The Oroville Dam, which is the tallest and one of the largest earthen dams in the world, was completed in 1968 and stands 770 feet high with a crest 6,920 feet long. Over 80 million cubic yards of material were needed to build the Oroville Dam.
A giant cavern (almost as large as the State Capitol Building) was hollowed out to hold six power generation units beneath the dam. Coupled with four additional units in the Thermalito Power plant, more than 2.8 billion kilowatt-hours of power are generated annually.
Oroville is best known for its abundance of recreational opportunities. Lake Oroville, which was created via the construction of the Oroville Dam, is one of the recreational gems of California. With nearly 16,000 surface acres of water and 167 miles of forested shoreline, hundreds of campsites, world-class fishing, boating, sailing, fishing, picnicking, hiking, biking, horseback riding, fish hatchery tours, educational exhibits, scenery and wildlife, Lake Oroville is truly the great outdoors on a Western scale. It is also the second largest reservoir in California, second only to Lake Shasta. Lake Oroville is not overly crowded, and easily accessible by several highways.
