OROVILLE (CBS13) – Unexpected damage to the Oroville Dam spillway has prompted officials to stop water releases.
Operators increased their water releases at the dam on Tuesday as a significant storm rolled through Northern California. However, as peak water releases started happening around noon, people started noticing some concerning signs.

Recent releases have made enough room for this week’s predicted rain, and officials say there’s no structural threat to the dam itself.
Witnesses who posted video to Youtube from the scene saw pieces of concrete being washed away.
“We were just alerted by officials to not be here because there seems to be an issue with the spillway,” the witness says in the video. “This is not normal.”
