Standing atop the crest of the Lewisville Dam last February, his eyes fixed on the Dallas skyline, Vazquez grew silent as he thought about the catastrophic consequences of a breach. I think about it a lot, he says.
With a full reservoir behind it, a 65-foot-tall flood wave traveling 34 mph would quickly inundate a wide swath of Lewisville, Coppell, Carrollton, Farmers Branch, Irving, Las Colinas and other communities bordering the Trinity River.
The wave would sweep everything in its path the Lewisville dump, water treatment plants, LBJ Freeway, the Bush Turnpike, Interstate 35E, the State Highway 121 Tollway, Love Field, the Hospital District, office complexes, senior citizen centers, shelters, schools, playgrounds and 53,000 other structures.
Like a tsunami, the wave would submerge downtown Dallas in roughly 50 feet of water, the Corps estimates, causing more than $21 billion in property damage, before continuing south down the Trinity River toward the Gulf of Mexico. It would be a much bigger magnitude to the Dallas area than Hurricane Katrina was to New Orleans, says Vazquez. Its a nightmare scenario.
