Phase 1 of Five Mile Creek and Marsh Lake Improvement Strategy
The proposed project is: Phase 1 of the Five Mile Creek and Marsh Lake Improvement strategy. The Big Stone SWCD plans to install 30-40 WASCoBs and other alternative practices like cover crops, no till/strip till, etc. within the Five Mile Creek watershed. Currently, 19-shovel ready WASCoBs have been designed with plans of reaching out to other landowners to implement similar practices. Using PTMapp, we will identify areas with medium to high sediment loss and target those landowners to implement projects. As identified in the Targeted Implementation Plan, a total reduction goal of 25 percent (3,439 tons) sediment and 12 percent (939 lbs) phosphorous is needed in County Ditch 2 and a reduction goal of 25 percent sediment (16,551) and 15 percent (8485 lbs) phosphorous reduction is needed for Marsh Lake. After calculating sediment and phosphorous savings in PTMapp (19 designed basins basins), we would expect to get 15 percent closer to the reduction goal for sediment and 9 percent closer for phosphorous, as identified for County Ditch 2 (Five Mile Creek). Furthermore, we would see an overall reduction of 3 percent sediment and 1 percent phosphorous toward reduction goals for Marsh Lake. Unfortunately, Phase 1 of this project does not get us all the way there, but it is a significant step in the right direction for Five Mile Creek and Marsh Lake.

(b) $16,000,000 the first year and $16,000,000 the second year are for grants to local government units to protect and restore surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of this money may be used to seek administrative efficiencies through shared resources by multiple local governmental units. Up to 20 percent of this appropriation is available for land-treatment projects and practices that benefit drinking water.
As calculated using PTMapp (19 pre-designed basins), a total reduction of 532.6 tons of sediment and 89.1 lbs of phosphorous, annually.
The total proposed measurable goals were not achieved since the overall project design was altered. Instead of 19 basin the project only needed 12 basins in order to achieve the infield erosion goals and gain landowner support, thus the overall reduction estimates were less than projected since the number of basins were less. Also, a different calculation toll was used to generate reduction estimates once the project was completed. Overall reduction estimates calculated at the time of completion are 352.08 lbs/yr of Phosphorus and 1776.93 T/yr for soil savings.
