“He had about a 5-minute notice, with no prior warning the day before,” Scott Angel, one of Kenny’s brothers, said. Deaths from dam failures have declined since a series of catastrophic collapses in the 1970s prompted the federal and state governments to step up their safety efforts. Yet about 1,000 dams have failed over the past four decades, killing 34 people, according to Stanford University’s National Performance of Dams Program.
An Associated Press investigation has identified at least 1,680 dams in 44 states and the U.S. territory of Puerto Rico that are considered to be high hazard and in poor or unsatisfactory condition. A dam is listed as high hazard if its failure is likely to result in people being killed. The dams and their date of last inspection have been plotted on an interactive map developed by location intelligence company, Esri.
Nebraska was among the states hardest hit by storms and floods this year that have caused an estimated $1.5 billion in damage to roads, dams, utilities and other infrastructure in 28 states, according to an AP analysis.released by the White House last year noted growing frequency and intensity of storms as the climate changes. That can push some dams beyond what they were designed to handle.
Dam conditions are supposed to be rated as unsatisfactory, poor, fair or satisfactory. But the ratings are subjective — varying by state and the interpretations of individual inspectors — and are not always publicly disclosed.
