Independent forensic investigations - reflections on Oroville Dam

An aerial view of the damaged Oroville Dam spillway site and the huge debris field in the diversion pool just below the spillway. The California Department of Water Resources gradually reduced the outflow from the spillway from 50,000 cubic feet per second to zero on 27 February 2017. The reduction allowed work to begin to remove the debris and reduce water surface elevation in the diversion pool, so the Edward Hyatt Powerplant could go operational.
