The most prominent river system within California is formed by the Sacramento River and [[San Joaquin River]], which are fed mostly by snowmelt from the west slope of the Sierra Nevada, and respectively drain the north and south halves of the Central Valley. The two rivers join in the [[Sacramento–San Joaquin River Delta]], flowing into the Pacific Ocean through [[San Francisco Bay]]. Many major tributaries feed into the Sacramento–San Joaquin system, including the [[Pit River]], [[Feather River]] and [[Tuolumne River]].

The [[Klamath River|Klamath]] and [[Trinity River (California)|Trinity Rivers]] drain a large area in far northwestern California. The [[Eel River (California)|Eel River]] and [[Salinas River (California)|Salinas River]] each drain portions of the California coast, north and south of San Francisco Bay, respectively. The [[Mojave River]] is the primary watercourse in the Mojave Desert, and the [[Santa Ana River]] drains much of the [[Transverse Ranges]] as it bisects Southern California. The [[Colorado River]] forms the state's southeast border with Arizona.

Most of California's major rivers are dammed as part of two massive water projects: the [[Central Valley Project]], providing water for agriculture in the Central Valley, and the [[California State Water Project]] diverting water from Northern to Southern California. The state's coasts, rivers, and other bodies of water are regulated by the [[California Coastal Commission]].
