Lock and Dam 2

Lock and Dam 2 were built from 1836-1842 and support an eleven mile long pool of water. The original dam was a timber crib structure, consisting of an outside frame of timbers filled with dirt and rock, and the original lock was stone masonry. The structures are located thirty one miles above the mouth of the Ohio River. The lock was shut down in 2007 because of structural and mechanical problems.
