About this map

Atchafalaya Basin Floodway dominates this coastal Louisiana landscape, revealing a complex network of waterways where Iberia Parish and St. Martin Parish meet. The terrain is a labyrinth of interconnected channels including Grand Bayou and the oddly named Four Hundred Dollar Bayou, which snake through the wetlands toward the open waters of Lake Fausse Pointe. This modern survey documents the precarious balance of the Mississippi River's spillway system, centered on the eponymous Jackass Bay.

Cultural markings are sparse in this saturated environment, limited to the isolated settlement at Fish Island and the elevated Levee Rd that provides a singular land route through the swamp. Key navigational markers like Eagle Point and Mestayer Point define the northern shoreline of the lake, while numerous smaller water bodies such as Cochon Bay and Petit Lac highlight the shifting, water-dominant geography of the lower Atchafalaya basin.
