Lake Tippecanoe, James Lake and Oswego Lake Sediment Removal Plan

Executive Summary The Lake Tippecanoe, James Lake and Oswego Lake Sediment Removal Plan is the result of the efforts of the Lake

Tippecanoe Property Owners (LTPO) and concerned residents of the lakes. The LTPO has worked with the Indiana

Department of Natural Resources Lake and River Enhancement program for over the last 15 years to reduce sediment

and nutrient inflow into the lakes. As various projects have been undertaken within the watershed to control

sedimentation in to the lake, this group is concerned about identifying areas and calculating volume in order to apply

for funds to remove the existing sediment.

The LTPO are concerned about limited recreation capacity as well as diminished habitat and degraded water quality as

a result of sediment accumulation in specific areas within the lakes. The LTPO recognized the need to reduce the

amount of sediment coming into the lakes before undertaking the sediment removal process and has been working on

projects on lake inlets since the 1997 Lake Tippecanoe Diagnostic Study.

This Sediment Removal Plan addresses the amount of sediment located in areas of concern based upon LTPO input and

investigation, the chemical and physical composition of the identified sediment, and the removal process based on

IDNR guidance. The Plan identifies the areas where the removed sediment will be dewatered and the construction of

the sediment dewatering basin.

Private channels on the lakes were evaluated for sediment deposits, the results are included as part of the plan. As LTPO

moves forward to secure LARE funding for sediment removal on public areas of the lakes, the landowners of the

property around the private channels may find it to their advantage to consider concurrent sediment removal.

Potential cost savings to the channel owners include the dredge already being on the lakes and the possibility of using

the same sediment dewatering basin.

This Sediment Removal Plan, when paired with the corrective actions previously completed will improve water quality

and habitat and improve recreation possibilities in the lake.

Acknowledgements This Sediment Removal Plan was completed with funding from the Indiana Department of Natural Resources - Division

of Fish and Wildlife, Lake and River Enhancement Program, and the Lake Tippecanoe Property Owners, Incorporated.

Williams Creek Consulting, Inc., documented the historical information, completed the in lake sediment measurements,

collected samples for chemical evaluation, calculated the amount of sediment in the lake. A site meeting with Indiana

Department of Natural Resources was held to review sites and determine the permits needed for the sediment removal.

Special thanks are due to the lake residents of Lake Tippecanoe who volunteered their time, boats, and ideas.

Overall this document is about the influence of the inlets, recreational activity and associated prevailing winds effects

on Lake Tippecanoe, the efforts of the residents to remove the sediment, and restore the recreation and habitat benefits

by removal of accumulated sediment. This concerned group of residents is committed to protecting and improving

water quality and habitat within Lake Tippecanoe, James Lake (Little Tippy) and Oswego Lake and the surrounding

watershed.

Lake Tippecanoe, James Lake and Oswego Lake Sediment Removal Plan

1.0 Introduction This sediment removal plan has been prepared by Williams Creek to satisfy the requirements of the Indiana

Department of Natural Resources (IDNR) Lake and River Enhancement (LARE) Program for sediment removal projects.

The purpose of the plan is to provide a descriptive outline of the proposed sediment removal project, identify the

location, extent, and approximate volume of sediment to be removed, identify the proposed location for sediment

disposal, and provide a discussion of likely regulatory requirements.

The Lake Tippecanoe, James Lake and Oswego Lake Sediment Removal Plan was completed under the guidance of the

IDNR LARE Program Scope of Services and the Lake Tippecanoe Property Owners (LTPO) to address accumulated

sediment deposits and resulting algal growth within Lake Tippecanoe James Lake (Little Tippy), and Oswego Lake. The

accumulated sediment and resulting algae has reduced access to the Lakes for residents and other recreational users,

and has and will likely continue to spread if not controlled. The objective of this plan is to identify areas of the Lake

affected by sedimentation and algae, define the approximate amounts of material present, and outline a process for

removal and disposal.

For the purpose of this report the term Lake Tippecanoe encompasses Lake Tippecanoe, James Lake (Little Tippy), and

Oswego Lake.

2.0 Project Tasks The following sections define the proposed sediment removal project and describe the tasks necessary for its successful

completion.

2.1 Contact Information

The LTPO was formed in 1944 as the Lake Tippecanoe Protective Association for the purpose of preserving the health

and beauty of the Lake. The LTPO has continued to update and expand the goals of the original Protective Organization

and has developed a strategic plan to reach those goals. For the purposes of this Sediment Removal Plan and

associated LARE funding applications, the primary point of contact with the LTPO is Holly LaSalle.

