About this map

The Atchafalaya Basin Floodway dominates this landscape, a complex labyrinth of waterways at the intersection of Iberia, St. Martin, and Assumption parishes. The terrain is defined by an intricate network of moving water, where the massive Gulf Intracoastal Waterway cuts a straight industrial line through the natural meandering of the Old River and Bayou Postillion. This environment is a classic example of the Louisiana basin's hydrology, where major arteries like Bayou Long are supported by distinct branches such as Middle Fork Bayou Long and West Fork Bayou Long. The cartography reveals how water management and natural drainage systems coexist in this wetland interior, showing the specific paths of smaller streams like Bayou Catonia and Little Bayou Mallet as they feed into the larger basin system.
