BLOUNTVILLE, Tenn. (AP) - The level of Boone Lake in eastern Tennessee will fall 14 feet below its normal winter low point as the Tennessee Valley Authority replaces the heavy chains and cables used to control Boone Dam's gate system.

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.

TVA Vice President of River Operations John McCormick told The Johnson City Press the agency doesn't quite know what will happen with the shoreline and some of the marinas because of the drop.

An inspection showed the need to replace the 60-year-old chains.
