Water rushes down the Oroville Dam spillway, Thursday, Feb. 9, 2017, in Oroville, Calif. State engineers on Thursday discovered new damage to the Oroville Dam spillway, the tallest in the United States, though they said there is no harm to the nearby dam and no danger to the public. Earlier this week, chunks of concrete went flying off the spillway, creating a 200-foot-long, 30-foot deep hole. (AP Photo/Rich Pedroncelli)
