Due to the Aquatic Invasive Species in Forest Lake, the Minnesota DNR requires all watercraft owners removing or launching their boats from or into Forest Lake with invasive species attached to carry a permit from the DNR (found at files.dnr.state.mn.us/natural_resources/invasives/ais-auth-form-boats.pdf) with them to the next location for cleaning, repairing, storing and/or launching their watercraft.
The DNR states that individual water craft owners may not transport watercraft without removing the drain plug; arrive at a lake access with a drain plug in place; transport aquatic plants, zebra mussels, or other prohibited species without permit 2015-003; launch a watercraft with prohibited species attached; release bait into the water; or place a boat lift, dock, swim raft, or associated equipment that has been removed from any water body into another water body until a minimum of 21 days have passed.
For other DNR restrictions and rules, etc. visit the DNR website or contact the DNR directly at 651-296-6157 or 888-646-6367.
Without the permit, there is the possibility of a $500 fine.
