California Aqueduct
Overview

Have you ever wondered where the water you drink and use comes from? To reach many of us, water must travel long distances through complex delivery systems such as the California State Water Project. The SWP is the nation's largest state-built water and power development and conveyance system.

Planned, designed, constructed and now operated and maintained by the California Department of Water Resources, this unique facility provides water supplies for 23 million Californians and 755,000 acres of irrigated farmland.

Please use the links on the upper right to learn more about water in California.
