East Bay Regional Park District manages recreation at Contra Costa Water District’s Contra Loma Reservoir. As part of an invasive mussel prevention grant program from the California State Parks Division of Boating and Waterways, the East Bay Regional Park District is conducting a short survey on quagga and zebra mussel prevention in Regional Park lakes and reservoirs. Invasive Dreissenid Mussels, commonly known as quagga and zebra mussels, can quickly contaminate waterways and rapidly spread via watercraft, trailer, or equipment from infected waters. Please help keep invasive mussels out of our waters, and participate in this survey.
