Targeted Stormwater Retrofit Project for Highly Sensitive Island-Loon Lake
The Crow Wing County (CWC) Water Plan identifies Island-Loon Lake as a priority lake to enhance due to its significant decline in water clarity and high ratio of impervious surface surrounding the lake. To mitigate the runoff, the Crow Wing Soil and Water Conservation District will partner with the CWC HWY Department, City of Crosslake, Crosslakers, and Whitefish Area Property Owners Association to install three mechanical separators and 13,500 square feet bioretention area that will reduce six pounds of phosphorus and 1 ton of sediment per year from entering the lake.

for grants 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 these funds may be used to seek administrative efficiencies through shared resources by multiple local governmental units.
This project will install three mechanical separators and a 13,500 square bioretention basin that will reduce six pounds of phosphorus and 1.2 tons of sediment per year from entering Island-Loon Lake.
This project has resulted in an estimated annual reduction of 4.7 pounds of Phosphorus, 1.1 tons of Sediment. The following were also completed. A Stormwater Pond, 5,1161,17 square feet of area, installed Hydrodynamic Separator (HS 103) Diameter 5', Hydrodynamic Separator HS 200( Diameter 8', as pre-treatment to the stormwater pond. Along the westside of 66 installed a Hydrodynamic separator-HS 400. The contractor planted 19 Spruce trees, 20 American Hazelnut, and 20 Wild Plum adjacent to the stormwater pond.
