Lake Oroville

Lake Oroville, is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated 5 miles (8.0 km) northeast of the city of Oroville, within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada.

At over 3,500,000 acre feet (4.3 km³), it is the second-largest reservoir in California, after Shasta Lake. The lake is fed by the North Fork, Middle Fork, West Branch and South Forks of the Feather River.

The lake has an unmarked 9,000 ft (2,700 m) diameter landing area for seaplanes. The lake is a popular nationally renowned bass fishing location, while coho salmon are stocked from the Feather River Fish Hatchery.

History

Prior to impoundment by the Oroville Dam, the current main basin of Lake Oroville was the location of the confluence of the North Fork Feather River with the Feather River (39°33′20″N 121°28′0″W / 39.55556°N 121.46667°W / 39.55556; -121.46667) and the now-inundated towns of Bidwell (39°33′25″N 121°27′56″W / 39.55694°N 121.46556°W / 39.55694; -121.46556) and Land (39°33′13″N 121°28′04″W / 39.55361°N 121.46778°W / 39.55361; -121.46778). Completed in 1968, Oroville Dam is an earthen dam and is the tallest dam located in the United States, measuring over 770 feet (235 m) high and 6,920 feet (2109 m) across. The dam was the largest earth-fill dam in the world until succeeded by Aswan High Dam in Egypt. It was built by the California Department of Water Resources as part of the California State Water Project. The dam houses the Edward Hyatt Powerplant, an underground hydro-electric plant that was completed in 1967. Six generators are used to provide a maximum generating capacity of 819 MW.

Oroville Dam

Oroville Dam is an earthfill embankment dam on the Feather River east of the city of Oroville, California in the United States. At 770 feet (230 m) 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 (4.4 km³), and is located in the Sierra Nevada foothills east of the Sacramento Valley.

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

Lake

A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean (except for sea lochs in Scotland and Ireland), and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. However most lakes are fed and drained by rivers and streams.

Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.

Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric power generation or domestic water supply, or for aesthetic or recreational purposes.
