Road project may be doomed by dam
9-19-14 | Cleveland Advocate | By Casey Stinnett
One of Liberty County's road projects has hit a snag. County Road 6494 in the Winter Valley subdivision near Kenefick cannot be re-worked until a privately-owned dam over which it passes is repaired, according to instructions from the Texas Commission on Environmental Quality (TCEQ) as passed on by Rick Bourque of Schaumburg and Polk, Inc. and J. Rice of Public Management to the county commissioners in a workshop held Sept. 9.
The dam was built in the 1980s to create the Winter Valley Estates Lake, and County Road 6494 includes a bridge that spans the dam's spillway.
Since the dam's construction, the concrete structure has eroded. Cracks appear leading down the sidewalls from the bridge above them to the spillway below, and images from Google Earth taken during a dry spell last year reveal the concrete of the spillway to be heavily damaged.
According to information from a TCEQ dam safety workshop held earlier this year, since 1900, 171 dams in Texas have either failed or been damaged because of overtopping or structural issues. Among the examples of dam failures included in one TCEQ workshop session were the failure of 10 dams in Tyler County that broke as a result of extremely heavy rainfall and flooding on Sept. 27, 1996. read more, photos
USDA Farm Bill Investment Funds 150 Dam Rehab Projects
7-21-14 | Farm Futures
USDA will spend $262 million on rehabilitating dams per the 2014 Farm Bill, USDA announced on July 18.
The funding, which will provide rehabilitation assistance for 150 dams in 26 states, can be used for planning, design or construction. The outlay is detailed in the 2014 Farm Bill, which increased the typical annual investment in watershed rehabilitation by almost 21-fold to recognize infrastructure's role in flood management, water supply, and agricultural productivity.
Natural Resources Conservation Service Chief Jason Weller and Rep. Frank Lucas, R-Okla., chairman of the House Committee on Agriculture, recognized the announcement in Oklahoma, where the first full watershed plan and structure was completed by USDA on private lands in the 1940s.
USDA invests $262 million for dam rehabilitation per farm bill outlays.
From the 1940s through the 1970s, local communities using NRCS assistance constructed more than 11,800 dams in 47 states. These watershed management projects provide an estimated $2.2 billion in annual benefits in reduced flooding and erosion damages, and improved recreation, water supplies and wildlife habitat for an estimated 47 million Americans.
In addition to the 150 dam projects that will be funded, 500 dam sites will be assessed for safety through NRCS' Watershed Rehabilitation Program.
The projects were identified based on recent rehabilitation investments and the potential risks to life and property if a dam failure occurred. Overall, an estimated 250,000 people will benefit as a result of improved flood protection made possible by these rehabilitated dams.

