Lake User Survey

Thank you to everyone who took the lake user survey. The survey provided community feedback to Nine Mile Creek Watershed District staff, engineers, and the board of managers, along with the City of Eden Prairie. The feedback helped assist in the evaluation of management strategies designed to improve the health of Birch Island Lake. The survey targeted 160 addresses in the Birch Island Lake subwatershed and was active December 19 – January 31, 2023. The survey received 16 responses.
