Dams Throughout the U.S. Fail to Meet Safety Standards
In 2016, officials estimated that the repairs needed to bring the country's dams up to safety standards would cost $60 billion. Of that, about $20 billion would need to be prioritized for dams deemed "high hazard," or likely to cause loss of life in case of failure. The Oroville dam, built in the 1960s, has high hazard potential.
A bill pending in Congress would make grants available for the rehabilitation of publicly owned dams that don't meet safety requirements. But more than half of the dams in the United States are privately owned—including the Twentyone Mile Dam in Elko County, which was built in the early 1900s.
