Boone Lake will drop 14 feet below its normal winter low point this year to allow Tennessee Valley Authority workers to replace the heavy chains and cables used to control Boone Dam’s gate system, and the agency’s officials are warning boaters and resident to use caution.
For the first time since the dam was built in 1953, the 280-feet-long intake gate chains and the spillway gate cables will be removed and replaced, which means TVA needs to put the Boone Reservoir in a deep drawdown to be able to access.
“Because we’re doing a deep drawdown, we don’t really know what’s going to happen with some of the shoreline and some of the marinas,” TVA Vice President of River Operations John McCormick said Thursday at a media conference. “We want to make sure we give an opportunity for the folks around here to get there boats and equipment out of the water, so they aren’t damaged, and also to give them the opportunity to do shoreline or dock work.”
