Since golden mussels were recently identified in the Sacramento-San Joaquin Delta, officials introduced new rules for boaters at some waterways in parts of Northern California and the Bay Area. … Federal and California state officials announced Monday a set of new inspection and quarantine requirements for the launch of boats at Folsom Lake and Lake Clementine. Those will take effect starting April 14. This comes after other new restrictions have been put in place at Rancho Seco Lake, Woodward Reservoir and Lake Berryessa, among other water bodies. The state maintains a list of where watercraft inspections are required for certain vessels to combat the spread of golden mussels, zebra mussels and quagga mussels. Because the list may not have the latest information, boaters are urged to contact the agency that manages the water body they plan to visit. See more in the map below.
