State officials are confirming the discovery of an infestation of non-native mussels in a Ventura County lake.
The State Department of Fish And Wildlife has tentatively identified mussels found at Lake Piru as Quagga mussels.
They are a type of mussel native to Eurasia, and can multiply rapidly.
The quagga mussels can clog water pipes and other water infrastructure, and compete for food with native species.
They attach themselves to boats, so they can be spread from one body of water, to another via infected boat hulls, engines, or bilges.
Lake Piru staff members are working to try to determine the extent of the infestation.
They’re requiring all boaters to clean, dry, and inspect their boats before leaving the lake.
State officials say this is the first time the mussels have been found in a body of water in Southern California which isn’t linked to the Colorado River.
