2012 Map of Morgan City SW

About this map

Lower Atchafalaya River currents and intricate wetland hydrology dominate this 2012 survey of southwestern Terrebonne Parish. The landscape is a labyrinth of natural and engineered waterways, where the Avoca Island Cutoff and Bayou Shaffer facilitate industrial and waterborne transit through the marsh. This era of the region’s development is characterized by the presence of the Sweetbay Lake Oil and Gas Field and a complex levee system, including Levee Rd, protecting the low-lying terrain from the surrounding basin waters. Smaller features like Lake Gascha and the distinctively named Sword Point and East Bend provide essential reference points for navigating the shifting alluvial environment. Numerous smaller bayous, such as Big Horn Bayou and Little Horn Bayou, illustrate the secondary drainage patterns that define the local topography south of Morgan City.
