You can help prevent the spread of aquatic invasive species. Remember to CLEAN all visible aquatic plants, zebra mussels, and other prohibited invasive species from watercraft, trailers, and water related equipment. DRAIN water-related equipment (Boat, ballast tanks, portable bait containers, motor) and drain bilge, livewell, and baitwell by removing drain plugs before leaving the water access or shoreline property. Keep drain plugs out and water draining devices open while transporting watercraft. DISPOSE of unwanted bait, including minnows. leeches, 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.
Every year the state of Minnesota provides counties with funding to prevent the spread of aquatic invasive species through Aquatic Invasive Species Prevention Aid. Isanti County Commissioners then approve an annual work plan and budget. Isanti County and Isanti SWCD work in partnership to achieve the goals of the work plan.
