Bloomington & Eden Prairie

ABOUT ANDERSON LAKES

The Anderson Lakes are located in Eden Prairie and Bloomington. These three shallow lakes have had issues with invasive aquatic plants in the past, which the District has sought to address. There are hiking trails in the Anderson Lakes Park Reserve that offer an excellent place to look for wildlife in the heart of an urban area.

Water Quality

Southeast Anderson Lake

Northwest Anderson Lake

2014 monitoring data indicated that the water quality in the lake was excellent. All parameters for the Minnesota State Water Quality Standards for shallow lakes were met. The District water quality improvement projects substantially improved the lake’s water quality from prior years.

Southwest Anderson Lake

2013 monitoring data indicated that the lake’s water quality was excellent. All parameters for the Minnesota State Water Quality Standards for shallow lakes were met. The District water quality improvement projects substantially improved the lake’s water quality from prior years.

Southeast Anderson Lake

In 2013, the water quality was excellent; however, in 2014 monitoring data indicated that the water quality in the lake was poor. The Minnesota State Water Quality Standards for shallow lakes are not being met. The District’s water quality improvement project reduced curly-leaf pondweed to 0% (not observed) in 2014. Now that the curly-leaf pondweed is controlled, further steps will need to be examined to address water quality.

Past Projects

Northwest and Southwest Anderson Lakes

In the fall of 2008, the District initiated a project to drawdown Northwest and Southwest Anderson Lakes to address an invasive aquatic plant called curly-leaf pondweed. The intent of the project was to expose the lake bottom to freeze and kill the turions (seed) of the curly-leaf pondweed plants. Learn More (Link to past projects page)

Southeast Anderson Lake

A project was ordered in 2008 to address curly-leaf pondweed internal phosphorus loading through treatment with Endothall for 4-5 successive years. Treatments started in 2008 and were continued through 2013.
