Watershed Management Plan

The Middle St. Croix Watershed Management Organization works with residents, organizations, and its member communities of Afton, Bayport, Baytown Township, Lakeland Shores, Lakeland, Lake St. Croix Beach, Oak Park Heights, St. Mary’s Point, Stillwater, and West Lakeland Township to collectively protect and manage the quality of water resources in an efficient and effective manner.

Watershed organizations must update their Watershed Management Plan once every ten years. The 2015-2025 MSCWMO Watershed Management Plan was adopted on September 23, 2015. 

If you have questions or would like more information, please contact Matt Oldenburg-Downing, MSCWMO Administrator at MOldenburg-Downing@mnwcd.org or 651-796-2227.
