Project Description

The District is undertaking a lake water quality study on Birch Island Lake to identify potential water quality improvement projects to help improve the overall health of the lake.


Lake User Survey

The lake user survey is meant to provide community feedback to watershed district staff, engineers, and the board of managers, along with the City of Eden Prairie to assist in the evaluation of management strategies designed to improve the health of Birch Island Lake.

The survey was available December 19th, 2022-January 31st, 2023. An postcard with an online survey link was mailed to 160 addresses in the subwatershed of Birch Island Lake on December 20, 2022. Stakeholders that attended the community meeting on January 9, 2023, were also encouraged to take the survey and were emailed the survey link following the meeting. The survey link was also available on this webpage . Sixteen survey responses were received.
