Oroville, Calif. February 16, 2017 – DWR has begun reducing outflow from the Oroville Dam flood control spillway to support the removal of debris from the diversion pool located near the spillway.
Removal of debris from the diversion pool further protects, safeguards, and provides for the eventual reoperation of the Hyatt power plant.
This reduced outflow still provides for the reduction of reservoir levels within the timeframes prescribed by the DWR.
These actions are consistent with typical reductions in water flow encountered when head pressures behind food control spillway gates are reduced as reservoir levels fall.
As water flow rates change, automatic messages are generated by the DWR Project Operations Center and are distributed to Area Emergency Managers and the media, as per normal operating procedures.
