Oroville Dam spillway shut down again as state officials work on long-term plan

By Dale Kasler and Ryan Sabalow

The operators of Oroville Dam acknowledged Monday they might not be able to permanently repair the dam’s battered main spillway in time for the next rainy season, but said they’re confident the fractured structure will be usable.

Engineers expect to have this summer’s repair plans largely in place by early next week for the concrete spillway, said Bill Croyle, the acting director of the state Department of Water Resources.

“If I have anything to say about it, we’ll have a spillway to use by Nov. 1,” Croyle said, referring to the expected start of the next rainy season. “Whether that’s a permanent or temporary structure, it hasn’t yet been decided.”

Monday’s briefing also served to announce that the dam’s operators were again shutting off the water flowing down the spillway. The structure had been releasing water at about 40,000 cubic feet per second since March 17. The releases would be dialed back to zero by Monday night and could stay that way for the next 15 days.

Croyle said the shutoff will enable DWR crews to dredge more debris from the Feather River channel at the base of the spillway and make additional repairs to the dam’s hydroelectric power plant. The plant was shut off temporarily Monday as well, although Croyle said it was expected to resume releasing water Monday afternoon.
