Oroville Dam: Spillway Is 70 Percent Filled With One Month To Go

The wide-open middle section of the Oroville Dam spillway is 70 percent filled, with the deadline for this season’s work fast approaching. The contractor Kiewit Infrastructure West Co. remains on track to have the 3,000-foot spillway ready to pass flows of 100,000 cubic-feet per second by Nov. 1, said Jeanne Kuttel, chief of engineering for the state Department of Water Resources, in a media call on Wednesday morning.
