Dam Safety

This is part four of a series looking at the infrastructure of dams in Texas, and what can be done to improve it. You can find part one here, and part two here, and part three here.

In a peaceful, wooded corner of Bastrop County, Texas sits one of the unluckiest dams in the state. In 2011 the Labor Day Wildfires burned soil and vegetation around Clear Springs Lake and its earthen dam. Then, half a year later, a massive rainstorm hit. Water poured over the structure and wrecked havoc on an already crumbling spillway.

“Our poor little dam has gone between being scorched to being flooded in a matter of six months,” Bruce Bar, a floodplain engineer and the manager of the community’s dam told StateImpact Texas. “So it’s handled about as much as nature can throw at it.”

In 1978 a massive storm hit the West Texas town of Albany. It dumped 23 inches of rain in just eight hours. Waters caused 9 deaths, flooded hundreds of homes, and broke through a local dam. Troy Henderson, who now works on the Brownwood Texas Lake Patrol, says since then he’s followed a simple rule.

“If I were to build a home somewhere, I’d make sure that if it was downstream from a lake that their dam is property maintained,” he told StateImpact Texas, “and the reason I say that is, I lived in Albany in 1978.”

In 2008, the Texas State Auditor’s office released the kind of report that keeps public officials awake at night.  It found that state regulators were not ensuring the proper maintenance of thousands of dams in Texas. The audit found that state inspectors had never visited hundreds of dams that could cause loss of life if they failed.

Of the 1,880 dams inspected by the Texas Commission on Environmental Quality since 2008, 245 were found to be in bad condition, according to the TCEQ. Around 2000 of the state’s dams were built with federal help in the wake of the great drought of the 1950s. Almost all of those are now past or nearing their projected 50 year lifespan, according to the American Society of Civil Engineers.

Statistics like these don't come as a surprise to the people who work with dams in the state of Texas.