2.2 Project Location

Lake Tippecanoe is an 880 acre lake (1,133 acres including James Lake and Oswego Lake) located in Kosciusko County,

Indiana. The watershed for the lake is 71,660 acres. Public access for the lake is located at the following locations,

Tippecanoe Boat Company (fee), Pie-Eyed Petey's Marina and Restaurant (fee), Patona Bay Resort (fee), Tippy Dance Hall

(fee), Grassy Creek Boat Launch (IDNR). The project site is located in the North Webster, Indiana USGS Topographic Map

Quadrangle, in Sections 8 and 17, Township 33N, Range 7E. The project site is located in the 8-digit hydrologic unit

code (HUC) 05120106, Tippecanoe watershed. Additionally the lake watershed is divided between two 12-digit

hydrologic unit codes (HUC) 051201060105 (Tippecanoe River) on the north and east; and 051201060104 (Grassy

Creek) south and east of the lake. Latitude: 41° 19’35.37” N, Longitude: 85°45’31.29” W. The site is located

approximately 2 miles due west of the town of North Webster, Indiana (Figure 1).

Figure 1: Location Map

Proposed dredge areas are distributed throughout the lakes. Eighteen areas identified for sediment removal include

eight private channel areas. Information for sediment removal for the private channels is being provided to the

individual channel associations so the groups may privately contract with the dredging company concurrently with

public areas being dredged.

2.3 Historical Information

The LTPO have a lengthy history of projects in and around the lakes. Table 1 represents the studies, reports and projects

completed on Lake Tippecanoe.

While these projects have significantly reduced the inflow of sediment from the watershed, other factors have

perpetuated the need for additional dredging to protect long term water quality, fishery habitat, and passive

recreational value.

2.4 Public Involvement

The LTPO is a voluntary organization with 722 members, representing approximately 60% of Lake Tippecanoe

homeowners. Actions of the LTPO represent the interests of the membership of the organization who have opportunity

to provide input and direction at organization meetings and through voting. Additionally, the LTPO is an active and

supporting affiliate of the Tippecanoe Watershed Foundation (TWF) which seeks to protect and preserve the quality of

water and aquatic resources throughout the entire watershed. All residents and users of the Tippecanoe watershed are

encouraged to participate in the initiatives of the TWF.

A Public Meeting was conducted on July 27, 2013 with 20 people in attendance to disclose information pertaining to

the proposed sediment removal and nutrient and sediment load reduction activities. During this meeting, attendees

were given the opportunity to comment on the planned activities, ask questions, and provide input on additional areas

to be measured. A second Public Meeting was held September 14, 2013 with 29 people in attendance. Measured

sediment amounts and locations were discussed. The potential for private channel dredging in conjunction with

dredging of public areas on the lakes was discussed.

3.0 Design Criteria Proposed dredge areas are distributed throughout the three (3) lakes. There are 18 locations identified for sediment

removal which include eight private channel locations (Figure 2). Information for the sediment removal of private

channels is being provided to the individual channel associations so that the groups may privately contract with the

dredging company concurrently with public areas being dredged.

3.1 Sediment Characteristics

Sediment dimensions were measured July 5, July 19, and August 1, 2013. During these dates, the depth to sediment

and depth to lake bottom were determined using a graduated measuring probe. Additionally, samples were collected

and sent to Sherry Laboratories for analysis to determine chemical composition.

3.1.1 Sediment Dimensions

Eighteen geographic regions of accumulated sediment were identified by the sampling exercises. The sampling sites

are shown in Figure 2.

Sediment depth sampling was conducted on a grid with samples collected at intervals of 25-50 feet. At each sampling

point, using a 3 inch PVC pipe marked in tenths, one reading was taken to determine the depth from the water surface

to the top of the sediment bed. Subsequently, a second reading was taken to determine the depth to the native lake

bottom. Sediment depth was determined for each sampling point by subtracting the first reading from the second.

These measurements were used to determine the average depth of the accumulated sediment and create a generalized

topographic map of the lake bottom. GPS coordinates were recorded at the sampling sites and imported into ArcGIS.

These coordinates were used to measure the surface area of the accumulated sediment. Table 2 summarizes the area,

average depth, and volume of the accumulated sediment.

Water depths recorded at the sampling points ranged from 1 to 5 feet and sediment depths ranged from 0.5 to 5 feet.

The area and average depth of the accumulated sediment were used to determine the volume of sediment to be

removed. The total approximate volume of the proposed dredged areas is 45,700 cubic yards.

3.1.2 Lake Bottom Mapping

The lake depth measurements recorded on July 5, July 19, and August 1, 2013 were used to create bathymetric maps of

the areas of the lake surveyed (Appendix A). The depths recorded for the top of sediment depict the current conditions,

while the depths of the lake bottom depict pre-sediment topography. Lake Tippecanoe has a dual lake level, the weir is

set at 836.40’ (mean sea level) and lowered to 835.90’ (mean sea level) from November 1 through April 1 every year.

The lake level at the time the sediment measurements were recorded was at or slightly above the 836.40’ level.

3.1.3 Particle Composition

Sediment samples were visually inspected at the time of collection. Sediment was found to consist of silt/organic

material and sand. Only a small amount of gravel was located at the Indian Creek inlet site. No large cobble was found

at any of the sites.

3.1.4 Chemical Composition

Sediment samples were collected on September 14, 2013. A map of the locations of the sediment samples is shown in

Figure 3. Samples were bagged and transported to Sherry Laboratories. Table 3 provides a summary of the lab analysis

and the Indiana Department of Environmental Management (IDEM) land application concentration limits. Lab results

are included in Appendix B.

