State engineers have found new damage to the Oroville Dam spillway, although not as much as they’d feared, after conducting two test releases to see how much water the scarred facility could handle, the state said Thursday. Meanwhile, reservoir levels continued to climb behind the critical flood-control structure. The gash that was discovered Tuesday grew by another 50 feet after engineers released water for a combined six hours Wednesday and early Thursday, according to Department of Water Resources spokesman Doug Carlson. “They found additional damage to the spillway, which was predicted,” Carlson said.
