About this map

The Atchafalaya Basin Floodway dominates this landscape, revealing a complex network of waterways and low-lying landforms in Saint Martin Parish. This survey of the lower Atchafalaya basin highlights the intricate drainage patterns where Big Bayou Chene and Little Bayou Chene converge. The terrain is defined by numerous islands and named points, such as Fisher Island and Tiger Island, which stand as landmarks within the marshy environment.

Water serves as the primary structural element here, with wide expanses like Sixmile Lake and Duck Lake connected by a maze of passes and smaller bayous. From Cypress Pass in the west to Riverside Pass in the south, the map details the vital hydrological arteries including Bayou Boutte and Bayou Sorrel that characterize this part of the Louisiana wetlands. The boundary between St. Martin Parish and St. Mary Parish is also clearly delineated as it cuts through the southeastern reach near American Island.