3.2 Lake Tippecanoe Description

Lake Tippecanoe is a glacially created lake with hydrologic connectivity to the Barbee Lakes, James Lake, and Webster

Lake. Lake Tippecanoe is the deepest lake In Indiana with a maximum depth of 122 feet. Lake James and Oswego Lake

are somewhat shallower with the maximum depths of 62 feet and 36 feet respectively. The Tippecanoe River serves as

the Lake’s outlet. The lakes have a watershed of 71,660 acres (112 square miles), 50% of the land use within the

watershed is agriculture (J.F. New 1997). Thirty percent of the watershed is considered highly erodible land. Highly

erodible land is very susceptible to erosion, including soils with a natural erosion potential of at least eight times their

tolerable limit as established by the United States Department of Agriculture. The 1997 Lake Tippecanoe Diagnostic

Study the need for dredging due to high phosphorus levels and resuspension of high phosphorus sediments from

boating activities in shallow lake areas which can be observed annually within the area referred to as Tippe

Channel/Hoys Landing/Hanna B Walker, and may have a negative effect on the establishment of the Lake Tippecanoe

EcoZone. LTPO is involved with ongoing Aquatic Vegetation Management, Figure 4 is a map with the locations of Lake

Tippecanoe Eurasian watermilfoil and curlyleaf pondweed treatment areas, April 30, 2012. (Aquatic Control 2013).

3.3 Potential Sediment Removal Areas

Individual maps and measurements for these areas are located in Appendix A. Planned sediment removal to natural

lakebed or previously dredged lake bottom.

Area 1 – Shoshoni Inlet (Channelized Tippecanoe River inlet)

This area is located on the east side of James Lake (Little Tippy). This is the channelized portion of the Tippecanoe River

inlet into James Lake, Lake Tippecanoe and Oswego Lake. Lake users have noted a reduction in the water depth at this

location. The channel separates two large beds of water lily/spatterdock, dredging is recommended to avoid the beds

of floating plants. The recommended dredging area will remove a deposition of fine silt and organic matter averaging

1.9 feet. The dredging area is approximately 320’ X 55’ (20’ wide in channel, fans out to 115’ on west end).

Area 2 –Channel at James Lake (Two parts A –east and B – west)

Page 17: LTPO Sediment Removal Plan Final edits 122013 · 2014-01-17 · Lake Tippecanoe/James Lake/Oswego Lake Sediment Removal Plan January 2013 Kosciusko County, Indiana Lake Tippecanoe

Lake Tippecanoe/James Lake/Oswego Lake Sediment Removal Plan January 2013 Kosciusko County, Indiana

Lake Tippecanoe Property Owners Association 11 Williams Creek Consulting, Inc.

This area is made up of two segments of the James Lake inlet into the channel between James Lake and Lake

Tippecanoe, part A – east and B - west. Lake users report a reduction in water depth in places throughout the channel.

Most boaters stop their boats when exiting the channel to reverse their motors and increase the throttle to remove

weeds. This action causes an additional resuspension of sediment. The recommended dredging area will avoid the

beds of floating plants on the sides of the channel. The sediment in both areas is composed of fine silt and organic

material. The sediment deposition on the A - east end is 1 feet deep across an area 270’ X 78’ (40’ in channel, fans out

to 135’ on east end). The sediment deposition in the second area B – west within the channel is 0.9 foot deep across an

area 270’ X 40’.

Area 3 – 3A - Channel from Tippe to James Lake and 3B - Hanna B. Walker Delta Area

This area is made up to two segments 3A - Channel from Tippe to James Lake located on the Lake Tippecanoe end of

the channel between Lake Tippecanoe and James Lake. 3B - Hanna B. Walker Delta Area located between 3A and the

Hanna B. Walker Inlet. Lake users report a reduction in water depth in places throughout the channel between the

lakes and in the general area west of the channel inlet. Many unsuspecting boaters become stuck in the shallow depth

combined with the large amount of algae in this area. Most boaters stop their boats when exiting the channel to

reverse their motors and increase the throttle to remove weeds. This action causes an additional resuspension of

sediment. Prevailing winds in the area are predominately from the SW (Global Energy Concepts, 2005), pushing any

vegetation uprooted by boating, algae mats, and resuspended sediment into this area. The recommended dredging

area will avoid the beds of floating plants on the sides of the channel and on the north side of the channel at the inlet.

The sediment deposition in this area is composed of fine silt and organic material. The average sediment depth in area

3A is 2.0 feet, the area covers 1.79 acres. The average sediment depth in area 3B is 2.5 feet, the area covers 1.43 acres.

Additional sediment depths measured by IDNR in an area not accessible in the boat Williams Creek used during

measurements are included in the sediment calculations.

Area 4 – Hanna B. Walker Inlet/Sediment Trap

Hanna B. Walker Inlet/Sediment Trap is located north of area 3B - Hanna B. Walker Delta Area on the north side of the

east basin of Lake Tippecanoe. The channel is the downstream outlet of the Hanna B. Walker drain. Measures have

been implemented in the watershed of this drain and within the drain to reduce sediment inflow into Lake Tippecanoe.

