Minnesota law requires docks and boat lifts to be out of the water for at least 21 days before putting them in another body of water.
When removing boats, docks, lifts, or other water-related equipment from lakes and rivers, carefully inspect everything to make sure there are no aquatic invasive species (AIS) such as zebra mussels, Eurasian watermilfoil, or New Zealand mudsnails attached.
Look on the posts, wheels, and underwater support bars of docks and lifts, as well as any parts of boats, pontoons, and rafts that may have been submerged in water for an extended period. In newly infested waters, adult zebra mussels may not be abundant and you might notice only a few mussels on your equipment.
If you think you have discovered an invasive species that has not already been confirmed in your lake, contact your area DNR aquatic invasive species specialist.
