ABOUT LAKE CORNELIA

Lake Cornelia is a shallow lake in a natural marsh area. This lake is rich in nutrients. Algal blooms in the summer have offered more limited uses of the lake. The District conducted projects during 2019-2020 to improve the health of Lake Cornelia and Lake Edina. The Minnesota Department of Natural Resources stocks the lake for its Fishing in the Neighborhood Program.

Water Quality

Curly-leaf-pondweed
Curly-leaf pondweed

Due to high levels of nutrients, the lake’s water quality has consistently been poor. Nutrients coming from the surrounding watershed feed algae in the summer, leading to low water clarity. Curly-leaf pondweed has also become problematic since 2015.

What can you do to help?

Sweep leaves and grass clippings out of the street. These materials contain nutrients that make algae grow. By keeping them out of the street, they won’t wash down stormdrains and into the lake. This will help reduce how much algae grows in the lake.
