Long Description:
The pictures here more reflect the California Drought of 2014. Normally the lake surface covers over 15,800 acres. At 770 feet (230 m) high, the Oroville Dam is the tallest dam in the USA. Wikipedia describes the dam:

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.

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 1990. 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.
