Dam, Spillway. 水壩, 溢洪道

The Oroville Dam spillway releases 100,000 cubic feet of water per second down the main spillway in Oroville, California on February 13, 2017. Almost 200,000 people were under evacuation orders in northern California Monday after a threat of catastrophic failure at the United States' tallest dam. Officials said the threat had subsided for the moment as water levels at the Oroville Dam, 75 miles (120 kilometers) north of Sacramento, have eased. But people were still being told to stay out of the area. (Photo by Josh Edelson/AFP Photo)
