This will be a virtual presentation and is open to the public to attend and learn more about Crow Wing County’s AIS prevention plan for 2021. Topics to be highlighted include watercraft inspections, decontaminations, education and awareness, milfoil treatments and early AIS detection. Visit the county’s website at www.crowwing.us/ais for more information about how to join the virtual online presentation.

Crow Wing County has been allocated $440,901 by the State Legislature to assist in the prevention of the spread of AIS within County lakes and rivers in 2021. The AIS prevention plan proposes to accomplish this through several approaches, including:

Watercraft inspections -- In the past, Crow Wing County partnered with the University of Minnesota-Aquatic Invasive Species Research Center and the United States Department of Agriculture-Forest Service to develop an optimized model for locating DNR trained watercraft inspectors on Crow Wing’s County’s public watercraft access landings. For the first time in 2020, Minnesota-Aquatic Invasive Species Research Center developed an online dashboard of this model called AIS Explorer for local government AIS managers and staff. This online dashboard uses existing infestation information, water connectivity risk modeling, and over 1.6 million boater movement survey results to forecast the introduction risk of four priority AIS (zebra mussels, Eurasian watermilfoil, starry stonewort, and spiny waterflea) at individual lakes throughout the County. In total, 17,040 watercraft inspection hours are proposed to be allocated on 42 landings in 2021.


Decontamination units -- The county plans to operate the AIS decontamination station located at the Crosslake Joint Highway Maintenance Facility that will be open 9 a.m.-5 p.m. Thursday through Sunday. The county also plans to operate a mobile decontamination station located at five public landings including Edward, Lower Hay, Lower Cullen, Pelican-Halverson Bay, and Upper South Long lakes that will be open Friday through Sunday. Both decontamination stations will be open from Memorial Day weekend through the end of September, free of charge. Call the Crow Wing County Decon Hotline at 218-824-1055 for more details during the summer season. Watercraft decontamination consists of a very hot water rinse to kill zebra mussels and, if needed, a high pressure spray to remove AIS from boats, motors, trailers, and personal gear.

Treatment of Eurasian water milfoil -- Crow Wing County has 10 lakes that are infested with milfoil that also have a public access. As in previous years, funds will be allocated for chemical or biological treatment of milfoil in these lakes.

Education and awareness -- Since 2014, Crow Wing County has allocated approximately $40,000 directly to lake associations to conduct an education outreach campaign to the general public. Over 30 lakes have participated. In 2021, the county plans to again offer this program. The county proposes funding 18 lakes for lake association public awareness campaigns. In addition, other proposals are education and awareness initiatives including partnering with bait shops, printed media, and other targeted advertising. Since 2014, approximately $184,000 has been allocated to covering the costs of AIS related education and awareness programs.

Early AIS Detection -- The county plans to continue to work with area lake associations and an environmental lab to conduct Zebra Mussel veliger and Spiny waterflea testing in 2021.

In 2020, Crow Wing County allocated 17,040 watercraft inspection hours on 42 public access landings across the County. Lake Associations added an additional 5,000 hours of expanded coverage requests that the County scheduled beyond its County Board approved hours..

No newly infested Zebra Mussel lakes were identified in Crow Wing County in 2020. This shows that the optimized model Crow Wing County used by the Minnesota-Aquatic Invasive Species Research Center and USDA Forest Service has been successful. Information about Crow Wing County AIS prevention efforts, including interactive maps to search for the statues of area lakes can be found on the web at www.crowwing.us/ais .

Residents are encouraged to contact the Land Services Office at 218-824-1010 or landservices@crowwing.us to discuss AIS or other land use related activities.
