    Prevention Grant

    Quagga and Zebra mussels pose a serious threat to our waters and fisheries. The spread of these mussels threatens recreational boating and fishing, aquatic ecosystems and fisheries, water delivery systems, hydroelectric facilities, agriculture and the environment in general. As a means to stop the spread of these harmful invasive mussels, California is asking boaters to clean, drain and dry their boats!

    Boaters should be prepared for inspections throughout the state designed to help ensure California's water bodies remain mussel-free. Properly cleaning and drying can help protect boats and help boaters avoid quarantines or being turned away from a water destination. In addition to being sure to clean, drain and dry watercraft, the Division of Boating and Waterways urges boaters to plan for possible launch restrictions and inspections by calling water bodies before leaving home. Programs and requirements vary and can change rapidly.
