2018 Map of Patterson

About this map

The settlement of Patterson and its neighboring communities are defined by a complex labyrinth of waterways and engineering in St. Mary Parish. The landscape is a study in flood management and transit, dominated by the massive Atchafalaya Basin Floodway and the protective W Atchafalaya Basin Floodway Levee. Residents and industry are concentrated along the banks of Bayou Teche, where towns like Avalon and Calumet sit between the bayou and the northern levee systems. To the south, the terrain dissolves into the marshy expanse of the Intracoastal Waterway and the Lower Atchafalaya River, threaded by countless smaller channels like Little Bethel Bayou and Double Mouth Bayou. Infrastructure such as the Harry P Williams Memorial Airport and the BNSF Railway provides critical links across this watery geography, connecting isolated landings like Wilsons Landing to the regional economy.
