For example, the Bollène lock on the River Rhône has a fall of at least 23 m (75 ft), the Leerstetten, Eckersmühlen and Hilpoltstein locks on the Rhine–Main–Danube Canal have a fall of 24.67 m (80.9 ft), each and the Oskemen Lock on the Irtysh River in Kazakhstan has a drop of 42 m (138 ft).

The Weitzel Lock, was built between 1873 and 1881 directly south of the State Lock, and was the first lock to be operated by the federal government. At 515 ft (157 m) long, 80 ft (24 m) wide, and 17 ft (5.2 m) deep, it was the longest lock in the world upon its completion.
The locks and weirs, in effect, break the river up into 44 lakes or lock reaches. Each lock controls the reach above it and thus identifies it. Each reach has its own character and points of interest. Many reaches host regattas and other events and these are coordinated through a River User’s Group for the reach. [6]
Prior to the installment of the locks and dams, the river was sometimes so shallow that people could wade across it. Skip to main content. 24/7 Help. For premium support please call: ...
Some locks have more than one chamber, often of different dimensions. These locks provide the essential infrastructure that allows tows to "stair-step" their way through the system and reach distant inland ports such as Minneapolis, Chicago, and Pittsburgh. The locks can generally be categorized by three different sizes, as expressed by length.
A river is thereby converted into a succession of fairly level reaches rising in steps up-stream, providing still-water navigation comparable to a canal; but it differs from a canal in the introduction of weirs for keeping up the water-level, in the provision for the regular discharge of the river at the weirs, and in the two sills of the locks ...
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 locks could raise a vessel 14' at high water and 24' at low water. [3] The lock gates were 56 feet (17 m) wide and 90 feet (27 m) high. The locks were carefully designed to address the great variation in the height of the river, the difference between high and low water being 55 feet (17 m).
