Aquatic Invasive Species

Aquatic invasive species (AIS) are non-native plants, animals, and pathogens that live primarily in water. These species thrive here in their new environment and cause economic loss, environmental damage, and harm to human health.

Infested waters in Mille Lacs County include:

  • Lake Mille Lacs

Help Prevent the Spread

  • Clean all visible aquatic plants, zebra mussels, and other prohibited invasive species from watercraft, trailers, and water-related equipment before leaving any water access or shoreland. 
  • Drain water-related equipment (boat, ballast tanks, portable bait containers, motor) and 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 (5) days.
  • Dispose of unwanted bait, including minnows, leeches, and worms, in the trash. It is illegal to release bait into a waterbody or release aquatic animals from one waterbody to another. If you want to keep your bait, you must refill the bait container with bottled or tap water.
