ABOUT NORMANDALE LAKE
Normandale Lake is a 112-acre waterbody in Bloomington, providing opportunities for walking, biking, picnicking, and boating. The lake was created in 1979 to help control downstream flooding. Nine Mile Creek flows through the lake on its way to the Minnesota River.
DID YOU KNOW?
Normandale Lake was created by the District in partnership with the City of Bloomington in 1979 to control flooding. It proved its worth in the 1987 superstorm. While parts of 494 were under 13 feet of water, Normandale Lake prevented considerable downstream damage by containing extra water.
Normandale Lake is a shallow lake, which means aquatic plants naturally grow throughout the lake. The lake is not on the state’s impaired waters list for nutrients. However, due to the large, urban nature of the area that drains to Normandale Lake, it receives a lot of nutrient pollution. Nutrient pollution is when too many nutrients, like phosphorus, act like fertilizer and contribute to excessive algal growth.
The District conducted a fish survey on Normandale Lake during the summer of 2018 to determine the carp population in the lake and understand the fisheries community of the lake.
Normandale Lake Water Quality Improvement Project
To improve the health of Normandale Lake, the District and City of Bloomington will conduct a lake-level drawdown, selective herbicide treatment, and alum treatment. The project will occur August 2018-spring 2019.
How can you help?
Because Normandale Lake suffers from nutrient pollution, keep grass clippings, leaves, and fertilizer out of the street and stormdrains. These things feed algae.
