Carver County Aquatic Invasive Species (AIS) Program

The program's purpose is to reduce spread of Aquatic Invasive Species (AIS). AIS are species not native to Minnesota's aquatic ecosystem and are able to reproduce easily and rapidly. AIS have significant ecological, environmental, recreational and public health impacts on our lakes and rivers. In 2014, the State of Minnesota began providing funds to each County with public water accesses to help prevent spread of AIS on a local level. Carver County receives approximately $132,000 annually to assist AIS efforts.  With these finances, the WMO has developed a program to combat AIS through three areas: Education, Monitoring and Inspections.

Help Prevent the Spread

CLEAN plants, mud, zebra mussels and other animals/fish from boats, watercrafts, trailers, and recreation equipment before leaving any water access or shoreland. Rinse equipment with high-pressure, hot water.

DRAIN equipment including boat, ballast tanks, portable bait containers, motor, and swimming equipment. Also drain bilge, livewell and baitwell by removing drain plugs before leaving a water access or shoreline property. Keep drain plugs out and water-draining devices open while transporting watercraft.

DRY everything that came in contact with water for at least five days to be sure you have destroyed eggs or young zebra mussels. Store your boat on land if possible.

DISPOSE of unwanted bait, including minnows, leeches, and worms in the trash. It is illegal to release live bait into a waterbody or release aquatic animals from one waterbody to another. If you want to keep your live bait, you must refill the bait container with bottled or tap water.