A sediment trap was installed north of the Hanna B. Walker Inlet by LTPO in 1991, an additional sediment trap was

installed in the channel based on a LARE design in 2000. The Hanna B. Walker Inlet and the sediment trap have been

dredged previously in 1994, 2000, and 2006. The recommended dredging area will remove a deposition of fine silt and

organic matter averaging 4.5 feet. The dredging area is approximately 0.19 acres. LTPO will need to establish firm

limits (distances) for the dredger to stay away from seawalls.

Area 5 – Hoys Landing

Hoys Landing is located on the north side of the east basin of Lake Tippecanoe. Lake users have noted a reduction in the

water depth at this location. The dredging proposed in this area will return the area to the natural lakebed. This area is

affected by boating activities and prevailing winds pushing any vegetation uprooted by boating, algae mats, and

resuspended sediment into this area. The recommended dredging area will remove a deposition of fine silt and organic

matter averaging 0.8 feet. The dredging area is approximately 575’ X 160’. Williams Creek and LTPO believe this

sediment and decaying algae in this area are from resuspension of sediment during boating season and prevailing

winds. Additional analysis of this area is recommended, such as Secchi disc readings prior to and during boating

season. If this area is not suitable for dredging LTPO may want to consider mechanical harvesting using a system

similar to the Aquamarine system used by Aquatic Weed Control in Syracuse, Indiana.

Area 6 – Tippecanoe Boat Company SW to Pier

This area is located on the north side of the east basin of Lake Tippecanoe. This area extends from the inlet of the

Tippecanoe Boat Company channel to the west side of the pier at the Beer residence. Property owners have

documented a reduction in the water depth at this location. The recommended dredging area will remove a deposition

of fine silt and organic matter averaging 1.4 feet. The dredging area is approximately 320’ X 55’.

Area 7 – Grassy Creek Inlet

This area is located on the south side of the east basin of Lake Tippecanoe, this is the inlet of Grassy Creek into the lake.

This channel is also the outlet for the Lakeview Terrace Mobile Home Park. Lake users report a reduction in water depth

at the inlet of the channel. Most boaters stop their boats when exiting the channel to reverse their motors and

increase the throttle to remove weeds. This action causes an additional resuspension of sediment. The recommended

dredging area will avoid the beds of floating plants on the sides of the channel. The recommended dredging area will

remove a deposition of fine silt and organic matter averaging 1.5 feet. The dredging area is approximately 320’ X 55’.

Area 8 – Ducunee Channel

Ducunee Channel is a private channel on the south side of the east basin of Lake Tippecanoe. Channel users report a

reduction in water depth in the channel. The deepest sediment in the channel is approximately 150 feet south of the

inlet. This area is believed to be where wave action from incoming boats dissipates allowing suspended sediment to

settle. Upon exiting the channel, most boaters stop their boats to reverse their motors and increase the throttle to

remove weeds. This action causes an additional resuspension of sediment. The recommended dredging area will

remove a deposition of fine silt and organic matter averaging 1.3 feet. The dredging area is approximately 990’ X 75’.

The channel owners will need to contract with the dredging company based on their schedule with public dredging

projects. The channel owners need to establish firm limits (distances) for the dredger to stay away from seawalls.

report a reduction in water depth in the channel. The deepest sediment in the channel is approximately 125 feet east

of the inlet. This area is believed to be where wave action from incoming boats dissipates allowing suspended

sediment to settle. Upon exiting the channel, most boaters stop their boats to reverse their motors and increase the

throttle to remove weeds. This action causes an additional resuspension of sediment. The recommended dredging area

will remove a deposition of fine silt and organic matter averaging 1.4 feet. The dredging area is approximately 100’ X

70’, with an additional lagoon area 162’ X 300’. The channel owners will need to contract with the dredging company

based on their schedule with public dredging projects. The channel owners need to establish firm limits (distances) for

the dredger to stay away from seawalls.

Area 12 – Paton Point Inlet

Paton Channel is a private channel on the north side of the center section of Lake Tippecanoe. A pipe outlets into the

channel near Kalorama Road, the drainage area for the pipe appears to be 8-10 acres on the north side of Kalorama

Road. Channel users report a reduction in water depth in the channel and the inlet. The deepest sediment in the

channel is just north of the inlet and the inlet itself. Build up in this area is believed to be where wave action from

incoming boats dissipates allowing suspended sediment to settle. Pier configuration seems to be compounding the

problem at the inlet. Upon exiting the channel, most boaters stop their boats to reverse their motors and increase the

throttle to remove weeds. This action causes an additional resuspension of sediment. The recommended dredging area

will remove a deposition of fine silt and organic matter averaging 1.5 feet. The dredging area is approximately 450’ X

Area 17 – Bellrohr Isle (Two parts A -west and B - east)

This area is located on both side of the culvert on EMS T 30, on the north side of Oswego Lake. Lake users report a

reduction in water depth in places throughout the channel. Most boaters stop their boats when exiting the channel to

reverse their motors and increase the throttle to remove weeds. This action causes an additional resuspension of

sediment. The sediment is composed of fine silt and organic material. The sediment deposition on the A -east end is

1.5 feet deep across an area 820’ X 70’. The sediment deposition on the B – west

Area 18 – Woods Channel

Woods Channel is a private channel on the east side of the Oswego Lake. Channel users report a reduction in water

depth in the channel. The deepest sediment in the channel just before the EMS T26 bridge east of the inlet. This area

is believed to be where wave action from incoming boats dissipates allowing suspended sediment to settle. Upon

exiting the channel, most boaters stop their boats to reverse their motors and increase the throttle to remove weeds.

