When boating or fishing on Minnesota lakes, protect our lake from invasive aquatic plants (milfoil) and animals (zebra mussels) by performing the the steps listed below each time to enter or leave the lake.

Clean-In Clean-Out is a DNR program designed to educate boaters and anglers about the transport and transfer of invasive plants and animals from lake to lake.

"We are here to help and inform you about Aquatic Invasive Species".
