According to the Department of Water Resources (DWR), the Oroville Dam flood-control spillway is ready for rain; the half-mile concrete chute will be functional if lake levels rise with a new water release capacity of 270,000 CFS (cubic feet per second). Concrete reinforcement of the emergency spillway will continue through early 2019.

DWR says the last of the concrete slabs on the main spillway will cure over the next month, but are able to handle water if necessary. The $1.1 billion reconstruction project is a result of heavy rain damage to the main spillway and failure of the emergency spillway that caused 188,000 Sacramento Valley residents to evacuate. It is estimated that over 1.2 million cubic yards of concrete have been used for this major reconstruction project.
