Tell Us About It!
Plaquemine Lock State Historic Site tells the story of the rich commercial and maritime history of Bayou Plaquemine Lock. Its 52 years of service, 1909-1961, were punctuated with diverse events, ranging from the exportation of Louisiana’s great cypress and oil reserves to the provision of secure connection to the gulf’s Intercoastal Waterway. This man-made inland route assured safe maritime transport throughout World War II. Two original structures remain on-site and are listed with the National Register of Historic Places. Bayou Plaquemine Lock, a 260–foot concrete edifice capped with 55-foot steel gates, allowed for regular commerce between the Gulf of Mexico, the Atchafalaya Basin, and the Mississippi River. The Lock House, constructed of cypress timber and white glazed brick, originally sheltered the machinery necessary for operations of the locks.
What Can We See and Do There?
An exhibit of historic images of Plaquemine Lock and displays about the settlement and commerce of the Atchafalaya Basin are presented throughout the Lock House. A working model demonstrates a barge’s passage through Plaquemine Lock highlighting other historic attractions in the surrounding city. The exhibit Louisiana’s Disappearing Coast shows how much of the coastline has been lost, what caused the losses, and what is being done to restore the coastline. Traditional Louisiana water crafts are also housed on-site in an exhibit dedicated to preserving the unique maritime heritage of Southern Louisiana and the Atchafalaya Basin. Other exhibits include Louisiana Waterways, Historic Boats of the Bayou, Music of the River, and Nautical Stargazing. When scheduling this field trip, teachers should inquire about any special programs that may be included with the regular tour. Teachers may also ask site staff to show a 12-minute video which chronicles the construction, operation, and inevitable closure of Plaquemine Lock.

In class discuss the geography of Louisiana highlighting waterways and major navigational routes. Have students locate Iberville Parish and finger-trace possible water routes out to the Gulf of Mexico. Teachers will receive by mail a packet of information that will include program descriptions upon making field trip reservations.
S-T-R-E-T-C-H-Out Your Field Trip Benefits
Size and scale have new meaning to students after walking through the visitors’ complex at the Plaquemine Lock. Hold class in the school yard or in the gym. Using yardsticks, have students measure out 55 feet and then add 260 feet, the dimensions of the lock edifice and steel gates. This is the total height of the lock. Turn to world maps and have students find other historic lock systems. Ask them to locate the locks on the Tennessee River and the Panama Canal. Teachers can request site staff to visit their classrooms for presentations on Louisiana’s waterways, historic boats of the bayou, and Louisiana’s disappearing coastline.
