Quagga and Zebra mussels are highly destructive invasive mollusks which have established themselves in many locations in North America, including some in California. These data summarize the locations of these mussels within California by waterbody using data collected by the United States Geological Survey from CDFW and other state and local agencies.
Quagga (Dreissena rostriformis bugensis) and Zebra (Dreissena polymorpha) mussels are highly invasive and easily transported from one waterybody to another. California has an extensive program designed to prevent the spread of these mussels. This program is coordinated by the California Department of Fish and Wildlife (CDFW) Invasive Species Program, within the Habitat Conservation Planning Branch. This data set summarizes the locations of Quagga and Zebra mussel findings within California waterbodies, using data from the U.S. Geological Surveys NAS (Nonindigenous Aquatic Species) database.
