Aquatic Invasive Species (AIS)

Aquatic invasive species (AIS) are non-native plants, animals, or pathogens that live primarily in water and thrive in their new environment, often out-competing native species. Well known AIS include: zebra mussels, curlyleaf pondweed, Eurasion watermilfoil, spiny waterflea, sea lamprey, and Asian carp. AIS management has quickly become one of the County's biggest challenges. Although the scenario varies by lake and by species, it is clear that the easiest and most cost effective method is prevention.

When Crow Wing County was identifying the priorities for the 2013 - 2023 Water Plan, a survey was sent to all riparian landowners in the County as well as to various stakeholder groups and to the general public (via a press release and participation at the County Fair). The results of that survey indicated that Aquatic Invasive Species (AIS) was the top surface water priority. As the survey indicates, Crow Wing County has seen an ever-increasing demand from citizens and lake associations to become an active participant in the fight against AIS.

The County's stated goal with respect to AIS in the 2013-2023 Water Plan is: To provide leadership in the fight against Aquatic Invasive Species by developing proactive solutions aimed at educating and empowering local citizens.

Under this goal are four primary objectives:

1. Lake Association Coordination
2. Watercraft Inspection
3. Lake Improvement District (LID) Management
4. Education and Outreach

Decontamination stations are available to boaters free of charge, with priority given to boaters who have been referred for decontamination by watercraft inspectors or law enforcement present on area landings.
