File:88c007 Upper entrance bay of Kentucky River Lock No. 3 (26171286134).jpg

English: Looking NNE from upper entrance bay of Lock No. 3

This lock is 145 feet long and 38 feet wide, with about a 13 foot lift. I would guess that the zero point of the gauge at right is the elevation of the upper sill of the lock. Across the river is Cedar Creek Beach, in Owen County.

From Kentucky River Authority:

Lock and Dam 3 were built from 1836-1842 and support a twenty three 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 forty two miles above the mouth of the Ohio River. Lock 3 was shut down in 2007 because of mechanical and structural problems.
