No safety concerns for area dams, Corps announces
NASHVILLE, TENN. — There are no current safety concerns for area dams despite heavy rainfall throughout the region, the U.S. Army Corps of Engineers announced today.
“We are seeing no problems with the integrity of our dams despite record rainfall amounts throughout the region,” stated Barney Davis, Chief of Engineering and Construction for the Corps’ Nashville District.
The Corps is continuing 24/7 monitoring at two high priority dams, Wolf Creek Dam in Jamestown, Ky. and Center Hill Dam in Lancaster, Tenn. “The data from these projects is showing nothing of concern,” continued Davis. “We will continue monitoring these projects closely until the lakes return to their lowered target elevations.”
While the lake elevations at both dams are higher due to this weekend’s rainfall, there is no impact on the stability of the dams. Because of this, the Corps will continue to operate the dams to reduce flood damages downstream. Neither lake is currently at the elevation reached in February 2010.
The Nashville District has moved to daily instrumentation reading and inspection at J. Percy Priest Dam in Nashville and Old Hickory Dam in Hendersonville, Tenn. Data and observations show that both dams are structurally safe.
“We have no structural concerns at any of our dams, but we will continue to monitor them closely throughout this situation,” stressed Davis.
Fly ash being used to help stabilize Wolf Creek Dam
Somerset Commonwealth Journal - Limestone fly ash being shipped at the rate of 100 tons a week through Somerset Rail Park in Ferguson is utilized as a stabilizing component during rehabilitation of Wolf Creek Dam.
Allison Jarrett, public affairs specialist for the U.S. Army Corps of Engineers’ Nashville District, said fly ash is an additive mixed in concrete being used to construct a barrier wall in the dam. The ash also stabilizes watery slurry from drilling that is discarded in a disposal area.
Wolf Creek Dam, plagued with uncontrolled seepage, is undergoing a $584 million rehabilitation currently scheduled for completion in December 2012. A barrier wall extending up to 100 feet into bedrock below the dam is touted as a permanent fix for the 59-year-old structure that impounds Lake Cumberland.
Pyles Concrete Inc., of Columbia, built a new concrete plant on U.S. 27 near the entrance to Lake Cumberland State Park to supply concrete for the dam rehabilitation. A company official said the dam repair project will take 350,000 cubic yards, or 1,155,000,000 pounds of concrete. That is enough concrete to build a 5-foot-wide sidewalk from the dam in Russell County to Washington, D.C.
Fly ash is a generic term for fine residue removed from stack gasses using various types of air quality control equipment The ash being shipped through Somerset is a byproduct of electrical generation plants in Florida and is being obtained from L.A. Ash Inc., based in Sulphur, La. Jimmy Smith, sales representative for L.A. Ash, says his company has a contract to remove ash from the generating plants.
