2024 Map of Grosse Tete SW

About this map

The Atchafalaya Basin Floodway dominates this landscape, a vital component of the lower Mississippi River's flood control infrastructure. This modern survey illustrates the complex hydrography of the Iberville Parish swamplands, where natural waterways like Bayou Maringouin and Bayou Grosse Tete weave through a network of managed water systems. The map captures the specialized transit patterns of the basin, showing local routes such as Bayou Blue Rd and Mcbay Rd that skirt the edges of the wetland interior. Notable water bodies including Halfway Lake and the engineered Trinity Canal reflect the region's historical and ongoing efforts to balance natural water flow with human utility. In the southern reaches, the Upper Flat and the confluence of Bayou Lafayette with Bayou Blue provide a detailed view of the basin's drainage patterns and the persistent watery character of this Louisiana interior.
