Ohio River Canalization
In 1929, the Corps of Engineers completed the Ohio River Canalization. The project began in 1875 in an effort to tame the turbulent waters of the Monongahela, Allegheny, and Ohio rivers. Utilizing a system of dams and locks, the Ohio River Canalization turned the unruly rivers into a 967-mile chain of waterways that stretches from Pittsburgh, Pennsylvania, to Cairo, Illinois.
