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.
Use Attainability Study (UAA) Update
A UAA provides a scientific foundation for lake-specific best management plans through assessment of a lake’s physical, chemical, and biological condition. Previous UAA versions (2006 and 2010) exist for Lake Cornelia. The District conducted a study of the lakes in 2018-2019 to help address the poor water quality in Lake Cornelia and Lake Edina. The District implemented projects in 2019-2020 to improve the health of the lakes, including conducting an alum treatment in the spring of 2020 on Lake Cornelia.
Lake Cornelia & Lake Edina Water Quality Improvement Project
The Nine Mile Creek Watershed District will conduct projects during 2019-2020 to improve the health of Lake Cornelia and Lake Edina. For more information about the projects, visit the the project page.
The Nine Mile Creek Watershed District and the City of Edina have hosted community meetings in the past to inform residents about studies and upcoming projects on Lake Cornelia and Lake Edina. There are no meetings scheduled currently; please contact Gael to be put on the mailing list for future community meetings.

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.
