JAMESTOWN, Ky. (AP) - Repairs to leaking Wolf Creek dam in southern Kentucky begin a new phase next week.
Contractors will begin drilling more than 275 feet into bedrock to construct a massive concrete wall.
The wall will extend nearly a mile across the earthen part of the dam, which impounds Lake Cumberland.
The Corps of Engineers determined the dam - near Jamestown, Ky. - was at high risk of failure in early 2007. The water was lowered by 43 feet to ease pressure on it.
The Corps warned then that a failure of the dam would flood cities along the Cumberland River in Kentucky and Tennessee and waters could even reach beyond Nashville, Tenn.
Workers have poured grout into the foundation of the dam to help stabilize it.