Texas Law Reducing Dam Inspections Sparks Criticism
Move Raises Concerns As Drought Threatens to Weaken Earthen Barriers
7-9-14 | Wall Street Journal | By Julia Harte
DALLAS—Texas has stopped inspecting 44% of the dams in the state, following passage last year of a state law that exempted most privately owned dams from safety requirements.
Now, as a drought dries up large portions of the Southwest, some dam-safety experts and officials are questioning the law, saying the dry spell is leaving webs of cracks along the surface of earthen dams that may make them weaker—and prone to triggering floods—when rains eventually fill them up again.
"There are dozens of dams out there, if not more, that potentially could impact people. But you're not really sure until they've been looked at," said John Wolfhope, a civil engineer based in Austin who sits on the National Dam Safety Review Board and who testified about an earlier version of the law.
That view of the legislation is shared by safety officials in surrounding states, whose dams also face a threat from the parched conditions.
State regulators across the Southwest are on heightened alert for dam failures due to the recent prolonged drought. In New Mexico, Colorado and Arizona, all dams are inspected. Those whose failure could kill people are inspected once a year, while dams whose failure could cause economic damage are inspected once every three years.
Following complaints from private owners, Texas lawmakers exempted privately owned dams holding up to 500 acre feet of water, or about 163 million gallons, from state regulation in all but the most populous counties. The changes took place through legislation first approved in 2011 and broadened last year.
Roughly 3,200 dams were exempted. Of those, 216 could cause economic loss, environmental damage or disruption of lifeline facilities if they failed, according to a presentation prepared by the Texas Commission on Environmental Quality.
No other state has deregulated dams like Texas, said Lori Spragens, executive director at the national Association of Dam Safety Officials. The law "just doesn't make any sense from a safety standpoint," she said.
Ralph Duggins, an owner who testified in favor of the change, said he was ordered to carry out $50,000 worth of safety studies on his three-decade-old dam in rural Johnson County after state officials noticed that new houses had been built downstream. read more
Drought among the worst in Texas in past 500 years
5-13-14 | San Antonio Express-News | By Scott Huddleston
SAN ANTONIO — The drought that has South Texas in its grip is among the top five extended dry spells in the past 500 years, and soon may rise to the top three, the state climatologist said Tuesday.
"The question arises, is this something that is going to be the new normal?" state Climatologist John Nielsen-Gammon told the Edwards Aquifer Authority board a day after the year's heaviest rainfall, 2.5 inches, brought some relief, but not enough to even dent the drought.
El Niño conditions resulting from a rise in Pacific Ocean temperatures and historically known to bring more rain to the Southern U.S. "definitely seem to be on the way," he said.
That raises the prospect of a cool, wet winter and up to 5 inches of rain beyond normal, he added.
In the long term, changes in the global climate are expected to produce more rain in Canada, less moisture and flooding in Mexico and more intense weather extremes in Texas, said Nielsen-Gammon, the state climatologist since 2000.
"We're in one of those parts of the world where we could see both worse droughts and worse floods," he said. read more
In Central Texas, Drought Threatens Hydropower
3-10-14 | The Texas Tribune | By Jim Malewitz
Central Texas' years-long drought could eventually snuff out a renewable power source that fueled its early growth: hydropower.
Faced with dwindling water supplies, the Lower Colorado River Authority, which supplies water and energy to much of Central Texas, is limiting downstream water releases for activities like rice farming. Aside from stirring controversy among water users, the changes have also shrunk the amount of electricity the agency generates from its six Colorado River dams.
"Your hydropower becomes an innocent bystander of the conditions around it," said Robert Cullick, a former LCRA spokesman who is now a consultant.
LCRA's more recent curbs on downstream releases has sped hydropower's decline.
The agency now generates just about a third of the hydropower it did in 2011, the last year that most rice farmers received Colorado River water.
If the drought persists, said Ryan Rowney, executive manager of water operations at the LCRA, water levels could "within several years" plummet below levels needed to turn the agency's hydropower generators.
"We have models and things, but we don't truly know how quickly the lakes will fall," Rowney said.
As a low-cost, no-pollution energy source that can be quickly turned on and off, hydroelectricity is a coveted power source, said Webber, but it's a "pretty limited option" for Texas, whose geography and climate are ill-suited for it. And since the state long ago dammed up its best rivers, it is unlikely to grow much — if at all — in the future.
"You're driven by Mother Nature," he said. "And Mother Nature has already voted." read more
If Rains Refill Reservoirs, Can Texas' Dams Hold Up?
11-26-13 |National Pubic Radio/Texas | By Michael Marks
Recent rain and snow haven't been enough to replenish Texas' water supply. Years of drought have taken their toll on the state's reservoirs, some of which remain nearly empty.
Eventually, the reservoirs should fill back up. (Hopefully.) But it's unclear if Texas' infrastructure will be able to hold back the waters once that happens.
Experts say that Texas' dams have incurred severe damage because of the drought and subsequent rains. Dry conditions can cause cracks to form in the dams, which undermines their structural integrity.
This is especially true of earthen dams that are made out of soil and other natural materials, according to Warren Samuelson, head of the Dam Safety Program at the Texas Commission on Environmental Quality.
"[The drought] causes the dams to move, sort of," says Samuelson. "Cracks are created because it's dry, and so you have the shrinking and swelling of the soil because they're earthen structures."
Nearly 97 percent of the dams in Texas are earthen dams, according to the U.S. Army Corps of Engineers' National Inventory of Dams.
Drought can also crack concrete dams by shifting the soil. As the ground around the dam moves, Samuelson says that cracks will "develop through the bottom, up from the concrete."
And those problems can be exacerbated by rain. Rain causes two main issues for cracked dams: it increases the size of the cracks, and it increases the amount of water that the dam must hold back.
"You get a rainfall event, all the water goes down in the crack. And then you have a more fluid situation in the dam, which can result in slides, and possibly even failure of the dam," Samuelson says.
Samuelson says he has found cracks that are as large as five inches across by four feet deep. But according to him, that's not something people think about when they're building a house or a business. read more

