About this map

The Amite River Diversion Canal dominates this low-lying swamp landscape, illustrating the mid-20th-century hydrological engineering effort to redirect water flow across several parish lines. At this time, the area served as a complex intersection of natural and man-made waterways, where the Blind River and Petite Amite River snake through a labyrinth of bayous and wetlands. An Old Railroad Grade indicates earlier industrial or logging activity that once penetrated these marshes.

Water management is the defining characteristic of this terrain, evidenced by the New River Canal and Bourgeois Canal. The map records the precise convergence of four parishes — Livingston, Ascension, St. James, and St. John the Baptist — near features like Alligator Island. This specific survey preserves the naming conventions of smaller waterways such as Bayou Secret and Bayou Fusil before further development or ecological shifts altered the character of the basin.
