About this map

The Lower Atchafalaya River winds through this coastal Louisiana landscape, defining the character of Patterson and the surrounding riverfront communities. This region is a complex web of hydraulic engineering and natural waterways, where the Atchafalaya Basin Floodway and a series of massive levees, such as the W Atchafalaya Basin Floodway Levee, manage the flow of water around human settlements. The map illustrates a dense concentration of infrastructure along the river bends, including the Harry P Williams Memorial Airport and the junction of Bayou Teche.

Beyond the residential corridors of Bayou Vista and Berwick, the land gives way to an intricate system of bayous and islands. Waterways like Bethel Bayou, Oaks Bayou, and the Intracoastal Waterway reveal the essential role of water navigation in St. Mary Parish. Named features such as Possum Point and Morgan Island anchor a landscape dominated by wetlands and the persistent threat of seasonal flooding.
