Billed as the largest earth-filled dam in the world, it is the tallest dam in the United States at 230m/770ft, and the top of the dam spans 2,110m/6,920ft. The view over the Sacramento Valley is stunning, especially after a good rainstorm. For security reasons, you can't park directly on the top of the dam. There are also quite impressive tours under the dam showing the massive hydroelectric turbines, although the hours and offer of these tours are unpredictable.
Oroville Dam is an earthfill embankment dam on the Feather River east of the city of Oroville, California, in the Sierra Nevada foothills east of the Sacramento Valley. At 770 feet (235 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 reservoir in California, capable of storing more than 3.5 million acre-feet (1.1×10^12 US gal; 4.3×109 m3).
