Phosphorus loading has caused some blue-green algae blooms, but algal toxins were below public health advisory levels. Latest aquatic plant surveys have shown Lone Lake is healthy with up to 18 different species present. Overall, Glen lake is healthy with no water impairments listed.

Past Projects

Glen Lake, Minnetonka

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. conditions. These improvements were part of the larger Minnetonka Lakes Water Quality Improvement Project.

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.
