NORTHERN CALIFORNIA – A week after its condition led to a evacuation order for nearly 200,000 Sacramento Valley residents, repair work on the Oroville Dam’s emergency spillway continues.
The California Department of Water Resources said the dam’s outflows on Saturday were reduced from 70,000 cubic feet per second to 55,000 cubic feet per second to allow assessment teams to view debris buildup and dredge debris piles below the flood control spillway.
Even with the recent storms, officials said the reduced outflow continued to outpace the inflow into the reservoir.
Lake elevations continue trending downward and had fallen to 854 feet by 4 p.m. Saturday, officials said.
As runoff flows into the reservoir, officials said 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, the Department of Water Resources reported.
Rock, aggregate, and cement slurry continue to be placed into areas affected by erosion. Officials said this work will continue 24 hours a day.
On Saturday crews also worked to construct a barge to carry excavation equipment that will dredge debris and sediment that has built up below the flood control spillway, the agency said.
