About Lake Oroville
Oroville Dam holds back the Feather River as the headwaters storage of California's State Water Project, operated by the Department of Water Resources rather than a federal agency. At 770 feet it is the tallest dam in the United States, behind the state's second-largest reservoir at more than 3.5 million acre-feet. DWR runs it for supply, hydropower, and winter flood control.
Total capacity is 3.42M af, over the past five years storage has ranged from 787,578 af to 3.54M af.
