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.

[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.

Amid concerns of algal blooms, the Ohio EPA reported Tuesday that 86% of the state's major rivers are meeting water quality standards.
The plant is located inside the Ohio Natural Wildlife Conservation Area and is considered a large impoundment hydro power plant. [3] The station was built after a canal and dam within the Ohio river in an attempt to allow boats to navigate the 8 ft vertical drop among the falls that spanned 2 miles wide. Production of the canal and dam began in ...
The Louisville and Portland Canal was a 1.9-mile (3.1 km) [1] canal bypassing the Falls of the Ohio River at Louisville, Kentucky.The Falls form the only barrier to navigation between the origin of the Ohio at Pittsburgh and the port of New Orleans near the Gulf of Mexico; circumventing them was long a goal for Pennsylvanian and Cincinnatian merchants.
