California’s water system is one of the most complex and important in the world. It delivers water to millions of people across the state and supports ecosystems that are vital to California’s environmental health. At the heart of this system is the Sacramento-San Joaquin Delta, a region where two rivers merge and water is pumped to communities across the state via California’s State Water Project (SWP) and the federally run Central Valley Project (CVP).
These systems don’t just serve people. They support native fish species – some whose survival depends on how, when and where water moves through the Delta.
