"The Department of Water Resources (DWR) is responsible for managing and protecting California’s water resources. DWR works with other agencies to benefit the State’s people and to protect, restore, and enhance the natural and human environments."
Established in 1956 by the California State Legislature, DWR protects, conserves, develops, and manages much of California's water supply. This includes the State Water Project (SWP), the nation’s largest state-built water conveyance program.
The SWP supplies water to an estimated 25 million Californians and 750,000 acres of farmland. It spans more than 600 miles from Northern California to Southern California and includes 34 storage facilities, 20 pumping plants, 5 hydroelectric power plants, 4 pumping-generating plants, and approximately 700 miles of canals, tunnels, and pipelines. In addition to supplying high-quality water for California’s cities, industries, and farms, the SWP also provides flood control, hydroelectric power generation, recreational opportunities, and ecosystem enhancements to protect fish and wildlife habitat.
Sustainability is our priority. We strive to meet the water needs of today and those of the future, while protecting and enhancing the environment. This balancing act is an enduring challenge and commitment. We work with many federal, State, and local partners to protect and restore the critically important Sacramento-San Joaquin Delta in a way that also ensures long-term water supply reliability for the state.
DWR's major responsibilities include:
- Overseeing the statewide process of developing and updating the California Water Plan (Bulletin 160 series)
- Planning, designing, constructing, operating, and maintaining the SWP
- Protecting and restoring the Sacramento-San Joaquin Delta
- Regulating dams, providing flood protection, and assisting in emergency management
- Working to preserve the natural environment and wildlife
- Educating the public about the importance of water, water conservation, and water safety
- Providing grants and technical assistance to service local water needs
- Collecting, analyzing, and reporting data in support of our mission to manage and protect California’s water resources
We believe our employees and others have a right to a safe work environment and that all incidents are preventable. Safety is one of our core values and we are committed to our employees, contractors, cooperating agencies, and the visiting public to preventing occupational injuries and illnesses.
The Department will strive to continually improve safety through engagement from all organizational levels and continue to be a leader in employee safety. Active employee participation in the Department safety process is fundamental to improving workplace safety, key to successful implementation of the Department’s Safety System, and strongly encouraged.
