Girl Scout Camp Creek Trace Report

2014

Introduction

In 2013, a dye trace was conducted on Girl Scout Camp Creek in Yucatan Township, Minnesota

(Figure 1). Yucatan Township is located in western Houston County roughly 7 miles to the southwest

of the City of Houston. Dye traces have been completed in this general vicinity on other streams. Dye

tracing occurred on Daley Creek, located roughly 3.0 miles to the north of Girl Scout Camp Creek, in

2009. Dye tracing also occurred in 2012 and 2013 on Bridge Creek, located roughly 1.5 miles to the

north of Girl Scout Camp Creek. Reports of each of these traces are available as separate documents.

In addition, an ephemeral sinking stream has been identified on Hallum Creek, located roughly 1.5

miles to the southeast of Girl Scout Camp Creek, via GIS reconnaissance. Subsequent discussion with

the landowner verified the existence of the Hallum Creek stream sink.

Creek is located in close proximity to the Houston County/Fillmore County border. Streams identified as trout

streams are shown with dark blue lines.

All of these traces were conducted to further delineate springsheds in the area, characterize sinking

streams in the Cambrian St. Lawrence Formation, and characterize surface‐groundwater interactions

in the county. Characterizing sinking streams and their connection to cold water springs is important

as these springs are critical water sources for trout streams in southeastern Minnesota.

Dye tracing entails using fluorescent dyes to track groundwater flow directions and travel times. The

dye is poured into a sinking stream or sinkhole; from there it flows through a conduit system until it

re‐emerges at a spring. For the September 2013 Girl Scout Camp Creek trace, the red dye Rhodamine

WT was used. Table 1 identifies the input location and dye quantities used for the trace. Dye recovery

was accomplished using both direct water “grab” samples and passive dye detectors (packets of

coconut charcoal also known as “bugs”). All direct water samples and charcoal detectors were

returned to the University of Minnesota Geology & Geophysics Department Hydrochemistry

Laboratory for analysis. There, the charcoal detectors were opened, the charcoal was removed, and

the fluorescent materials were extracted using an eluent solution of 70% isopropyl alcohol, 30%

deionized water, and 10g/L NaOH. The eluent solution was then run through the Shimadzu RF5000U

scanning spectrofluorophotometer to detect and record the spectra. Direct water samples were also

analyzed using the Shimadzu RF5000U scanning spectrofluorophotometer. Spectral components,

including the background spectral components, were quantified using PeakFit software as described

in Alexander (2005).

The Girl Scout Camp Creek trace was designed and executed by Jeff Green & John Barry of the

Minnesota Department of Natural Resources (DNR). E. Calvin Alexander, Jr., of the University of

Minnesota Earth Sciences Department performed the sample analysis and interpretation.

2013 Trace: Background, Approach, and Results

The 2013 Girl Scout Camp Creek trace was run synchronously with a trace on nearby Bridge Creek

and was conducted to assist in the characterization of groundwatersheds that feed trout streams. The

trace was initiated on September 12, 2013 with the introduction of 1.057 kilograms of 20% weight

Rhodamine WT dye into a sinking pool (MN28:B00004) located in a tributary valley of Girl Scout

Camp Creek (Figure 2). John Barry and Jeff Green of the MNDNR and Calvin Alexander of the

University of Minnesota were present for the trace. Stream discharge at the time was estimated to be

0.25 cubic feet per second. Table 1 summarizes the dye input information.

Figure 2. 2013 Girl Scout Camp Creek site sampling locations and stream sink location.

Passive charcoal detectors (“bugs”) were in place at sampling locations from prior to the introduction

of the dye on September 12, 2013 until February 3, 2014 with the exception of the Strand nose spring

and Strand bank spring locations. These locations were not actively monitored until the majority of

the dye had left the hydrologic system.


2014

Rhodamine WT dye was detected at levels high enough for positive identification at multiple

sampling sites. Appendix 1 summarizes the 2013 trace dye analysis and highlights sites where dye

was detected using bold italicized cells. Rhodamine WT dye was detected in passive detectors at the

Whispering Hills Spring within 15 days of pouring dye and at the Peterson Spring within 14 days of

pouring dye. An early “breakthrough” time for the St. Lawrence nose spring was not recorded due to

mammals destroying passive detectors early in the trace. Dye had a strong presence at the St.

Lawrence nose spring during the first time frame, 27 September to 17 October, where the passive

detectors were not destroyed.

Assuming a straight line distance of 4357 feet from stream sink (28:B00004) to Whispering Hills

Spring, this translates to a minimum peak groundwater velocity of roughly 88 meters/day (290

ft/day). Assuming a straight line distance of 7047 feet from stream sink (28:B00004) to Peterson

Spring, this translates to a minimum peak groundwater velocity ranging of roughly 153 meters/day

(503 ft/day). These velocities are consistent with previous traces in the St. Lawrence where peak rates

range from 35 to 600 meters/day (Appendix 2).

Discussion

This dye trace proved that surface water that sinks in the upper reaches of a tributary to Girl Scout

Camp Creek resurges as groundwater at a minimum of three springs in the valley. Springs connected

to the sinking stream include the St. Lawrence nose spring (MN28:A00091), Whispering Hills Spring

(MN28:A00090), and Peterson Spring (MN28:A00028). Figure 4 graphically represents the

stratigraphy of the Girl Scout Camp Creek area and schematically represents potential dye trace

vectors in cross section view. The Girl Scout Camp Creek stream sink is located in the St. Lawrence

Formation; the Girl Scout Camp Creek nose spring (Nose Spring‐CSTL on Figure 3) emanates from

the base of the St. Lawrence while the other two springs discharge from the upper to mid Lone Rock

Formation of the Tunnel City Group. This trace confirms that surface water sinks and then moves

rapidly through the entire St. Lawrence Formation section and emerges at springs in the upper to mid

Lone Rock Formation.

Elevated levels of chloride and nitrate can be used as geochemical indicators of recent human

influences on groundwater. Elevated concentrations of these species can be attributed to the

application of road salts, the use of water softeners, and fertilizer application. Nitrate concentrations

greater than 1 part per million (ppm) are greater than background conditions and possibly indicate

that an aquifer has been impacted by activities on the land surface (Minn. Dept. of Health, 1998 and

Wilson, 2012). Nitrate concentrations greater than 3 ppm indicate that an aquifer has been impacted

by activities on the land surface (Minn. Dept. of Health, 1998). Chloride concentrations of greater than

5 ppm can also be used to indicate that an aquifer has been impacted by activities on the land surface.

Multiple investigators have used Cl/Br ratios to identify chloride sources to groundwater (Davis and

others, 1998; Panno and others, 2006). In general, samples with chloride to bromide ratios above 300

are waters that have been elevated by human activity.

Water samples collected in the Girl Scout Creek watershed on multiple occasions during the dye trace

and analyzed for anion chemistry show elevated nitrate and chloride levels in the upper watershed

surface water and spring waters and a dilution effect at springs located stratigraphically lower in the

section from a regional flow component. This observed pattern of high nitrate levels in surface water

and upper bedrock aquifers and nitrate poor water in lower units is a regional phenomenon recently

observed by Runkel (Runkel and others, 2014). Elevated nitrate levels in the Strand nose spring

suggest that water discharging from the spring is likely connected to the upper flow system.
