2025 Map of Pass a Loutre East

About this map

Pass a Loutre and the surrounding distributaries of the Mississippi River delta dominate this coastal landscape, illustrating the fragile, shifting landforms where the river meets the Gulf of America. Named waterways like Tommy Dantz Bayou, Lonesome Bayou, and Jackson Bayou snake through the marsh, revealing the complex hydrography of Plaquemines Parish. Distinctive geological features, such as the North Mud Lumps and Thomasin Lumps, rise near the mouth of the passes, while areas like Customhouse Bay and Lighthouse Bayou hint at the historical navigational and maritime significance of these outer reaches. The presence of Middle Ground and various bays, including Bull Bay and Jackass Bay, underscores the constant interplay of sediment and sea that defines this ever-changing southern Louisiana coastline.
