The heart of California’s water system and the largest estuary on the West Coast—the Sacramento-San Joaquin Delta—is highly vulnerable. Environmental concerns are mounting. Water supplies are at risk.
The U.S. Geological Survey has warned of a 63 percent probability that a 6.7 magnitude or larger earthquake will hit in the next 30 years. An earthquake of that size has the power to not only devastate local communities, but wipe out a significant portion of the state’s water supply for more than a year.
Delta Disrupted is a public education and outreach program aimed at raising awareness of the risks we face and the solutions before us.
State Water Project
The State Water Project is the nation's largest state-built water and power development and delivery system. Stretching from Northern California through the Bay Area, the Central Valley and into Southern California, it is a multi-faceted system that includes reservoirs, lakes, storage tanks, canals, tunnels, pipelines and pumping and power plants. Together, these elements enable the state to capture, store, and convey water to 27 public water agencies. Through the State Water Project, State Water Contractors member agencies deliver water to more than 26 million residents, businesses and farms up and down California.
Bay Delta Conservation Plan
The Bay Delta Conservation Plan is the path towards a secure water supply for California and a healthy Delta ecosystem. This comprehensive effort is an innovative, science-based solution to California’s water supply challenges and the Delta’s environmental struggles. Just as our predecessors advanced crucial infrastructure projects to prepare California for the last 50 years, our members are working with state and federal agencies, environmental organizations and other water agencies to secure water supplies for the decades to come.
