Bristol Herald Courier, Jan 14, 2015 (emphasis added): Water is still seeping at Boone Dam and the cause has yet to be determined… Boone Dam has two portions, a concrete portion [and] an earthen embankment. “The leak is actually in the embankment, that’s where all the focus is,” Travis Brickey, a spokesman for TVA, said Monday… TVA is currently drilling around the area where the units discharge water… Though there is no clear timeline on how long the investigation will take, Brickey said that it’s safe to say that there will be a project at the dam. But he’s not sure… how long the project will last or how it will impact the reservoir.

WJHL, Jan 12, 2015: TVA… says it plans to make an announcement about… water seeping out of a nearby riverbank near Boone Dam [after] what’s now being

    described as a “prolonged analysis” to find the source of the water moving underground… [TVA spokesman Travis Brickey] confirmed TVA engineers now suspect water is moving through fissures in rock under the earth-filled section of Boone Dam… TVA has lowered Boone Lake [to reduce] pressure on the dam [and] stopped passing water through its power-generating turbines at Boone Dam as a safety precaution… That’s forced TVA to release water [which is] shooting into the air… a highly visible water release that seems to have fired speculation about what’s going on at Boone Dam… TVA is non-committal about its plans to refill the lake in the spring. “It’s too soon to tell,” Brickey said.

    TVA spokesman Travis Brickey, Jan 12, 2015: “We are considering all possibilities and continue to analyze the data… We’ve installed additional monitoring equipment along with an extensive core drilling campaign… We’re aware that there are plenty of rumors… Our engineers are working to develop next steps.”

    More from Brickey: “We’re doing a lot of engineering work and looking at repair options and what that might entail… I assure you there are a lot of people working on this.”

    WCYB, Dec 29. 2014: People who visit Boone Lake won’t be seeing normal water levels any time soon… Brickey says that TVA is reviewing repair options on Boone Dam… But, the longer it takes for TVA to announce the plans, the more concerned many marina owners are becoming.

    Kingsport Times-News, Dec 29, 2014:“It’s all speculation,” Brickey said of rumors that the lake’s drawdown could last two years or longer… TVA’s most recent press [said] “reservoir levels could be lowered further if conditions change… The duration of the drawdown will depend on the results of the ongoing analysis.”

ENENEWS: BOONE DAM STABILITY ISSUES

Sinkhole develops under dam in US — 7 nuclear reactors downstream — Water now seeping out — Gov’t notified of ‘stability issues’, plants begin evaluating potential flood impacts — Official: An ‘uncommon’ occurrence, we’re monitoring it continuously and working around clock — Structure same height as Niagra Falls (PHOTOS)

Johnson City Press, Oct. 30, 2014 (emphasis added): Oct. 20 inspection of [Tennessee’s Boone] dam revealed a sink hole… Six days later, an uncommon occurrence happened when seepage was found near the location of the sink hole at the base of the dam…

TN Dam Nuclear

NRC, Oct. 30, 2014: … BOONE DAM STABILITY ISSUES… “TVA conducted a briefing for government officials… after discovery of a sink hole near the base… water and sediment [has been] found seeping from the river below the dam. TVA is continuously monitoring the dam… The dam is located upstream of all three TVA nuclear sites… The NRC Senior Resident Inspector was notified. The licensee is evaluating this event for potential impact on the design basis flooding level.”

Times Free Press, Oct. 30, 2014: Tennessee Valley Authority engineers [will] search for the source of water seepage… Water and sediment were found Sunday seeping from the river bank below the dam.

TVA, Oct. 30, 2014: A sink hole was discovered near the base… water and sediment was found seeping from the river bank below the dam…

 

 

John McCormick, VP at TVA: [We’re] exercising an abundance of caution… Unless it’s a huge storm, we can do what we need… we are continuously monitoring the dam… engineers want to be sure we understand what caused the sink hole and where the water and sediment is coming from.

WCYB, Oct. 30, 2014: [A] sinkhole and seepage of clay particulates into the water at Boone dam… [is near] the bottom of structure on the river side of the dam… TVA employees are working around the clock to find the cause of the sinkhole and the source of the seepage. “The seepage into the waterway is not a common occurrence,” said McCormick… they do not have a definite timetable for finding the source of the seepage…

Boone Dam is just over the border from Virginia, where a powerful M5.9 quake struck in 2011 — Times Free Press: TVA inspects dams, nuclear plants after earthquake [and] is in the process of performing visual walk downs and inspections at… Boone

USGS: [Quakes] in the eastern U.S. can travel much farther and cause damage over larger areas than previously thought [and] damaging effects can extend over a much larger area… the farthest landslide from the 2011 Virginia earthquake was 245 km from the epicenter. This is by far the greatest landslide distance recorded from any other earthquake of similar magnitude… [This quake] occurred in an area 20 times larger than expected [and] landslide distances… are remarkable… [it’s] the largest distance limit ever recorded…
