| 説明 | Construction workers place concrete in the last pile to complete the barrier wall at Wolf Creek Dam in Jamestown, Ky., March 6, 2013. It is the last of 1,197 piles that are approximately four feet in diameter and extend 275 feet into bedrock below the foundation of the 4,000-foot long embankment. The completion makes it possible to begin the process of raising the Lake Cumberland pool level. (USACE photo by Lee Roberts) |
