Trip Planner: USA / Louisiana / Plaquemine / Plaquemine Lock
Plaquemine Lock State Historic Site, located in Plaquemine, Louisiana, commemorates an early example of hydraulic engineering design and the historic significance of Bayou Plaquemine, an important navigable waterway that was once a distributary of the Mississippi River. Bayou Plaquemine promoted settlement beginning in the 18th century and helped the area economically by providing an access route between southwestern Louisiana (and thus Texas) and the Mississippi via the Atchafalaya Basin.See Plaquemine Lock and all Plaquemine has to offer by arranging your trip with our Plaquemine trip planner.
The lock itself was designed by Colonel George Washington Goethals of the United States Army Corps of Engineers, who later served as chief engineer of the construction of the Panama Canal Lock, and went on to be the Canal Zone's first governor. Plaquemine Lock was opened on April 9, 1909 after 14 years of construction. When it was built, Plaquemine Lock was the highest freshwater lift of any lock in the world. The lock initially utilized a gravity-flow principle until pumps were installed years later.
The lock was closed after 52 years of service in 1961 due to increased river traffic and the demand for a larger lock, which opened thereafter in Port Allen. The Plaquemine Lock structure was placed on the National Register of Historic Places in 1972. Today, the Gary James Hebert Memorial Lockhouse serves as an on-site museum and visitors center. It is named for the man who led the way to help preserve the Lock site, which today covers 19acre.

Visiting the Plaquemine Lock gives a unique look inside the history of waterways of the Mississippi River. It’s a quick visit....but can make it a full day by also visiting St Louis Plantation...

Great place to walk..also a incredible view when u don't have jerks on dirt bikes trying to run you off the trail
Nice place to stop by and learn about its history. Stanley was willing to spend time and explain things even though it was a little before 5pm (closing time). Highly recommend to stop by and have a look.
