State engineers have discovered new damage to the Oroville Dam spillway in Northern California. Earlier this week, chunks of concrete went flying off the emergency spillway, creating a 200-foot-long, 30-foot-deep hole. After releasing water to test how much the facility could still handle, state engineers told the Sacramento Bee newspaper that they found the hole had grown by an additional 50 feet. They said the new damage wasn’t as bad as they’d expected. Officials with the Department of Water Resources, which operates the dam, say the dam is safe and doesn’t threaten communities downstream. But reservoir levels are continuing to rise behind the critical flood-control structure.
