Wisconsin and Utah Implement Diverse Strategies to Combat Aquatic Invasive Species
Northern Wisconsin and Utah are employing different strategies to combat aquatic invasive species (AIS). In Wisconsin, the Vilas County boat decontamination program, a partnership with the University of Wisconsin-Oshkosh, uses mobile heated pressure washers to decontaminate boats, primarily targeting the spiny water flea. Josh Stirn, part of the program, travels to four lakes known to have the invasive species, offering voluntary decontamination. In 2025, approximately 13% of boats were decontaminated using this mobile unit. Meanwhile, Utah, battling invasives like quagga mussels and Eurasian water milfoil, has adopted large 'dip tanks' for watercraft decontamination. These tanks, developed by Clean Wake LLC, allow boats to be lowered into heated water, flushing out invasive organisms from internal systems. Utah currently has five dip tanks with plans for two more, and their biological testing shows 100% mortality of invasives. Both states have laws requiring some form of decontamination or inspection for ...
