The San Joaquin-Sacramento River Delta is an expansive inland river delta in northern California in the United States. It is formed at the western edge of the Central Valley by the Sacramento River at its confluence with the San Joaquin River just east of where the river enters Suisun Bay (an upper arm of San Francisco Bay).

Description

The Sacramento-San Joaquin River Delta is given as an example of an inverted river delta. The fan-shaped area of the delta converges downstream, rather than diverging, as the two rivers are forced to exit the Central Valley through the Coast Range via the narrow channel known as the Carquinez Strait leading into the San Francisco Bay.

Location

The delta consists of myriad small natural and man-made channels (locally called sloughs), creating a system of isolated lowland islands and wetlands (defined by dikes or levees). The extensive system of earthen levees has allowed wide-spread farming throughout the delta, one of the most fertile agricultural areas in California. However, a burst dike can result in the flooding of a vast tract of land. On June 3, 2004, a 350 foot (110 m) section of a levee 10 mi (16 km) west of Stockton collapsed, flooding the Upper Jones Tract, a 648 acre (2.6 km²) "island".[1] The term slough (in the UK, pronounced to rhyme with cow; In the US, pronounced slew) has several meanings related to wetland or aquatic features that seem to derive from local experience. ...

The many channels throughout the delta are a popular destination for boating and fishing, and provide habitat for migratory birds. Before the building of more modern highways, automobile transportation throughout the area was accomplished by roadways along the levees and one of the most extensive systems of cable ferries in North America. Today, channels of the delta are spanned by over 50 drawbridges.

River delta - Wikipedia, the free encyclopedia (558 words)
A delta is the mouth of a river where it flows into an ocean, sea, desert or lake, building outwards (as a deltaic deposit) from sediment carried by the river and deposited as the water current is dissipated.
Deltaic deposits of larger, heavily-laden rivers are characterised by the river channel dividing into multiple streams (distributaries), these divide and come together again to form a maze of active and inactive channels.
Other rivers with notable deltas include the Ganges/Brahmaputra combination (this delta spans most of Bangladesh and West Bengal), the Niger, the Amazon, the Mississippi, the Sacramento-San Joaquin, the Rhine, the Rhône, the Danube, the Ebro, the Volga, the Lena, the Tigris-Euphrates, the Indus, the Krishna-Godavari, the Kaveri, the Ayeyarwady, and the Mekong.
