The andesite line is the most significant regional geologic distinction in the Pacific Ocean basin. It separates the mafic basaltic volcanic rocks of the Central Pacific Basin from the partially submerged continental areas of more felsic andesitic volcanic rock on its margins.
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.

They are located at mile point 606.8, and control a 72.9 miles (117.3 km) long navigation pool. The locks and their associated canal were the first major engineering project on the Ohio River, completed in 1830 as the Louisville and Portland Canal, designed to allow shipping traffic to navigate through the Falls of the Ohio.
