California audit finds dozens of aging dams in poor condition ahead of El Niño winter
PN Team • 3 weeks ago
A state audit released this week found 57 California dams in poor or unsatisfactory condition as of May, a number expected to rise as officials reevaluate aging infrastructure. Of these, 40 are rated high or extremely high hazard and cluster near densely populated areas including the Bay Area, San Diego, and Los Angeles. The auditor warned these dams could collectively endanger up to 1.5 million people and cause more than $265 billion in economic damage if they failed, with the risk heightened by an approaching El Niño winter expected to bring heavy rain.
The report criticized the California Department of Water Resources for never using enforcement powers granted in 2017, after the Oroville spillway failure, despite referring 44 dam owners for violations. Most dam owners lack funds for repairs, which the audit estimates could cost $28 billion statewide, far outpacing recent funding infusions. The auditor urged lawmakers to set repair deadlines and expand condemnation authority. The Department of Water Resources said it disagrees with some findings but is reviewing recommendations as it prepares for the wet season.
