Ohio River

The Ohio River is a 981-mile-long river in the United States, located at the boundary of the Midwestern and Southern United States, and is the third largest river by discharge volume in the country. It flows through or along the border of six states, and its drainage basin includes parts of 14 states, providing drinking water for five million people. The river was a primary transportation route for pioneers during the westward expansion of the early U.S. and was later canalized in 1929, dividing it into 21 discrete pools or reservoirs by 20 locks and dams for navigation and power generation.learn more on wikipedia