Dam Safety Rule Changes May be Short Lived
10-13 | By Bruce Barr, CFM, TAC County G.I.S. Analyst
On Sept. 26, the House Committee on Environmental Regulation, chaired by Representative Wayne Smith, heard testimony regarding the implementation of dam safety rule changes passed during the last legislative session. The interim charge states that the committee shall: "Examine the impact on dam safety of provisions passed in HB 2694 (82R) and develop recommendations, if any, regarding risk to downstream property and life. read more
In October 2013, National Public Radio's StateImpact Texas team produced a four-part series about hazardous dams in Texas, the 2013 changes to exempt some dams from inspections and EAPs, and secrecy regarding who owns dams and their hazard classification.
1. Why So Many Dams In Texas Are in Bad Condition
10-14-13 | NPR | By Mose Bruchele
Of the 1,880 dams inspected by the TCEQ since 2008, 245 were found to be in bad condition, according to the Texas Commission on Environmental Quality. Around 2,000 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. listen and read more.
2. How Hundreds of 'Significant Hazard' Dams Escape State Inspection in Texas

Aging and lack of maintenance are affecting both private and public dams in the state, but so is an absence of money says Warren Samuelson, the Manager of the Dam Safety Program for the Texas Commission on Environmental Quality. "What we need is what some other states have done, they've designated a pot of money where owners can come in that have issues with their dam and try to get some funds based upon whatever criteria is set up," Samuelson said. listen and read more
Lewisville Lake Dam in need of repairs, officials say
09-03-13 | Dallas Morning News | By Wendy Hundley
The U.S. Army Corps of Engineers is looking for ways to shore up the 58-year-old Lewisville Lake Dam after a study found that its deteriorating condition put it in a "very high risk" category.
Officials stress that there's no immediate danger of the dam breaching. But the level of concern is heightened because of the density of the population downstream. "Dam failure is not likely, not at all," Anita Branch, project engineer for the corps' Fort Worth District, said at a public meeting in Lewisville. The meeting that drew about 45 residents sought public input as the corps begins a three-year initiative to determine the best ways to repair the 6-mile-long structure. read more

Dallas proposal would allow drilling near levees
05-20-12 | Dallas Morning News | by Randy Lee Loftis, Environmental Writer
The U.S. Army Corps of Engineers is so concerned that natural-gas drilling and hydraulic fracturing might damage its dams and levees that it doesn't want any wells within 3,000 feet of them. Not so the city of Dallas. Already, it has collected millions of dollars by leasing out possible gas-drilling land that's slap up against its Dallas Floodway levees — land that would be undrillable if Dallas adopted the corps' policy. read more
Corps and Dallas city officials explain cheaper fixes for Trinity River levees
10-04-11 | Austin American-Statesman | by Steve Thompsonand Michael A. Lindeberger
The U.S. Army Corps of Engineers has dropped its opposition to a cheaper fix for the Trinity River levees long supported by Dallas city officials, announcing Monday that the city may use a less-expensive material to erect seepage walls needed to protect the troubled levees. That will bring the cost of repairs to Dallas' flood-protection system down by millions of dollars. What it doesn't guarantee, however, is that the repairs will meet the Federal Emergency Management Agency's requirement that the levees protect Dallas from a 100-year flood. read more
Most Texas dams would go unregulated under House-passed bill
05-08-11 | Austin American-Statesman | by Tim Eaton
The vast majority of dams in Texas would no longer have to meet state safety requirements if a Fort Worth lawmaker gets his way.
The proposal by Rep. Charlie Geren to end state oversight of most dams came up on April 19 during a long day of debate on a bill to continue the operations of the Texas Commission on Environmental Quality, which regulates private and public dams. Geren, a Fort Worth Republican, portrayed it as a tweak in the legislation designed to protect rural farmers and ranchers. It passed without objection. read more

Washington, DC —The safety of two large international storage dams on the Rio Grande River and the adequacy of emergency plans in the event of failure are at the heart of a lawsuit filed today by Public Employees for Environmental Responsibility (PEER). A federal border agency's refusal to release repair status reports, inundation maps and preparedness plans leaves communities on both sides of the border in the dark about chances of and damage from flooding due to dam and levee breaks. read more
City OKs plan for lake emergency
01-21-11 | dailysentinel.com | by Robbie Goodrich
A 2011 requirement by the Texas Commission on Environmental Quality is making owners of dams file a plan of action should there be a failure in the dam. The Lake Nacogdoches Emergency Action Plan approved earlier this week by the city council delineates procedures necessary to deal with a potential or actual breach of the Lake Nacogdoches dam. The plan outlines contacts and the fan-out of phone calls that would occur in the event there may be a danger or a hazard from dam failure or dam over-topping. Creating the plan was a requirement of TCEQ and had nothing to do with a fear that the Lake Nacogdoches dam might fail. read more
