Fresh-water mussels that can cause millions of dollars in waterway and pipeline damage have invaded Lake Piru, putting park officials at nearby Castaic Lake on heightened alert, state and county officials said Monday.
The discovery marks the first time the destructive mollusks, called quagga or zebra mussels, have been found in a Southern California water body that does not receive water from the Colorado River.
Lake Piru Recreation Area staff reported the discovery of potential quagga mussels to Fish and Wildlife officials on Dec. 18.
