Lock (water transport)
A lock is a device for raising and lowering boats between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is...

. The project was approved on January 27, 1960 by the Secretary of the Army under authority of Section 6 of the Rivers and Harbors Act, approved March 3, 1909, to replace the existing Locks 43, 44 and 45.

Dam

The Cannelton Dam has two sections. The main section is 1412 feet (430.4 m) long with twelve tainter gate

s. The gates are held between 15 feet (4.6 m) piers. Each gate is 42 feet (12.8 m) high and 100 feet (30.5 m) long. Electric hoists on top of the piers are used to raise or lower the gates. At the end of the gated section of the dam there is second section, a concrete fixed weir

 on the Ketucky side of the river. The weir is 195 feet (59.4 m) long.

Locks

The Cannelton Locks run parallel to each other on the Indiana side of the river. There are two locks alongside the dam, the main lock which measures 110 feet (33.5 m) by 1200 feet (365.8 m) and the auxiliary lock that is 110 feet (33.5 m) by 600 feet (182.9 m). The locks can be filled or emptied in around 8 minutes.

The upper pool is normally at an elevation of 383 feet (116.7 m), mean sea level and the lower pool elevation is 358 feet (109.1 m), mean sea level. The lift (difference) between the two pool is 25 feet (7.6 m).
25 million USgals (94,635.3 m³) of water is required to operate the lock.

The locks reduce travel time because it enables large commercial tows to go through only one lockage rather than the three locks it replaced. Also the large lock chamber allows a large vessels to pass through the lock in a single operation instead of using smaller lock sections.

Construction

The construction of the locks began in July 1963. The locks began operation in December 1966 and were completed April 1967. Construction on the dam started in August 1965 and the dam was completed in 1974. The structure was designed, built, and is operated by the United States Army Corps of Engineers
