Boone Dam project update: lake levels fluctuate for 'baseline measurements'

People living near Boone Lake may notice changes in lake levels in the coming months as construction of the Boone Dam project continues. 

Tennessee Valley Authority spokeswoman Mary Ellen Miller announced Tuesday that lake level fluctuations will be taking place until March to provide Boone Dam engineers the opportunity to “take baseline measurements prior to the construction of the wall over the next two years.” 

“Today we’re at 1,354, and we will continue a slow raise up until February when we will be at 1,358 feet — about 3 feet outside of normal operating range,” she said Tuesday. 

The additional grouting and drilling are “moving toward completion,” and Miller said contractors for the cutoff wall are in daily meetings with TVA officials as workers continue to put the necessary infrastructure in place for the wall’s construction. This phase of the project should begin in the summer. 

Before the main construction phases of the cutoff wall begins, Miller said the levels will and must remain between 1,350 and 1,355 feet in the spring as more infrastructural work continues. 

After the construction of the cutoff wall is complete in 2021, TVA officials will move forward with crest and site reclamation and then reservoir testing. During that time, lake levels will fluctuate again. 

“We’re moving right along and progressing nicely,” Miller said, adding that the $450 million project is still projected to be completed by 2022.
