ABOUT NORTHWEST ANDERSON LAKE
Northwest (NW) Anderson Lake is one of three connected lakes bridging the border between Bloomington and Eden Prairie.
The District’s water quality improvement projects improved the lake’s water quality from prior years. Previously, NW Anderson Lake had too much phosphorous due, in part, to curly-leaf pondweed, an invasive aquatic plant. Phosphorous fuels algae growth, and too much can lead to unwanted algae blooms. Reduced curly-leaf pondweed levels have helped the lake meet state water quality standards for phosphorous. Water clarity also increased as a result of the District’s water quality improvement projects.

The Nine Mile Creek Watershed District conducted a lake drawdown to improve the health of NW Anderson Lake. The project goals were to reduce the amount of curly-leaf pondweed, an invasive aquatic plant, and control phosphorus levels in the lake. The NW Anderson Lake drawdown occurred in the fall of 2008 until the spring of 2009. Follow-up herbicide treatments occurred from 2010-2013. Monitoring data from 2018 indicate that the water quality improvement projects have successfully controlled curly-leaf pondweed and improved water quality. Monitoring will continue to track the success of the projects.

NW Anderson Lake does not have many recreation opportunities. There are however, 2.1 miles of paved and turf trails at the Three Rivers Park District Anderson Lakes Park Reserve.
The Minnesota Department of Natural Resources may have additional information on the lake (including fishing regulations; location; water access sites; lake maps; lake reports on stocking, ice in/out and water quality; fish consumption; and aquatic plant surveys) if so, that information can be found here:
