Oroville Dam is America’s tallest dam. Located in the foothills of California’s Sierra Nevada mountains, the dam stands 770 feet tall and measures 6,920 feet long at its crest.
Construction began in 1957 and was completed in 1968. Over 80 million cubic yards of material were used to build the dam, or enough to build a two-lane highway around the globe. Oroville Dam is an earth-filled dam made of clay, sand, and gravel left from early 20th century gold dredging.
Lake Oroville was created by the construction. The reservoir holds 3.5 million acre-feet of water and features 167 miles of shoreline.
Oroville Dam is part of a complex system designed to distribute water and generate electricity. Water gathered from the Feather River watershed is stored in the reservoir for distribution to densely populated cities in dry southern California.
Six power generation units are housed in a giant underground cavern beneath Lake Oroville. The hydro-electric system generates 2.8 billion kilowatt-hours of power annually.
In 1975, a 5.7 magnitude earthquake led to the discovery that Oroville Dam rests atop an active faultline.
