Boone Dam Project
Auger drills, sampling and testing sensors evaluate the effectiveness of Boone Dam repairs to date, as subtle changes to replair schedule are made to optimize construction activity.
Inclinometers Installed to Evaluate Grouting Work
The Boone Dam project will be installing additional sensors and conducting exploratory drilling on the earthen embankment. The information obtained will give us a clearer view of the geology under the embankment and help us further refine our repair plan.
The “grout gator” is an all-terrain vehicle that serves as a centralized location to direct the injection of the grout in order to reach desired flow rates and pressures.
Dam safety efforts include diving to ensure the stability of the dam's filter berm, and routine inspection of the sluice gate and sluice tunnel, which occurs every five years.
Workers at Boone Dam are immersed in the high mobility grouting phase of the project.
Even with the dry weather, TVA’s River Management team was able to successfully raise and lower Boone Lake late last month to test the effectiveness of early project grouting work.
TVA biologists are confirming what most anglers already know—Boone Lake remains a great fishing place.
Lake levels will fluctuate to assist in testing; high mobility grouting will continue; exploration on the right rim will begin.
OCTOBER 7, 2016—With the planned November effectiveness testing of the low mobility grouting work, we are already looking forward to the next phase of the project: high mobility grouting (HMG) testing.
OCTOBER 3, 2016—Local residents and businesses will get to see visible evidence of progress on the Boone Dam Repair this fall as lake levels will be temporarily lowered and raised to test the effectiveness of grout installed over the past several months.
OCTOBER 7, 2016—We continue to receive questions about the vegetation that has grown on the exposed banks of Boone Lake during the lower water levels. Although some consider it a problem, the vegetation is actually doing two positive things.
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.
