Taft-Legion Volume and Load Reduction Project
Minnehaha Creek Watershed District (MCWD) partnered with the City of Richfield to improve the water quality in Taft Lake and Legion Lake through a combination of project elements, including infiltration systems, a water treatment system to treat water from Taft Lake, native lakeshore buffers, and pre-treatment of runoff to Legion Lake. These strategies improve water quality by treating and filtering stormwater runoff and reducing the nutrient load in both Taft and Legion lakes, both of which drain into Lake Nokomis and ultimately Minnehaha Creek.
The City of Richfield led the design and construction of the project and manages ongoing operations and maintenance, while MCWD provided financial assistance for the design and construction.

native prairie established along Legion Lake
- Habitat enhancement through the establishment of native prairie
- Reduced runoff volume to downstream Lake Nokomis
- Nutrient load reduction in Taft and Legion lakes
- Improved water quality for Lake Nokomis
In 2011, MCWD and the City of Richfield signed a Memorandum of Understanding (MOU) identifying the City’s desire to construct and operate a regional stormwater treatment facility. In 2013, MCWD and the City of Richfield signed a Cooperative Agreement to construct, operate, and maintain this water quality improvement project for Legion and Taft Lakes.
Project Cost: $2,654,387
MCWD funded the entirety of this project’s construction, and the City of Richfield maintains and operates the treatment systems.