This action causes an additional resuspension of sediment. The recommended dredging area will remove a deposition

of fine silt and organic matter averaging 1.2 feet. The dredging area is approximately 995’ X 75’. The channel owners

will need to coordinate dredging of the area near the footers of the bridge with the Kosciusko County Highway

Superintendent. Any requirement made by the county will need to written into the contract with the dredging

company. The channel owners will need to contract with the dredging company based on their schedule with public

dredging projects. The channel owners need to establish firm limits (distances) for the dredger to stay away from

seawalls and bridge footers. Sediment disposal area will be on the Ted Workman property on the south end of the

channel.

3.4 Land Agreements

Sediment disposal sites have been proposed for the project based on geographical areas to the proposed sediment

removal sites. Various sites are required and are illustrated in Figure 5. Verbal commitment for three of the sites, two

other landowners have signed agreements for previous projects. A landowner agreement will be in place when funding

is secured for a project site. Landowner agreements for the sediment disposal sites are included in Appendix C. The

sediment disposal sites will be constructed by the dredging contractor, the contractor will be responsible for any

permits required by the construction activities. LTPO will be responsible for completing easements or land agreements.

Lake Tippecanoe Property Owners Association 16 Williams Creek Consulting, Inc.

Figure 5: Potential Sediment Disposal Sites

4.0 CONSTRUCTION CRITERIA

4.1 Sediment Removal Method

The method proposed for sediment removal is hydraulic dredging. Dredged sediment will be transported via an eight

(8) inch diameter pipe to the disposal site. A hydraulic dredge floats on the water and excavates and pumps the

material through a temporary pipeline to an offsite location, often several thousand feet away. This dredge acts like a

floating vacuum cleaner that can remove sediment very precisely. The dredge and dredge discharge line cause very

little disruption to the shoreline.

4.2 Contractor Selection

The bid process and contractor selection will be administered by the LTPO who will select the contractor who is best

qualified for the project. LARE staff will assist the LTPO in this process by conducting a pre-bid meeting with

contractors. The LTPO Aquatic Weed Control and Dredging Committee will be in charge of completing the future

dredging project(s) LTPO will decide if they will utilize a volunteer with an engineering background to oversee the

project or possibly hire someone to provide oversight as part of the grant.

4.3 Spoil Disposal

Sediment disposal areas or dewatering areas will be constructed based on the geographical area of the dredging

activities. The dewatering areas will be constructed in an upland location with a designated outlet. Topsoil will be

removed and stockpiled with stabilization. Additional soil will be excavated and used to construct berms with 2:1 side

Page 23: LTPO Sediment Removal Plan Final edits 122013 · 2014-01-17 · Lake Tippecanoe/James Lake/Oswego Lake Sediment Removal Plan January 2013 Kosciusko County, Indiana Lake Tippecanoe

Lake Tippecanoe/James Lake/Oswego Lake Sediment Removal Plan January 2013 Kosciusko County, Indiana

Lake Tippecanoe Property Owners Association 17 Williams Creek Consulting, Inc.

slopes around the entire basin. Berms should be constructed in six inch lifts and compacted to 90% modified proctor.

The dewatering basin will be sized according to the area or combination of areas to be dredged, while also

accommodating the space needed for dewatering.

During construction of the berm and throughout the dredging project, erosion control practices will be implemented to

prevent sediment from entering the lakes. Temporary seeding will be used on any disturbed areas. Silt fence and/or coir

log will be used to capture any sediment prior to water returning to the lakes. Similarly, the outlet for return water will

be armored to prevent erosion. After completion of the project, the dewatering basin will be capped to create a smooth

finish grade. Establishment of vegetation on the side slopes and finished top grade of the basin will prevent erosion.

4.4 Permitting

Permitting will be the responsibility of the LTPO or contractor. Dredging will require early coordination with IDNR

biologists and IDNR Division of Water Lake Preservation Permit for the affected areas.

A Rule 5 Stormwater Pollution Prevention Plan Permit from the Indiana Department of Environmental Management

(IDEM) will be required for any land disturbance activity greater than one (1) acre in size. The contractor constructing

the berm will be responsible for obtaining this permit prior to any earth moving activities.

Because Lake Tippecanoe is located within the area identified as FEMA Flood Zone AE, a Construction in a Floodway

Permit from the IDNR may be acquired based on final location of sediment disposal and dewatering area prior to the

beginning of dredging activities.

Sections 404 and 401 of the Clean Water Act regulate the discharge of dredged or fill material into “waters of the U.S.”

