California State Parks to Implement New Boat Launching Requirements for Golden Mussel Prevention at Folsom Lake and Lake Clementine
FOLSOM – Effective Monday, April 14, 2025, the U.S. Bureau of Reclamation will require all trailered or motorized vessels launching at Folsom Lake and Lake Clementine to participate in a vessel inspection/quarantine program to help prevent the spread of golden mussels. This highly invasive aquatic species was recently identified in the Sacramento-San Joaquin Delta, the first known occurrence of golden mussels in North America. Golden mussels pose a significant threat to the ecological health of all waters of the state, its water conveyance systems, infrastructure, and water quality.
