The Prado Dam in Corona is vulnerable to a "significant flood event" that could breach the nearly 80-year-old dam and threaten dozens of cities downstream, federal engineers reported Wednesday.
The U.S. Army Corps of Engineers reported this week that it has upgraded Prado Dam's characterization from moderate urgency to high urgency as a result of a recent review. . . .
However, the latest examination determined that a significant flooding could indeed breach the spillway, which would put the approximately 1.4 million people who live in 29 cities downstream of the dam in possible danger, along with $61 billion worth of property.
