With an uncertain future and a concerned public, new changes to the state’s water control manual made their way before the Butte County Board of Supervisors on Tuesday with the hope of garnering favor for public safety. Oroville Mayor David Pittman was joined by Oroville Dam Advisory Commissioner Robert Bateman as they presented the proposed changes by the U.S. Army Corps of Engineers to the board as well as their concerns about potential flooding. As it stands, the spillway is graded to handle flows up to 350,000 cubic feet per second, but that doesn’t necessarily mean the levees downstream can sustain that kind of force. “In 1997, we had a flow of 160,000 cubic feet per second,” Pittman said. “At the Bedrock Park point, we had leakage through the levee that were able to successfully flood fight, but we don’t know how many times we can do that again.”
