Oroville Dam

1

Oroville Dam is an earthfill embankment dam on the Feather River east of the city of Oroville, California, in the United States.

The United States of America, commonly referred to as the United States or America, is a federal republic composed of 50 states, a federal district, five major self-governing territories, and various possessions.

The Feather River is the principal tributary of the Sacramento River, in the Sacramento Valley of Northern California.

California is the most populous state in the United States and the third most extensive by area.

At 770 feet high, it is the tallest dam in the U.S. and serves mainly for water supply, hydroelectricity generation and flood control.

The dam impounds Lake Oroville, the second largest man-made lake in the state of California, capable of storing more than 3.5 million acre-feet, and is located in the Sierra Nevada foothills east of the Sacramento Valley.

The Sacramento Valley is the area of the Central Valley of the U.S. state of California that lies north of the Sacramento–San Joaquin River Delta and is drained by the Sacramento River.

Lake Oroville is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California.

Built by the California Department of Water Resources, Oroville Dam is one of the key features of the California State Water Project, one of two major projects passed that set up California's statewide water system.

The California State Water Project, commonly known as the SWP, is a state water management project in the U.S. state of California under the supervision of the California Department of Water Resources.

Construction was initiated in 1961, and despite numerous difficulties encountered during its construction, including multiple floods and a major train wreck on the rail line used to transport materials to the dam site, the embankment was topped out in 1967 and the entire project was ready for use in 1968.

The dam began to generate electricity after completion of the Edward Hyatt Pump-Generating Plant, then the country's largest underground power station.

An underground power station is a type of hydroelectric power station constructed by excavating the major components from rock, rather than the more common surface-based construction methods.

Since its completion in 1968, the Oroville Dam has allocated the flow of the Feather River from the Sacramento-San Joaquin Delta into the State Water Project's California Aqueduct, which provides a major supply of water for irrigation in the San Joaquin Valley as well as municipal and industrial water supplies to coastal Southern California, and has prevented large amounts of flood damage to the area – more than $1.3 billion between the years of 1987 and 1999.

The Governor Edmund G. Brown California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada Mountains and valleys of Northern and Central California to Southern California.

Southern California, often abbreviated to SoCal, is a geographic and cultural region that generally comprises California's southernmost 10 counties.

The Sacramento–San Joaquin River Delta, or California Delta, is an expansive inland river delta and estuary in Northern California.

The dam has confined fish migration up the Feather River and the controlled flow of the river as a result of the Oroville Dam has affected riparian habitat.

A riparian zone or riparian area is the interface between land and a river or stream.

Multiple aims at trying to counter the dam's impacts on anadromous fish have included the construction of a salmon/steelhead incubator on the river which began shortly after the dam was completed.

The rainbow trout is a trout and species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America.

Salmon is the common name for several species of ray-finned fish in the family Salmonidae.
