Dam Structural Health Monitoring
Dam structural health monitoring is a vital necessity for modern hydroelectric facilities. Hydroelectric dams provide clean energy and support economies worldwide, but they face constant environmental pressures and seismic threats. Therefore, site operators must prioritize continuous safety assessments to prevent catastrophic infrastructure failures. QuakeLogic offers complete, real-time…
The 1977 Johnstown Flood: A City Struck by Disaster
On the night of July 19, 1977, Johnstown, Pennsylvania, was once again devastated by a catastrophic flood, marking the third major disaster in the city’s history. Known for its resilience, Johnstown had already endured the infamous floods of 1889 and 1936. However, the 1977 flood came as a stark reminder of nature’s unpredictability, inflicting widespread destruction and a profound loss of…

This is part three 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.
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.”
The Federal Government echoes that advice. In the FEMA booklet “Living with Dams,” the agency urges people to “ask questions” about the condition and hazard rating of dams near their homes.
But here in Texas, no one needs to answer those questions.

Gov. McDonnell’s dam safety program causes minimal affect in local Shenandoah dam improvement plans
Katherine Kylie McKenna
Staff Writer
(RICHMOND) Long awaited dam reconstruction plans have been put on alert in Shenandoah County and have coincided with a recently proposed Dam Safety bill in the Virginia General Assembly.
“We had an engineering forum make five or six options for improvement plans,” said Craig Orndorff, one of Shenandoah County’s two elected directors for the Lord Fairfax Soil and Water Conservations District. “We planned to reveal them to the public on February 8, but right now we may not be having that meeting,” he said in a January 18, 2012 interview.
The Lord Fairfax Soil and Water Conservations District has made scheduled plans to undergo major improvements on the Lake Laura and Birdhaven Lake dams in Shenandoah County. These improvements would bring these dams up to the Virginia dam qualifications that were set in the earlier part of the last decade, Orndorff said. Changes were made but a hold up of state money restrained them from making all necessary changes, he said.
“Now we’re near the top of the list,” Orndorff said.
Water safety may seem to be a distant concern when connected with thoughts of seasonal warm weather trips to Virginia beaches and the James River. But the implementation of a Virginia dam safety program has brought a different version of water safety to the attention of Virginia General Assembly members. The Senate Bill 253 and House Bill 293, both titled “Dam safety; consultation with Department of Emergency Management,” were introduced by Senator Bryce Reeves, R-17, and Delegate Edward Scott, R-30, respectively.
This joint bill, proposed on January 10, would require the Soil and Water Conservation Board to consult with the Department of Emergency Management in implementing part of Gov. Bob McDonnell’s dam safety program. The board shall coordinate all dam safety activities including the maintenance of structures, the maintenance of a repository for record drawings of all structures, the inventory of safety inspection reports and a second repository for all dam safety emergency action plans.
“We are not only looking at structural safety, but also public safety,” Scott said. “We’re looking at what other services in the community would need help if a dam became impaired.” There are a vast number of dams throughout the Commonwealth of Virginia and faulty structures can affect entire communities in times of extreme weather.
The introduction of a bill might set plans back a little, Orndorff said, but the correspondence with local first responders is already part of protocol. The reaction to dam impairment is not expected to change much on the local level, he said, the legislation has mostly to do with the state boards.
“The improvements we’re doing are largely to handle extreme issues,” Orndorff said. “This bill is more of a clarifying amendment that would ensure emergency contacts are consulted.”
Scott agreed in saying that their main goal was to come up with a streamline way to bring the conversation together between the two state departments. If state regulations can require the correspondence that many local boards already practice, then the assurance of proper safety response may become statewide.
“The emergency department may not be faster in responding,” Scott said, “But as we’re doing the planning, they understand the local emergency steps that must be taken.” The bill is an out product of McDonnell’s reform plan, so it is likely to receive support, Scott said. He sees this proposal as an asset and assurance that within state government there is the appropriate conversation going on.
Orndorff concluded that he doesn’t think the bill will affect local sections as much as overall state guidelines, but they may face some short-term issues. He planned to forward this legislation to several of his colleagues.
“It looks like this will primarily affect the state, and what happens in the state may trickle down to us,” he said.
