Hundreds of California dams are in poor condition. Almost 700 dams in the state are classified as high hazard dams. If one of those dams fails, it could cause deaths and significant property damage. Of the nearly 1,500 dams surveyed in California, 50% of them did not have an emergency action plan. Los Angeles County has the most high hazard dams in the state. The state increased its dam safety budget after the Oroville Dam’s main spillway collapsed in 2017.
