Dam Failure Potential

Looking for some light reading for your leisurely weekend?

“Even before last spring’s rains, the Lewisville Dam was listed by the Corps as the eighth-most-hazardous in the country. Recent rains have made it worse, the Corps says.

The dam is so unstable now that the Fort Worth District is considering asking Corps headquarters to upgrade its risk classification to the highest: “critically near failure” — that is, “almost certain to fail under normal operations … within a few years without intervention,” according to a Corps document.

…..

Only 34 miles upstream from Dallas, the Lewisville Dam holds back 2 million acre-feet, or 2.5 billion tons, of water when the lake is full. If the dam failed, the magnitude of all that water unleashed from Lake Lewisville down the Trinity River would dwarf the worst dam disaster in American history.”
