Lake Oroville

Lake Oroville is a massive reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada.


Known as the second-largest reservoir in California, Lake Oroville is a vital part of the California State Water Project. It serves multiple purposes including storing water, providing flood control, recreation, and freshwater releases to help control the salinity intrusion into the Sacramento-San Joaquin Delta. The lake is also important for protecting fish and wildlife in the area.
