Work Continues Round The Clock On Damaged Oroville Spillway

Oroville, CA…Flow from the Oroville Dam Flood Control Spillway will remain at 55,000 cfs and continue to
outpace the inflow encountered. The reduction in flow has allowed assessment teams to view debris buildup and dredge debris piles below the flood control spillway. Lake elevations continue trending downward and had fallen to 852 feet, by 4:00 this morning, 48 feet below the emergency spillway. As runoff flows into the reservoir, water levels will likely fluctuate but will remain within acceptable and typical depths during times of storm activity. Despite current inclement weather, work continues on the area below the spillway, the monoliths, access roads, and various eroded areas created by emergency spillway runoff. Rock, aggregate, and cement slurry continue to be placed into areas affected by erosion. This work will continue 24 hours a day.

DWR continues to aggressively monitor the status of the dam, spillways, the Hyatt Power Plant, related structures, and progress of repair activities.
