Aquatic invasive species (AIS), like zebra mussels and Eurasian watermilfoil, can displace native plants and animals, disrupt fishing, boating and swimming activities, and are costly to manage. People unintentionally spread AIS by moving boats, gear, and equipment from one waterbody to another. Once they establish themselves in a new lake or river, they are difficult to remove.
Watercraft inspections serve as our most effective line of defense by "stopping aquatic hitchhikers" before they enter the water. By combining a watercraft inspection of the with simple education on the "Clean, Drain, Dry" method, inspectors can stop the spread at the source and ensure our waters remain healthy.
