(KRON) Heavy runoff from January and February’s storms have damaged Lake Oroville’s spillway.
Video shows massive chunks of concrete have eroded from the dam, the hole is 200-foot-long, 30-foot-deep.
Flood warnings are in place in swaths of northern and central California as another system moves ashore.
The Department of Water Resources stopped the flow of water out of the reservoir on Tuesday so inspections could happen.
Experts say there is no danger of the dam failing but repairs need to be made.
Lake Oroville still has 20 percent capacity left so there is plenty of space for runoff to fill the reservoir.
DWR continues to assess the concrete erosion on the Oroville Dam spillway. No imminent threat to the dam or public. https://t.co/WNFPLGQaaA. pic.twitter.com/boOo39PBdD— CA – DWR (@CA_DWR) February 8, 2017
