    Golden mussels in California: What Santa Clara County needs to know

    California’s water infrastructure is facing a new threat—one that’s tiny, invasive, and alarmingly fast-spreading. Golden mussels, native to Asia, were first detected in the Delta in 2024 and have spread to several California waterbodies hydrologically connected to the Sacramento-San Joaquin Delta, including San Luis Reservoir. These invaders pose a serious risk to water delivery systems across the state, including those serving Santa Clara County.

    Statement From Valley Water Board Chair Tony Estremera regarding César Chávez Day

    The annual César Chávez Day has long represented more than the life of one person. It is a moment to recognize the broader fight for dignity, fair treatment, and the rights of farmworkers and working people whose labor sustains our communities.

Content

Valley Water imports about half of the water used in Santa Clara County via contracts with the State Water Project and the federal Central Valley Project (CVP).  Every five years, CVP contractors are required by the Bureau of Reclamation (Reclamation) to prepare a Water Management Plan (WMP) to meet requirements of the Central Valley Project Improvement Act (CVPIA). Valley Water as a CVP contractor is subject to this requirement and has completed its 2022 WMP. Valley Water’s 2022 WMP documents its service area characteristics, operations and management of its system, inventory of current water resources, and water conservation and demand management efforts during the past five years.

To ensure compliance with the plan, annual reports on the implementation of Urban and Agricultural Best Management Practices (BMP's) are also submitted to Reclamation in April every year. The reports show that Valley Water continues to implement applicable BMPs to promote water conservation with strong public outreach and school education programs, tracking and managing water loss, optimizing conjunctive use of surface and groundwater, and encouraging the use of recycled water.
