In January 2007, in response to the discovery of quagga mussels (a closely related species to the zebra mussel) in the Colorado River system (Lakes Mead, Mohave, and Havasu), California implemented a statewide survey of all California waterways (lakes, reservoirs, rivers, and water diversions) to delineate the extent of the population. The interagency Quagga Mussel Incident Response Team trained survey crews in quagga and zebra mussel surveying techniques. Training covered mussel identification, sampling techniques, survey protocol, and data reporting requirements. Below are the links to the protocols, data sheets and training presentations that were developed. The California Department of Fish and Game now coordinate all quagga/zebra mussel training for the State.