Dredging conducted hydraulically or through excavation, where no dredged material is re-deposited within the water

body, is considered “one step removal” by the US Army Corps of Engineers (USACE) and IDEM. Dredging via one-step

removal does not require a permit from the USACE and IDEM. However, it is recommended notification of these

regulatory agencies of intent to conduct one-step removal prior to project initiation. Disposal of dredge spoils in a

wetland area would require coordination with the USACE and/or IDEM.

A Regional General Permit (RGP) and Water Quality Certification (WQC) will likely be required for Installation of a pipe to

discharge return water to the lakes. If anticipated impacts resulting from such actions are 1.0 acre or greater or exceed

150 lf of stream, then an Individual Permit (IP) may be necessary. Mitigation for impacts is required at a 1:1 ratio for

drainage features and open water, 4:1 for forested wetlands, 3:1 for scrub/shrub wetlands, and 2:1 for emergent

wetlands if verified as a USACE jurisdictional “waters of the U.S.”

As part of the early coordination process, on October 1, 2013 the sites were looked at with IDNR representatives Doug

Nusbaum and Nate Thomas. The following comments are input from the IDNR Lakes Biologist.

11/07/2013 Areas 8, 9, 10, 11, 12, 15, and 18: Manmade, dead-end channels. Cleared for environmental review during permitting phase. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase. Area 1: Shoshoni inlet, Tippy River – A delta lakeward of the Shoshoni inlet is proposed to be dredged. This area is characterized by large beds of emergent vegetation near the proposed dredging area. However, the area identified to be dredged appears to avoid any impacts to emergent vegetation and other beneficial habitat for fish and wildlife. In addition, NRC Information Bulletin #60, the Department’s Non-rule Policy Document that provides guidance on dredging in public freshwater lakes, states that dredging may be approvable where a project aims to restore the original depth by removing a delta lakeward of an inlet. Therefore, I recommend that this area be cleared for environmental review for permitting. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase. Area 2: Tippy Channel at James Lake- This area is located within a navigation channel between James (Little Tippy) and Lake Tippecanoe. The Division of Fish and Wildlife does not oppose restoring depths in navigational channels to improve public boat access. Still, margins of the channel are lined with emergent vegetation such as white water lily, spatterdock, and cattails. Efforts should be made to avoid impacting these areas of sensitive fish and wildlife habitat. Figures submitted for review appear to show emergent vegetation beds will not be dredged as a part of this project. Therefore, the Division of Fish and Wildlife recommends that Area 2 be cleared for environmental review. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase. Area 3: Tippy Channel, Hanna B. Walker, Hanna B Walker sediment trap- This area is located along the northeast end of Tippecanoe Lake near the navigational channel to James Lake. Similar to area 2, the Division of fish and wildlife does not oppose dredging within the navigational channel so long as impacts to emergent vegetation are avoided. The Hanna B Walker inlet is located to the northwest of the navigation channel. This area is characterized by accumulated sediment and shallow areas lakeward of the inlet. Accumulated sediment is also present within the inlet and is also proposed to be dredged. Similar to area 1, the Division of Fish and Wildlife does not oppose removing accumulated sediments associated with a delta located lakeward of an inlet. However, data points submitted as a part of this plan are limited, especially in areas between the inlet and navigation channel. The Division of Fish and Wildlife conducted sediment probing in this area in 2012 and 2013. Data analysis of sediment probing in this area suggests a large amount of sediment has been deposited lakeward of and to the east of the inlet in areas where data was not collected by Williams Creek. As much as 4 ft of sediment was measured during the 2013 site visit. Notably, the majority of this area was historically dredged over many events. Overall, accumulated sediment is present within the proposed “Area 3” and the Division of Fish and Wildlife recommends environmental clearance for review during the permitting phase of this project. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase. Area 4: Lasalle channel. See notes above regarding Hanna B Walker inlet. The Division of fish and wildlife does not oppose dredging in this area as accumulated sediment has been identified and is associated with anthropogenic inputs from the inlet. In addition, this area was also historically dredged under various permits. Overall, accumulated sediment is present within the proposed “Area 4” and the Division of Fish and Wildlife recommends environmental clearance for review during the permitting phase of this project. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase.

