Winter storms continue to drench California , and over the weekend people living near Oroville in Northern California faced a crisis. After officials noticed a hole in the emergency spillway at the United States’ tallest dam , around 180,000 residents were ordered to evacuate , some given just one hour to flee their homes. Flooding in the area had been a threat for around a week as the reservoir behind Oroville Dam reached capacity. When the main spillway started eroding, officials opened an emergency spillway that’s never been used since the dam was built in the 1960’s. But then officials noticed the hole, and ordered evacuations on Sunday. Some residents had just one hour’s notice before officials feared the auxiliary spillway could fail, which could precipitate “an uncontrolled release of flood waters from Lake Oroville,” according to the National Weather Service .

But officials said evacuations should continue, and conditions are still perilous. Governor Jerry Brown proclaimed a state of emergency on Sunday for three counties , saying in a statement, “I’ve been in close contact with emergency personnel managing the situation in Oroville throughout the weekend and it’s clear the circumstances are complex and rapidly changing.” During the night evacuation shelters were still being outfitted with blankets and beds, according to NPR. Gizmodo reports residents of Oroville, Wheatland, Marysville, Plumas Lake, Hallwood, and Olivehurst were told to evacuate. According to the Los Angeles Times, if the emergency spillway failed, large amounts of water could gush into the Feather River, which travels through downtown Oroville. Flooding and levee failures would likely follow in the wake of a spillway failure for miles south of the Oroville Dam. Many communities could be flooded if that were to happen.
