A UAA provides a scientific foundation for lake-specific best management plans through assessment of a lake’s physical, chemical, and biological condition.┬áPrevious UAA versions (2006 and 2010) exist for Lake Cornelia. In 2018, the District will update the Lake Cornelia UAA with the most recent watershed and in-lake models and by evaluating water quality monitoring data that has been collected since 2010. Lake and watershed best management practices will be evaluated, based on collaboration with City of Edina staff and stakeholder input.

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.