Area 5: Hoy’s Landing. Hoy’s landing is located to the west of the Hanna B Walker inlet. Due to prior interest in dredging this area, sediment probing was conducted by Division of Fish and Wildlife staff of November, 2012. No accumulated sediment was found in this area at that time. However, upon receipt of the sediment removal plan, additional sampling was conducted in 2013 throughout the proposed project area. Again, no accumulated sediment was found. Alga was dense in this area and was approximately 6 inches in thickness. However, a solid, sandy bottom was found immediately below this algal layer. Submerged vegetation- mostly Eurasian watermilfoil, sago pondweed, curlyleaf pondweed, and eelgrass- was dense near the location of a group pier associated with Hoy’s Landing. Vegetation and algae may be a nuisance for boating in this area; however, Information Bulletin #60 states dredging may not be approvable where its purpose is to “remove solely aquatic vegetation where lawful dredging did not previously occur.” Notably, aquatic vegetation and algae may be controlled under an Aquatic Vegetation Control permit that is subsequently reviewed by fisheries staff. Information Bulletin #60 also states dredging may not be approvable where it aims to “increase water depth in naturally shallow areas to improve boat access, unless anthropogenic actions contributed to a reduction in natural water depth.” Because sampling yielded no evidence of accumulated sediment or anthropogenic sources for sediment it appears this proposal is inconsistent with Information Bulletin #60. Therefore, the Division of Fish and Wildlife cannot support dredging in Area 5. Inclusion in permitting reviews may result in denial of a permit. Area 6: Tippecanoe Boat Company inlet southwest to pier. This area is located to the west of the channel to the Tippecanoe Boat Company. In addition to data submitted in this plan, sediment sampling was conducted by Division of Fish and Wildlife staff to determine the presence of accumulated sediment in this area. Sediment sampling showed that sediment/organic debris is present in this area; however, no evidence has been shown to suggest that this are is not naturally shallow and anthropogenic sources have contributed to the accumulation of sediment in this area. Therefore, the Division of Fish and wildlife recommends environmental clearance for dredging in Area 6 but more information- including likely source of sediment accumulation- be presented during the permit review phase. Area 7: Grassy Creek inlet. A small area is proposed to be dredged at the inlet of Grassy Creek into Lake Tippecanoe. This area was previously dredged in 2001. Emergent vegetation is present near the project site but does not appear to be impacted by the proposed dredging. The Division of Fish and Wildlife recommend environmental clearance for dredging in Area 7 during the permitting phase of this project. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase. Area 13: Indiana Creek inlet. A small delta is proposed to be dredged lakeward of the Indiana Creek inlet to Tippecanoe Lake. Sand and organic debris have accumulated above the water surface in this area. Emergent vegetation or other beneficial habitat is not abundant near the project site. If dredging is approved in this area, efforts should be made to taper the dredging to the natural lakebed contour. Overall, the Division of Fish and Wildlife recommends environmental clearance for review of Area 13 during the permitting phase of this project. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase. Area 14: Old Mill Place. This area is a small cove located near Old Mill addition on Tippecanoe Lake. The cove opens into two manmade channels that are connected by various culverts. Concrete seawalls are present around the entire project area. Sediment sampling conducted by Division of Fish and Wildlife staff showed a significant amount of sediment has accumulated in this cove. Though no evidence has been provided to suggest the sediment has accumulated due to anthropogenic sources, it is not unlikely that this low-energy cove collects sediment from the main body of the lake and allows it to deposit. Emergent vegetation in the form of white water lily is present within the cove but is not likely to be impacted given the proposed dredging area. Overall, the Division of Fish and Wildlife recommends environmental clearance for review of Area 14 during the permitting phase of this project. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase.

Area 16: Oswego Channel. This area is located towards the north shoreline at the junction of Lake Tippecanoe and Oswego Lake. This area appears to be a historically-shallow area that not been previously dredged. Submerged vegetation, primarily eelgrass, presents a nuisance for boating in this area. Though sediment has been documented, there is no evidence to suggest that sediment has accumulated in this area due to anthropogenic inputs. Information Bulletin #60 states dredging may not be approvable in naturally shallow areas that have not been historically dredged or as a means to remove aquatic vegetation. Eelgrass or other nuisance vegetation may be treated under a Vegetation Control Permit that is subsequently reviewed by fisheries staff. Other concerns about public safety have also been expressed since this is a shallow area that is traveled over regularly. Safety concerns should be expressed to local conservation officers. Placement of bouys or other warning devices may be helpful in this area. Still, the Division of Fish and Wildlife cannot support dredging in a historically shallow area and where dredging will primarily remove aquatic vegetation. Inclusion in permitting reviews may result in denial of a permit. Area 17: Bellrohr Isle channel. Area 17 is located within a manmade, u-shaped channel near Bellrorh isle/ EMS T30 Ln. Two culverts connect the channel under the lane. Due to the low-energy properties of the area, sediment has accumulated near both sides of the culvert. One culvert shows significant blockage due to accumulated sediment. The Division of Fish and Wildlife does not oppose dredging within the manmade channel and recommends Area 17 be cleared for environmental review for permitting. Please note, clearance for environmental review does not imply approval of any future permit or project. Additional information may be required during the review phase.

4.5 Construction Schedule

It is anticipated dredging activities will take place over a series of years due to the magnitude of investment. The LTPO

Aquatic Weed Control and Dredging Committee will be in charge of the funding and prioritizing sites based upon the

recommendations of IDNR and data from this plan.

In the first series of dredging, the anticipated schedule includes construction of the dewatering basin on the selected

disposal site is anticipated to begin in spring 2014 assuming funding is available through LTPO and IDNR. Dredging of

the proposed site would begin following completion of the dewatering basin (spring or summer 2014). Contingent

upon date of project initiation, dredging is anticipated to be completed by fall 2014. Final grading of the sediment

dewatering basin is anticipated to be complete in fall 2015. Additional sites in subsequent years would follow a similar

schedule.

