Work continues to repair damaged dam in California

Work continues to repair the damaged main spillway of the Oroville Dam on Thursday, Oct. 19, 2017, in Oroville, Calif. California officials say repair costs at the nation's tallest dam will be nearly double the original estimate of $275 million. The main spillway and emergency spillway suffered significant damage during storms last February, prompting fears of massive flooding. [Photo: AP/Rich Pedroncelli]
