Boone Dam Project
In the year since TVA announced the Boone Dam plan, here are some achievements: 288,969 man hours logged at Boone Dam' 390 holes drilled and 372 grouted; 24-hour-a-day operations; 150 workers employed; 24/7 dam safety inspection.
SEPTEMBER 8, 2016—We are on schedule to wrap up the low mobility grouting (LMG) phase of the test grouting project by the end of this month.
How do you gain insight into construction work that takes place hundreds of feet below Boone Dam? A “down-hole high resolution optical televiewer,” a.k.a. high-definition video.
We currently have no plans to raise lake levels beyond the present 1350’-1355’ operating range in the near future.
You asked and we listened—a courtesy dock has been installed at the new Boone Beach and Boat Ramp.
The planting of watershed seedlings is one of the successful “growing” projects initiated at Boone Dam since the repair project was announced nearly a year ago.
A web of 100 piezometers around Boone Dam help engineers understand how the dam is reacting to construction activities.
Once the three new boat ramps were installed this summer and people were able to gain easy access to Boone Lake, we received several requests for courtesy docks. As a result, we’ve installed a new courtesy dock at Pickens Bridge.
Approximately 500 button bush, water hickory and bald cyprus tree seedlings are being planted over the next few weeks in the Boone watershed and around the lake.
The Boone Dam tailrace filter berm is “A-OK” according to TVA divers completing their quarterly underwater inspection the week of August 1, 2016.
When boating near Boone Dam, you may notice a shed with a yellow monitoring—this houses our high-tech robots, which use laser scanning technology to detect the smallest movement in the dam.
It’s been nearly one year since we first shared our plans to repair Boone Dam. During that time, several improvements have been made to allow more people to continue to enjoy the lake, even at its lower levels.
Grout—a concrete-like mixture that is an integral part of the repair of Boone Dam—may seem rather low-tech, but the material’s application to the Boone project is state-of-the-art, requiring constant variations to the recipe to meet some very specific engineering demands.
In addition to the sonic drills already at work at the dam, the project team has recently begun using a new Cubex drill as part of the bedrock grouting process. The Cubex hammers into the bedrock up to 352 feet below the surface, grinding up rock as it drills.
Ongoing work at Boone Dam is attracting national attention from geologists interested in the varied layers and composition soil samples collected during the grout testing.
