About this map

The Atchafalaya Basin Floodway dominates this portion of Saint Martin Parish, revealing an intricate labyrinth of wetlands where water and land are in constant flux. The landscape is defined by a rhythmic system of bayous named for the months of the year, including Bayou February, Bayou April, and Bayou May. These seasonal identifiers underscore the temporal nature of the basin's hydrology. Centrally located, Duck Lake and Duck Lake Pass serve as primary hydraulic conduits through the dense swamp, surrounded by named landforms like Fisher Island and Tiger Island.

Deep in the basin, the convergence of Little Bayou Long and Big Bayou Chene illustrates the complex drainage patterns required for flood management. To the south, Sixmile Lake and Riverside Pass mark the transition toward more open water, while features like Gray Horse Isle and American Island provide fixed points of reference for navigators and researchers studying the shifting geography of the Louisiana coast.
