In 1955, severe flooding killed 64 people and caused $200 million in property damage in Northern and Central California. In response, Governor Goodwin J. Knight called a special session of the Legislature to create the Department of Water Resources (DWR). The new department was tasked with planning, designing, constructing, and overseeing the nation’s largest state-built, multi-benefit water conveyance system – the State Water Project (SWP). DWR also took over the duties of a reconstituted State Water Resources Board, which was renamed the State Water Board and later changed to the California Water Commission.

Since our inception, we've created and maintained a massive system of dams, reservoirs, canals, pumping and power plants, and more that remain the backbone of California’s water supply system. We continue to develop strategic goals and near- and long-term actions to conserve, manage, develop, and sustain our water resources and management systems.
