The Oroville-Thermalito Complex is a storage and pumping operation on the Feather River. The facilities include three power plants (Hyatt Powerplant, Thermalito Diversion Dam Powerplant, and Thermalito Pumping-Generating Plant, two of which can either pump water or generate power), the State Water Project's largest reservoir (Lake Oroville), a forebay and afterbay, a fish hatchery, and a visitors center. 

As water leaves this region, it flows down Feather River and Sacramento River channels to the Sacramento-San Joaquin Delta.
