Intense work to reinforce the emergency spillway of damaged Oroville Dam in California continues and the level of the reservoir continues to decrease. At current rates, it is projected to possess the capacity to absorb anticipated inflows due to forecasted inclement weather. The mandatory evacuation order was reduced to a warning.
More than 125 construction crews are working around the clock, and are placing 1 200 tons of material on the spillway per hour using helicopters and heavy construction equipment, California Department of Water Resources said. The area is being continually monitored from the ground and by the use of drones.
DWR continues to regulate outflow, to reduce water levels in the reservoir, support construction activities, and protect the Hyatt Power Plant.
