The Corps upgraded the dam’s status from “low to high urgency of action,” according to a press release.
The 200-foot high dam met design standards when it was built in 1971, but the Corps said a recent risk assessment showed that water from an extreme storm or flooding event could exceed those standards and overtop the dam.
“The dam has never experienced spillway flow or a flood event that has loaded the dam significantly,” Col. Aaron Barta, commander of the Corps’ Los Angeles District, said. “This is a storm that is unlikely to occur, but it is nonetheless a real possibility and one we must be prepared for.”
