| Subject: Whatever the government touches, turns to shit: 20% of dams in populated areas lack emergency plan Tue Feb 14, 2017 12:22 am | |
| As the nation's 84,000 dams continue to age, a growing number of people downstream are at risk, experts say.
That's not only because of older infrastructure but also because of population growth around some of the dams. More than a quarter were developed primarily for recreational purposes, according to National Inventory of Dams data from 2016. "The nation’s dams are aging, and the number of high-hazard dams is on the rise," according to a 2013 report from the American Society of Civil Engineers. "Many of these dams were built as low-hazard dams protecting undeveloped agricultural land. However, with an increasing population and greater development below dams, the overall number of high-hazard dams continues to increase." That problem was highlighted this week as nearly 200,000 people evacuated an area near California's Oroville Dam, about 150 miles northeast of San Francisco. California water officials were worried that erosion they discovered Sunday at the top of its emergency spillway could send a 30-foot tall wall of water down the Feather River and through the Northern California cities of Oroville, Yuba City and Marysville.
