Document Description
Quagga and zebra mussels are an invasive mussel that, if introduced into a waterway, can devastate the natural environment, clog water and flood protection infrastructure, and cost millions of dollars in maintenance. Mussels are transported between waterways by watercraft, primarily recreational boats. The proposed project would provide watercraft inspection services to prevent quagga and zebra mussel infestation into Lake Mendocino. The proposed project would also provide inspection training to help develop year-round inspections.
