California water

California water has three sources:[1]

* Central Valley Project
* State Water Project based mostly on northern sources such as the Sierra Nevada mountains
* the Colorado River and the federal system based on that
* local reservoirs and streams
* groundwater such as wells

The state-based Sierra Nevada system supplies 30% of Southern California's water supply. The Colorado River supplies a substantial but smaller percentage, based on a federal system.

California takes an unfair priority over Arizona for water from the Colorado River, due to favoritism suspected of Herbert Hoover when he negotiated the original deal a century ago.
