In 2006, the District completed construction on three stormwater detention ponds to treat stormwater before it reached Glen Lake. The goal of this project was to reduce phosphorus entering Glen Lake.

Project Details

The Glen Lake project focused on cleaning stormwater runoff before it drained to Glen Lake.

These improvements were part of the larger Minnetonka Lakes Water Quality Improvement Project. The Use Attainability Analysis (UAA) for Glen Lake guided the development of this project. The UAA determined that about half of the lake’s annual amount of phosphorus came from areas that reach the lake through storm drains.

Water Quality Benefits

The benefits of the project resulted in improved treatment of urban stormwater runoff, reducing the amount of phosphorus and nitrogen reaching Glen Lake from the surrounding areas.
