Casey Lake Neighborhood Stormwater Retrofit
Ramsey-Washington Metro Watershed District (RWMWD) will improve water quality in Casey Lake and ultimately Kohlman Lake through the installation of approximately 25 rain gardens on priority properties identified as part of the Casey Lake Urban Stormwater Retrofit Assessment completed by Ramsey Conservation District (RCD) in 2011. Capturing and filtering stormwater through rain garden installation within the 208 acre Casey Lake Neighborhood will provide a unique opportunity to target a significant source of phosphorus to one of Minnesota's impaired waters while educating residents on the importance of the role they share in improving stormwater quality.
Despite its name, Casey Lake is actually a 15.2 acre lacustrine wetland and is part of the Kohlman Creek Subwatershed which drains to Kohlman Lake. Kohlman Lake, which is the headwater of the Phalen Chain of Lakes, is currently listed on the Minnesota Pollution Control Agency's (MPCA) 2012 Impaired Waters List for excess phosphorus. This project will help to meet the phosphorus reduction goals laid forth in the Kohlman Lake Total Maximum Daily Load (TMDL) Implementation Plan.
