Annual meeting in August

Outlet and Lake water level updates

The beaver dam at the Shanaska Creek outlet this spring has been removed, and the lake was moving back to the DNR approved level. But recent attempts to capture and remove the beaver have not been successful. There is a new dam built about 10yards south of the outlet structure. This will be discussed as to how to proceed at a future meeting. If you have input, please contact the Board.
