2018 Map of Bay L'Ours

About this map

Bay L'Ours dominates this coastal landscape where the low-lying wetlands of Southeast Louisiana meet the open waters of the Gulf interior. The map illustrates a complex network of waterways, primarily the meandering Bayou de la Gauche and the wide expanse of Bayou Perot. These natural channels are contrasted by the straight-line engineering of the Harvey Cutoff, reflecting the region's reliance on managed water routes for navigation and local industry. The boundary between Jefferson Parish and Lafourche Parish snakes through the center of the sheet, following historical watercourses that define local jurisdiction. This 2018 survey captures the intricate transition between marshland and open bay, documenting the specific shoreline of Turtle Bay and the surrounding township and range divisions during a period of ongoing coastal change.
