About this map

Lower Atchafalaya River dominates this wetland landscape southwest of Morgan City, where the complex hydrology of the Atchafalaya Basin meets the coastal marsh. The map depicts a labyrinthine network of waterways, from major arteries like the Avoca Island Cutoff and Bayou Shaffer to smaller channels such as Haney Bayou and Halfway Bayou. These watercourses define the boundaries and accessibility of landmasses like Bateman Island and Honey Island.

The interaction between man-made infrastructure and the natural environment is evident along Levee Rd, which provides a rare terrestrial path through the wetlands. Navigation and drainage features like the Burke Canal and Lower Pass illustrate the engineering required to manage this low-lying terrain. Scattered lakes, including Sweetbay Lake and Lake Gascha, punctuate the marshy landscape near landmarks such as Sword Point and East Bend, highlighting the intricate coastal geography of Terrebonne and St. Mary Parishes.
