The Allegheny River (/ ˌ æ l ɪ ˈ ɡ eɪ n i / AL-ig-AY-nee) is a 325-mile-long (523 km) tributary of the Ohio River that is located in western Pennsylvania and New York in the United States.
This is a list of locks and dams of the Ohio River, which begins at the confluence of the Allegheny and Monongahela rivers at The Point in Pittsburgh, Pennsylvania and ends at the confluence of the Ohio River and the Mississippi River, in Cairo, Illinois. A map and diagram of U.S. Army Corps of Engineers operated locks and dams on the Ohio River.
The Ohio River at Cairo is 281,500 cu ft/s (7,960 m 3 /s); [1] and the Mississippi River at Thebes, Illinois, which is upstream of the confluence, is 208,200 cu ft/s (5,897 m 3 /s). [66] The Ohio River flow is greater than that of the Mississippi River, so hydrologically the Ohio River is the main stream of the river system.
The river is roughly parallel to the border with the state of Ohio, with both Interstate 376 and Pennsylvania Route 18 running parallel to the river itself. The river, which flows throughout the northern half of Beaver County , is the namesake of the county [ 5 ] as well as several locales in both Beaver and Lawrence County.
