TVA making improvements to East TN dams

(WBIR) TVA is working on several projects to help make some of East Tennessee's dams stronger for years to come.

Crews are inserting new anchors, or massive bolts, into the Cherokee and Douglas dams. The massive bolts will be drilled through the dam into the rock below.

The project is expected to be finished in December.

TVA officials say dam upgrades are necessary from time to time as disaster predictions change and knowledge about dam safety improves.

"The reason we do this is because requirements for the analysis, the seismic input, the height of the floods change over time, precipitation, changes as our knowledge becomes larger. So we're making the dams stronger for future generations," said John Kammeyer, TVA vice president of civil projects.

Crews also are working to replace temporary barriers meant to add height to four East Tennessee dams, including Cherokee. Those projects will lead to some adjustments at TVA recreation areas and parking lots. Signs in those areas will alert visitors to the changes.
