Managing & Protecting California’s Water Resources
The Department of Water Resources (DWR) is responsible for managing and protecting California’s water resources. DWR works with other agencies to benefit the State’s people and to protect, restore and enhance the natural and human environments.
DWR Reducing Spillway Outflow to Zero for Debris Removal
On February 27, DWR will gradually reduce Lake Oroville flood control spillway outflows from 50,000 cubic feet per second (cfs) to zero. The reduction will allow workers to remove debris at the spillway’s base and reduce water surface elevation in the diversion pool. This is necessary to begin reoperating the Hyatt Power Plant. Once operational, the plant can discharge roughly 14,000 cfs, which will allow for better management of reservoir levels during spring runoff season. Since February 12, DWR has reduced water levels in Lake Oroville from 901 to 838 feet. DWR is actively monitoring the status of the dam, spillways, Hyatt Power Plant, related structures, and progress of repairs, which continue 24 hours a day.
