Evacuation orders for nearly 200,000 people living below the tallest dam in the United States remained in place early on Monday after residents were abruptly told to flee when a spillway appeared in danger of collapse. The California Department of Water Resources said on Twitter at about 4:30 p.m. PST that the spillway next to the dam was “predicted to fail within the next hour.”
