Seven Oaks Dam
From Wikipedia, the free encyclopedia
The Seven Oaks Dam is located on the Santa Ana River, 4 miles (6 km) northeast of Redlands, California. It was constructed by the United States Army Corps of Engineers as a flood control dam. It cost $250 million to construct and at the time of its completion in November 1999, it ranked as the 10th largest earthfill dam in the United States.
Construction of the Seven Oaks Dam began in August 1994. When it was completed, the height of the dam was 550 ft (168 m) and was over 2,200 ft (670 m) wide at its base; 43,000,000 yd³ (33,000,000 m³) of earth and rock were required to build it. The dam sits virtually on top of the San Andreas Fault and is designed to withstand a |magnitude 8.0 earthquake. The dam forms Seven Oaks Reservoir, which has a capacity of 147,970 acre-feet (182,521,000 m³).