4.6 Cost Estimate

A cost estimate for the proposed sediment removal was assembled from information collected by the LTPO and

Williams Creek. Price estimates ranged from $17.00 to $22.00 per cubic yard of material removed. This cost included

mobilization fees, cost of constructing the dewatering area, and dredging activities. If a dewatering bag was needed in

place of the dewatering basin, the fee would be $25.00 per cubic yard. This information is summarized in the following

table.

Area 1 – Shoshoni Inlet

 

Area 1 – Shoshoni Inlet (Channelized Tippecanoe River inlet)

This area is located on the east side of James Lake (Little Tippy). This is the channelized portion of the Tippecanoe River inlet into James Lake, Lake Tippecanoe and Oswego Lake. Lake users have noted a reduction in the water depth at this location. The channel separates two large beds of water lily/spatterdock, dredging is recommended to avoid the beds of floating plants. The recommended dredging area will remove a deposition of fine silt and organic matter averaging 1.9 feet. The dredging area is approximately 320’ X 55’ (20’ wide in channel, fans out to 115’ on west end).

Area 2 –Channel at James Lake (Two parts A –east and B – west)

Area 2 –Channel at James Lake (Two parts A –east and B – west)

This area is made up of two segments of the James Lake inlet into the channel between James Lake and Lake Tippecanoe, part A – east and B - west. Lake users report a reduction in water depth in places throughout the channel. Most boaters stop their boats when exiting the channel to reverse their motors and increase the throttle to remove weeds. This action causes an additional resuspension of sediment. The recommended dredging area will avoid the beds of floating plants on the sides of the channel. The sediment in both areas is composed of fine silt and organic material. The sediment deposition on the east end is 1 feet deep across an area 270’ X 78’ (40’ in channel, fans out to 135’ on east end). The sediment deposition in the second area within the channel is 0.9 foot deep across an area 270’ X 40’.

Area 3 – 3A - Channel from Tippe to James Lake and 3B - Hanna B. Walker Delta Area

This area is made up to two segments 3A - Channel from Tippe to James Lake located on the Lake Tippecanoe end of the channel between Lake Tippecanoe and James Lake. 3B - Hanna B. Walker Delta Area located between 3A and the Hanna B. Walker Inlet. Lake users report a reduction in water depth in places throughout the channel between the lakes and in the general area west of the channel inlet. Many unsuspecting boaters become stuck in the shallow depth combined with the large amount of algae in this area. Most boaters stop their boats when exiting the channel to reverse their motors and increase the throttle to remove weeds. This action causes an additional resuspension of sediment. Prevailing winds in the area are predominately from the SW (Global Energy Concepts, 2005), pushing any vegetation uprooted by boating, algae mats, and resuspended sediment into this area. The recommended dredging area will avoid the beds of floating plants on the sides of the channel and on the north side of the channel at the inlet. The sediment deposition in this area is composed of fine silt and organic material. The average sediment depth in area 3A is 2.0 feet, the area covers 1.79 acres. The average sediment depth in area 3B is 2.5 feet, the area covers 1.43 acres. Additional sediment depths measured by IDNR in an area not accessible in the boat Williams Creek used during measurements are included in the sediment calculations.

Area 4 – Hanna B. Walker Inlet/Sediment Trap

Hanna B. Walker Inlet/Sediment Trap is located north of area 3B - Hanna B. Walker Delta Area on the north side of the east basin of Lake Tippecanoe. The channel is the downstream outlet of the Hanna B. Walker drain. Measures have been implemented in the watershed of this drain and within the drain to reduce sediment inflow into Lake Tippecanoe. A sediment trap was installed north of the Hanna B. Walker Inlet by LTPO in 1991, an additional sediment trap was installed in the channel based on a LARE design in 2000. The Hanna B. Walker Inlet and the sediment trap have been dredged previously in 1994, 2000, and 2006. The recommended dredging area will remove a deposition of fine silt and organic matter averaging 4.5 feet. The dredging area is approximately 0.19 acres. LTPO will need to establish firm limits (distances) for the dredger to stay away from seawalls.

Area 18 – Woods Channel

Woods Channel is a private channel on the east side of the Oswego Lake. Channel users report a reduction in water depth in the channel. The deepest sediment in the channel just before the EMS T26 bridge east of the inlet. This area is believed to be where wave action from incoming boats dissipates allowing suspended sediment to settle. Upon exiting the channel, most boaters stop their boats to reverse their motors and increase the throttle to remove weeds. This action causes an additional resuspension of sediment. The recommended dredging area will remove a deposition of fine silt and organic matter averaging 1.2 feet. The dredging area is approximately 995’ X 75’. The channel owners will need to coordinate dredging of the area near the footers of the bridge with the Kosciusko County Highway Superintendent. Any requirement made by the county will need to written into the contract with the dredging company. The channel owners will need to contract with the dredging company based on their schedule with public dredging projects. The channel owners need to establish firm limits (distances) for the dredger to stay away from seawalls and bridge footers. Sediment disposal area will be on the Ted Workman property on the south end of the channel.
