BTW, this lack of upkeep on infrastructure is apparently a nationwide problem, with one seriously shaky dam in Texas that could put the whole city of Dallas under 50 feet of water!
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.
But what the Corps tells itself about the Lewisville Dam is different from what it tells the public. “We want to get the message out that there’s a potential for something bad to happen, but we don’t want to unduly panic the public,” says an official involved in the communications. “So we sugarcoat the message a bit.”
