Plaquemine Lock State Historic Site

As a distributary of the Mississippi River and a route to the heartland of Louisiana through the Atchafalaya Basin, Bayou Plaquemine was used as a navigable artery centuries before the age of European exploration. From the early 1700s, Bayou Plaquemine served as a commercial transport route, promoting settlement and economic prosperity in southwest and northern Louisiana via the Atchafalaya, Red and other rivers.
