Eden Prairie & Bloomington
ABOUT
The District is conducting a water quality study on the Anderson chain of lakes which includes Southwest Anderson Lake, Southeast Anderson Lake, and Northwest Anderson Lake.
Project Description
In 2005, the watershed district completed a water quality study for the Anderson Lakes. That water quality study identified curly-leaf pondweed, an aquatic invasive species, as a threat to lake health. In response to the study, the district completed the following water quality improvement projects:
- 2008 Southwest and Northwest Anderson lakes drawdown
- 2012 Southwest Anderson Lake alum treatment
- 2008-2013 Southeast Anderson Lake herbicide treatments
Because it’s been over 10 years since the district completed a management activity on these lakes, the district’s board of managers have approved a scope of work to assess the status of current lake health and identify protection and management actions as needed. This study will look at:
- Historical in-lake data i.e. lake nutrient levels, aquatic plant populations, fisheries, and lake levels
- An analysis of upland habitat and land-use
- Reevaluation of lake goals and management techniques
Outreach
Public Meeting # 2 TBD
Past Community Meetings
- On August 19th, 2025, the watershed district will held a informal public meeting, for Southeast, Southwest and Northwest Anderson Lakes. Come and learn about the current health of Anderson Lakes, upcoming plans, how the implementation process will move forward, and provide input.
Anderson Lakes Chain Public Meeting #1 August 19, 2025 presentation
- On September 17th, 2024, the watershed district held a community meeting with the surrounding lakeshore owners on Southeast Anderson Lake. At the meeting, staff from the watershed district gave a short presentation on lake health and past projects. There was also an opportunity for the attendees to voice concerns they have about the lake which helped inform the areas of focus within the current water quality study’s scope.
