most of the ground-water discharge resulting from the irrigation of the terraces. Properly designed drop structures would be an essential feature of the new drain. Both drains could discharge into the large closed depression at the lower end of Cottonwood drain and the release of the water from the depression into Muddy Creek could be controlled.

Drainage problems in the terrace systems along Fivemile and Cottonwood Creeks are unlikely because the individual terraces, although similar in many respects to those along Muddy Creek, are small in area and are isolated.

In a large part of the investigated area the Wind River forma tion is either at the surface or is mantled by only colluvial-alluvial deposits. Wherever the colluvial-alluvial deposits are thin or dis continuous, wherever local irregularities or abrupt changes in the slope of the underlying bedrock surface impede or reduce the lateral movement of water, and wherever the permeability of these deposits and the underlying bedrock is so low that discharge from the deposits is less than recharge to them, drainage problems either have developed already or are likely to develop. After colluvial-alluvial deposits have become waterlogged, it is question able whether they can be drained effectively. Where waterlogging


has not yet occurred, rigid control of water use and reduction of canal losses may forestall waterlogging. In newly irrigated areas, such as the North Portal area, three cross-valley lines of observa tion wells that penetrate the full thickness of the colluvial-alluvial material should be constructed, and periodic measurements of the water level in the wells should be made in order to foretell any trend toward high water-table conditions. Also, lands proposed for irrigation in the Muddy Ridge extension of the Riverton project should be evaluated according to their drainability. The design and construction of drainage facilities in any area should be pre ceded by detailed geologic and hydrologic studies.

Waterlogging of the alluvial bottom lands along the Wind River, especially in the eastern part of the area, has been caused primarily by the discharge of ground and surface water from the adjacent terrace. The construction of interception drains at the terrace edge probably would alleviate the condition in areas already water logged and prevent the extension of the affected areas. Along the middle and lower parts of Fivemile Creek the irrigation of the valley alluvium or adjacent colluvial-alluvial deposits has caused waterlogging of the alluvium. Because the alluvial deposits are relatively impermeable, these areas possibly could never be well drained. Reduction of the amount of irrigation water applied to the land and reduction of water loss in canals and laterals are probably the most effective means of controlling waterlogging in these areas.

The hydrologic properties of the Wind River formation in the Riverton area were determined by making an aquifer test in the Riverton municipal well field. The transmissibility and storage coefficients of the Wind River formation were computed to be about 10,000 gpd per ft and 2 x 10-4, respectively. The results of the test, which include a consideration of the effects of boundaries, aid the understanding of present problems in the Riverton well field and make it possible to predict approximately the future perform ance of the well field, including the expected drawdown interfer ence between wells under different pumping schedules and the distribution of the wells. Records of pumpage and of water-level fluctuations in wells also will be necessary for the most efficient operation of the well field.

Because the geologic and hydrologic conditions in the Wind River formation in the Riverton area are fairly typical of condi tions in the Wind River formation throughout the project area, a reasonable estimate of the yield of the formation can be computed for any part of the area for which the thickness of water-bearing sandstone is known.

SELECTED BIBLIOGRAPHY 97

In some parts of the Riverton irrigation project extensive water logging and the resultant deposition of salt on and in the surficial materials are altering the chemical composition and increasing the salinity of the shallow ground waer. The analyses of water from return flow to Ocean drain and Fivemile Creek indicate large amounts of soluble salts in the surficial deposits. The soluble-salt content in the soil in waterlogged areas probably exceeds 0.5 per cent in places, and continued saturation of the soil by water con taining a high percent sodium is likely to destroy the soil structure. Chemical analyses of soils made by the United States Bureau of Reclamation show that normal arid, saline, saline alkaline, and nonsaline alkaline soils are present in the Midvale irrigation district.

The concentration of dissolved solids in the ground water tends to be variable at shallow depth, but uniformly lower at greater depth. The available analyses indicate that the water from most of the wells that are 300 feet or more deep contains less than 1,000 ppm of dissolved solids. The sulfate content, however, probably exceeds the desired limits unless concentrations of dissolved solids are less than 500 ppm.

In all parts of the area the concentration of dissolved solids in the ground water increases in proportion to the increase in sulfate; the carbonate and chloride concentrations increase very little.

Because of variations in the freshening action of irrigation water from place to place, wells less than 100 feet deep yield water that has a wide range in percent sodium. At depths greater than 100 feet, the percent sodium generally is greater than 80; this fact indicates geochemical alteration and resultant reduction in hard ness. The high percent sodium generally will be a limiting factor in the use of ground water and drain water for irrigation.

Sulfate and iron exceed the accepted drinking-water standards in more than half of the ground-water samples collected in the area.

No analyses of the ground water in the area prior to irrigation are available for study. However, the degree of mineralization of the ground water to a depth of 300 feet in the newly irrigated tracts is sufficient evidence of the salinity problems that exist in the area.

WATER-LEVEL MEASUREMENTS

By measuring at intervals the depth to water in wells, a record of the changes in the amount of ground water in storage can be obtained. Such a record aids in determining the relative effect of the various factors of recharge and discharge to the ground-water reservoir. Measurements were made by the wetted-tape method in 4 wells in 1947, in 83 additional wells in 1948, and in several more wells beginning in 1949 and in 1950. Unless measurements had to be discontinued for some reason, they were made at monthly intervals until late in 1950 or early in 1951. A few wells were measured until the end of 1951. All measurements made by the tape method are given on pages 100 to 124 of table 16.

To obtain a continuous record of water-level fluctuations a water-stage recording gage was installed on 6 of the wells. Daily noon readings were taken from the recorder charts and are given on pages 125 to 130 of table 16.

LOGS OF WELLS

Logs of wells obtained from the Farmers Home Administration and from local well drillers as well as those of the United States Geological Survey are presented in table 17. Because it was im possible to verify the logs by examination of the drilling samples, the logs are presented without significant changes in the drillers' terminology. The logs are believed to be fairly accurate, although materials at depth designated "sand" probably are consolidated and should be called sandstone; it is thought that "hard rock" also is sandstone.

INVENTORY OF WELLS AND SPRINGS

The location of all known water wells in the area covered by this report is shown on plate 1. Pertinent available information on all wells shown on the map is given in table 18. Most drilled wells in the area penetrate sandstone beds of the Wind River formation. As it was impossible to obtain a measurement of the depth of every well or of the depth to water in all of the wells, the information given for some of the wells in the table is based on the memory of the owner or driller of the well.
