Stop Aquatic Hitchhikers
Aquatic nuisance species pose a serious threat to the recreational and natural resources of Lake Tahoe.  Aquatic weeds and invasive mussels spread by hitchhiking on boats, trailers and equipment.  Quagga mussels have been found in CA and NV.  Don't let them come to Lake Tahoe.  Stop the spread!  Clean. Drain. Dry.  Learn more!
