Comments Off on Damaged Oroville spillway in California prompts mass evacuations

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.

California is battling one of the strongest winter storms the state has seen in years, prompting Gov. Jerry Brown to declare a state of emergency in 50 counties. After a brutal five-year drought , the state needs rain but the severe weather has also led to mudslides, flooding, and evacuations. Southern California in particular has been hit with a deluge of rain , breaking records in some areas. Los Angeles County coastal areas received most of the brunt of the storm. Long Beach Airport actually saw a new rainfall record of 3.87 inches. National Weather Service meteorologist Brett Albright said some parts of southern California received up to four inches. He told the Los Angeles Times, “Today was very intense. It’s not a normal event…It’s not often we see higher rainfall totals on the coast than in the mountains.” Related: California storms could herald the end of punishing historical drought The storms continue the trend of more rain than usual in California. Since October 1, 2016, downtown Los Angeles has received over 13 inches of rain, which is 216 percent more than normal for this time period, or around 6.26 inches according to the National Weather Service. Swaths of southern California experienced extreme events connected to the storm. Rockslides in Malibu closed roads. In Isla Vista, close to Santa Barbara, a patio and a cliff crashed into the ocean. Residents were told to evacuate in Duarte, Glendora, and parts of Santa Barbara County and Orange County, where 2016 wildfires left behind burned areas that are more susceptible to mudslides. One death in Pomona has been likely connected to the storm; a driver lost control of their car and crashed while driving in heavy rain in the afternoon. Rainfall is supposed to continue into this week, and some areas could see four to six inches of rain during the next couple of days. The state of emergency will help secure state and federal funds to help those struggling with what Gov. Brown called “conditions of extreme peril.” Via the Los Angeles Times Images via Flickinpicks on Flickr and nosha on Flickr
