Boone Dam Repairs, That Are Set To Be Completed In July 2020, Appear To Be On Schedule. However, TVA Officials Say Don’t Look For Lake Levels To Return Back To Normal Right Away. A Refill Plan For The Lake Will Be Provided After Repairs Are Completed. The Update Was Delivered During An Annual Environmental Conference In Kingsport. Grouting Is Complete And Construction Of Upstream And Downstream Rock Berms On Top Of The Dam Are Ongoing To Further Stabilize It So It Can Support Heavy Equipment During The Construction Of The Concrete Diaphragm Wall. The Cost Of The Project Is Expected To Surpass 305 Million Dollars.
