About this map

Lower Atchafalaya River and a dense network of coastal distributaries dominate this corner of Terrebonne Parish and St. Mary Parish. The landscape is defined by the hydrologic engineering of the Avoca Island Cutoff and the accompanying Levee Rd, which provides a terrestrial boundary between the river system and the expansive wetlands to the east. Navigable waterways like Bayou Shaffer and Bayou Penchant snake through the marsh, connecting named landforms such as Bateman Island and Honey Island. The intricate web of smaller channels, including Blackbird Bayou and Little Horn Bayou, reflects the dynamic nature of the Mississippi River Delta's southern reaches. This survey captures the region's character as a specialized environment where human infrastructure, represented by the Burke Canal, meets the natural hydrology of Sweetbay Lake and Lake Gascha.
