Wassermann Lake is categorized as a recreational lake.  During the spring and fall the lake is generally safe and provides wonderful boating, fishing and other recreational opportunities.  However, as the temperatures rise the lake quickly becomes unhealthy when excessive nutrients in the lake cause major algae blooms.  The Wassermann Lake Association was formed in 2011 to work closely with property owners, the city and Minnehaha Creek Watershed District (MCWD) to maintain focus on improving the lake quality. Fortunately, our lake quality will be improving as the MCWD implements it's lake management plans over the next few years. Please join your neighbors as we continue to partner to improve our lake.  This website provides an overview of these efforts and resources to learn the steps you can take to reduce runoff into the lake.
