The Plaquemine Lock was completed in 1909 and was designed by Colonel George Goethals, who would later become famous for designing the Panama Canal. When it was completed, the lock was the highest freshwater lock in the world. By 1961, the demand had outgrown the old lock and a new set of locks was opened at Port Allen. The Plaquemine Lock was placed on the national register of historic places in 1972. Now, the area includes the old lock and the Gary James Herbert Memorial Lockhouse, which serves as a museum for the lock.

The site offers general historical and visitors information about the lock. In addition the site offers a list of nearby attractions in Louisiana. Finally, as the site is part of the Louisiana State Park website, the site offers links and information about the entire Louisiana State Park system.
