Wicket Dam
A wicket dam, Chanoine wicket movable dam, or barrage à hausse mobile is a movable barrier across the width of a river that is used to hold up water and allow navigation under low-water conditions. When the wickets are lowered during high-water conditions, the river flow is unimpeded. A navigation lock is usually constructed alongside the wicket dam. The wicket dam was invented in the 19th century by , an engineer in the French . Construction of wicket dams primarily occurred in the late 19th and early 20th centuries. William Price Craighill completed the first of the moveable wicket dams built in the United States, after visiting France to study their use. A Chanoine wicket movable dam. was constructed by William Emery Merrill at Davis's Island, 5½ miles below Pittsburgh. From 1875 until the turn of the century, the United States Army Corps of Engineers constructed a series of 53 wicket dams to canalize the Ohio River The Ohio River () is a river in the United States.

Lock (water Navigation)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson (engineering), caisson) that rises and falls.) Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Davis Island (Pennsylvania)
The Davis Island Lock and Dam Site on the Ohio River in Avalon, Pennsylvania, is the site of the former Davis Island lock that was completed in 1885. The lock and dam existed from 1878 to 1922, designed by William Emery Merrill and the U.S. Army Corps of Engineers. The Davis Island Lock and Dam was the first dam that was constructed on the Ohio River. It officially opened on October 7, 1885, with a large dedication ceremony. The Davis Island Dam was the largest Chanoine dam built in the 19th century, and one of the first concrete structures built by the Army Corps of Engineers. It was the first of 51 Chanoine type dams that were built by the Corps of Engineers between 1878 and 1929. The dam was dismantled in 1922, when it was replaced by the Emsworth Locks and Dam less than a mile downstream of the original site. It was listed on the National Register of Historic Places on August 29, 1980 and designated as a National Historic Civil Engineering Landmark by the American Socie ...

United States Army Corps Of Engineers
The United States Army Corps of Engineers (USACE) is the military engineering branch of the United States Army. A direct reporting unit (DRU), it has three primary mission areas: Engineer Regiment, military construction, and civil works. USACE has 37,000 civilian and military personnel, making it one of the world's largest public engineering, design, and construction management agencies. The USACE workforce is approximately 97% civilian, 3% active duty military. The civilian workforce is mainly located in the United States, Europe and in select Middle East office locations. Civilians do not function as active duty military and are not required to be in active war and combat zones; however, volunteer (with pay) opportunities do exist for civilians to do so. The day-to-day activities of the three mission areas are administered by a lieutenant general known as the chief of engineers/commanding general.

Olmsted Locks And Dam
The Olmsted Locks and Dam is a locks and wicket dam on the Ohio River at river mile 964.4. The project is intended to reduce tow and barge delays by replacing the existing older, and frequently congested, locks and dams Number 52 and Number 53. The locks are located about 17 miles upstream from the confluence of the Ohio and Mississippi rivers at Olmsted, Illinois. The Olmsted has been operational since August 2018 while the removal of Locks and Dams 52 and 53 was completed in 2023. The project is both the largest and the most expensive inland waterway project ever undertaken in the United States. History The US Congress, through the Water Resources Development Act of 1988 first approved a $775 million budget for the project in 1988 (October 1987 Price Levels). The lock chambers, completed in 2002, are wide and long. According to the US Army Corps of Engineers, the new dam and locks will reduce passage time to under one hour with the new system. Due to queuing at Lock a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peoria Lock And Dam
The Peoria Lock and Dam is a historic lock and dam complex on the Illinois River at Creve Coeur, Illinois. The complex was built in 1938-39 as part of an effort to make the river navigable and establish a route for barges between Chicago and the Mississippi River. The U.S. Army Corps of Engineers designed the complex; their influence is particularly evident in the dam's control station, as the State of Illinois designed most other dam control stations along the river. The lock has a standard chamber, similar to other locks on the river, and a vertical lift of . The dam is long and includes 108 wicket gates and a Tainter gate; it is one of two Illinois dams that still use wicket gates. The control station is for the most part a large, functional building, though it has Art Deco surrounds at the main entrance. The district also contains an original maneuver boat designed to raise and lower the dam's wicket gates; the boat is still used and is one of four boats of its kind left in ...

La Grange Lock And Dam
LaGrange Lock and Dam is a lock and dam complex on the Illinois River at Versailles, Illinois, Versailles, Illinois. The structure includes a dam and a lock. The U.S. Army Corps of Engineers built the complex from 1936 to 1939; A.F. Griffin designed the lock and dam, while Paul Le Gromwell designed the control station. The lock and dam, as well as a similar lock and dam near Peoria, Illinois, Peoria, were needed when the authorized channel depth was raised to nine foot. The Peoria and LaGrange locks replaced older locks on the lower Illinois River. The lock uses Chanoine wicket gates, which allow for navigation on the river, rather than the Tainter gates seen elsewhere on the river. The structure was added to the National Register of Historic Places on March 10, 2004.
