This is a list of rivers in the U.S. state of California, grouped by region. Major lakes and reservoirs, if applicable, are indicated in italics.
Rivers and streams between the Oregon border and Humboldt Bay that empty into the Pacific Ocean (arranged north to south; tributaries with those entering nearest the sea first). Bold indicates rivers with more detailed lists in following sections.
Primary streams entering Humboldt Bay are listed north to south beginning north of the entrance to the bay and continuing in a clockwise direction. Tributaries entering nearest the bay are listed first. [1] [2]
For additional detail on Humboldt Bay streams, see Humboldt Bay: Bay tributaries and sloughs.
Rivers and streams between Humboldt Bay and the Golden Gate that empty into the Pacific Ocean (arranged north to south; tributaries with those entering nearest the sea first):
For details of the Sonoma and Marin coasts, see List of watercourses in the San Francisco Bay Area.
Streams that empty into San Francisco Bay or its tributary bays (arranged clockwise, starting at the north side of the Golden Gate; tributaries are listed from those entering nearest the bays to farthest). The Central Valley watershed feeding into Suisun Bay via the Sacramento–San Joaquin Delta is excluded; see the following section for the Sacramento and San Joaquin river systems.

The Sacramento and San Joaquin River systems drain the western slope of the Sierra Nevada and most of the Central Valley, forming the Sacramento–San Joaquin River Delta before emptying into Suisun Bay; together, they are the largest river system in California.
Note: In the Delta the Mokelumne River divides into two short branches, also called the "North Fork" and "South Fork", which recombine before reaching the San Joaquin River.
Usually an endorheic basin, waters in this region all eventually would reach Tulare Lake. This region would overflow into the San Joaquin River during flood years when Tulare Lake overflowed. Streams are listed clockwise around the Tulare Basin, starting at the Kings River:
Rivers that empty into the Pacific Ocean between the Golden Gate and Point Arguello, arranged in order from north to south.
For details of the San Mateo coast, see List of watercourses in the San Francisco Bay Area.
Rivers that empty into the Pacific Ocean southeast of Point Arguello, arranged from north to south:
Tributaries entering San Diego Bay are arranged from North to South:
Rivers that empty into the Gulf of California:
The Carrizo Plain is a large enclosed valley near the Central Coast which drains into Soda Lake.
Rivers that empty into the Salton Sea:
Rivers in the Great Basin, arranged roughly north to south:
Rivers draining into saline and endorheic Mono Lake in eastern California, from north and proceeding counterclockwise:
Streams terminating in the Badwater Basin in Death Valley National Park.
Streams terminating in various dry lakes in the Antelope Valley and Fremont Valley (Koehn Lake, Rosamond Lake, Rogers Dry Lake and others), draining from the southeastern Tehachapi Mountains and northern San Gabriel Mountains, listed counterclockwise starting from north:
The Kings River, is a 132.9-mile (213.9 km) river draining the Sierra Nevada mountain range in central California in the United States. Its headwaters originate along the Sierra Crest in and around Kings Canyon National Park and form the eponymous Kings Canyon, one of the deepest river gorges in North America. The river is impounded in Pine Flat Lake before flowing into the San Joaquin Valley southeast of Fresno. With its upper and middle course in Fresno County, the Kings River diverges into multiple branches in Kings County, with some water flowing south to the old Tulare Lake bed and the rest flowing north to the San Joaquin River. However, most of the water is consumed for irrigation well upstream of either point.
The Kern River, previously Río de San Felipe, later La Porciúncula, is an Endangered, Wild and Scenic river in the U.S. state of California, approximately 165 miles (270 km) long. It drains an area of the southern Sierra Nevada mountains northeast of Bakersfield. Fed by snowmelt near Mount Whitney, the river passes through scenic canyons in the mountains and is a popular destination for whitewater rafting and kayaking. It is the southernmost major river system in the Sierra Nevada, and is the only major river in the Sierra that drains in a southerly direction.
The Mono are a Native American people who traditionally live in the central Sierra Nevada, the Eastern Sierra, the Mono Basin, and adjacent areas of the Great Basin. They are often grouped under the historical label "Paiute" together with the Northern Paiute and Southern Paiute – but these three groups, although related within the Numic group of Uto-Aztecan languages, do not form a single, unique, unified group of Great Basin tribes.
The San Jacinto River is a 42-mile-long (68 km) river in Riverside County, California. The river's headwaters are in Santa Rosa and San Jacinto Mountains National Monument. The lower portion of the 765-square-mile (1,980 km2) watershed is urban and agricultural land. As a partially endorheic watershed that is contiguous with other Great Basin watersheds, the western side of the San Jacinto Basin is a portion of the Great Basin Divide.
The Fresno River is a river in Central California and a major tributary of the San Joaquin River. It runs approximately 83 miles (134 km) from the Sierra Nevada Range to the San Joaquin River if measured from the source of Rainier Creek, near Raymond Mountain in Yosemite National Park. Although called the 'Fresno' River, it is one of the largest and longest river systems in Madera County.
The Chowchilla River is a river in central California, United States and a minor tributary of the San Joaquin River. It flows for 54.2 miles (87.2 km) from the western side of the Sierra Nevada Range to the San Joaquin River system in the San Joaquin Valley.
Tujunga Wash is a 13-mile-long (20.9 km) stream in Los Angeles County, California. It is a tributary of the Los Angeles River, providing about a fifth of its flow, and drains about 225 square miles (580 km2). It is called a wash because it is usually dry, especially the lower reaches, only carrying significant flows during and after storms, which usually only occur between November and April. The name of the wash derives from a Tongva village name.
The Rio Chama, a major tributary river of the Rio Grande, is located in the U.S. states of Colorado and New Mexico. The river is about 130 miles (210 km) long altogether. From its source to El Vado Dam its length is about 50 miles (80 km), from El Vado Dam to Abiquiu Dam is about 51 miles (82 km), and from Abiquiu Dam to its confluence with the Rio Grande is about 34 miles (55 km).
The Los Gatos Creek runs 24 miles (39 km) in California through Santa Clara Valley Water District's Guadalupe Watershed from the Santa Cruz Mountains northward through the Santa Clara Valley until its confluence with the Guadalupe River in downtown San Jose. The Guadalupe River then continues onward into San Francisco Bay.
San Diego Creek is a 16-mile (26 km) urban waterway flowing into Upper Newport Bay in Orange County, California in the United States. Its watershed covers 112.2 square miles (291 km2) in parts of eight cities, including Irvine, Tustin, and Costa Mesa. From its headwaters in Laguna Woods the creek flows northwest to its confluence with Peters Canyon Wash, where it turns abruptly southwest towards the bay. Most of the creek has been converted to a concrete flood control channel, but it also provides important aquatic and riparian habitat along its course and its tidal estuary.
Cottonwood Creek is a major stream and tributary of the Sacramento River in Northern California. About 68 miles (109 km) long measured to its uppermost tributaries, the creek drains a large rural area bounded by the crest of the Coast Ranges, traversing the northwestern Sacramento Valley before emptying into the Sacramento River near the town of Cottonwood. It defines the boundary of Shasta and Tehama counties for its entire length. Because Cottonwood Creek is the largest undammed tributary of the Sacramento River, it is known for its Chinook salmon and steelhead runs.
