The California Department of Fish and Wildlife (CDFW)'s Invasive Mussel Control Plan Guidance document is intended to provide guidance on developing an invasive mussel control plan (Control Plan) to public and private agencies that operate a water supply system where invasive mussels have been detected. The Control Plan Template (Appendix A) is offered as a tool to assist water supply system agencies, and others, in developing a Control Plan that complies with the requirements under Fish and Game Code Section 2301 and California Code of Regulations, Title 14, Section 672 and 672.1. Use of the template, while recommended, is not required for compliance.

The guidance is available on CDFW's Quagga/Zebra Mussel webpage under the heading Invasive Mussel Control Plan Development and on the Golden Mussel webpage under the heading Additional Information, Waterbody Managers.

CDFW staff are available to assist throughout the development of a Control Plan. Please contact the CDFW Invasive Mussel Regional Scientist (PDF) based on the CDFW Region where the water supply system is located. If the water supply system spans multiple CDFW regions contact invasive@wildlife.ca.gov for assistance.
