Preventing the Spread of Invasive Species

Carboat_guideline7Aquatic nuisance species, such as the New Zealand mud snail and Eurasian milfoil, pose a serious threat to the biological diversity and economy of Washington. Many non-native invasive species spread rapidly in areas that do not have their natural predators. These organisms are spread unintentionally as hitchhikers on boats, trailers, and gear. It is against Washington state law to transport any aquatic nuisance species. Be sure to thoroughly inspect and rinse your boat (including jet skis and kayaks), fishing equipment, and wading boots.
