Risk Level Raised On Integrity Of Dam In Southern California

Federal engineers are raising alarms that a “significant flood event” could compromise the spillway of Southern California’s aging Prado Dam and potentially inundate dozens of Orange County communities from Disneyland to Newport Beach. After conducting an assessment of the 78-year-old structure this month, the U.S. Army Corps of Engineers announced that it is raising the dam’s risk category from “moderate” to “high urgency.” “Our concern right now is about the concrete slab of the spillway and how well it will perform if water were to spill over the top of the dam,” said Lillian Doherty, the Army Corps’ division chief. “We will determine whether or not it is as reliable as it should be.”
