The Leland Bowman Lock System was set up along the Intracoastal Waterway in the early 1950’s, before being redesigned in 1985, which is the new lock system you see here.
At 110 feet wide and 1210 feet long, the Leland Bowman Lock is the biggest lock system in Louisiana. Allowing them to pass some of largest barges hauling mainly chemicals, oil, rice, gravel and sand. And the operators see plenty of traffic.
The main purpose of the lock system is to keep the inland waters free of salt so farmers can continue to use the water for their various agricultural reasons.
To Vermillion Parish, these locks play a vital role in the lives of those to rely on the fresh water supply.
