Golden mussel, an invasive, non-native freshwater bivalve, was recently discovered in the Port of Stockton by California Department of Water Resources staff while conducting routine operations. Suspected golden mussels have also been identified at O’Neill Forebay in Merced County and are currently undergoing genetic testing for confirmation.

Preventing harmful impacts of non-native plants and animals protects the biodiversity of California — home to more species than any other state in the union.

CDFW was informed by the Tahoe Regional Planning Agency (TRPA) that divers monitoring for aquatic invasive species in Lake Tahoe detected invasive New Zealand mudsnails (Potamopyrgus antipodarum) in areas off the South Shore of Lake Tahoe. New Zealand mudsnail samples were subsequently positively identified by experts within CDFW and an outside genetics lab. This is the first time the species has been detected in Lake Tahoe.

As another California boating season winds down, boaters are being asked to remember the importance of cleaning, draining and drying their watercraft to combat the spread of invasive quagga and zebra mussels.

CDFW is pleased to announce Lieutenant Specialist Trevor Pell as the 2022 Wildlife Officer of the Year.
