2020 Map of Pass a Loutre East

About this map

The Pass a Loutre waterway system dominates this aquatic landscape in Plaquemines Parish, where the Mississippi River delta meets the Gulf of Mexico. This survey illustrates the intricate network of distributaries and bays that characterize the outer reaches of the Birdfoot Delta. Notable coastal features like Lighthouse Bayou and Customhouse Bay point to a history of maritime navigation and customs enforcement at this critical river mouth. The terrain is defined by shifting sediments, evidenced by unique geological formations such as the North Mud Lumps and Thomasin Lumps. Navigation channels like North Pass, Southeast Pass, and Northeast Pass slice through the wetlands, creating a complex patchwork of marsh and open water. Between these active passes lie shallow basins such as Blind Bay and Bull Bay, demonstrating the active deltaic processes of land loss and accretion that continue to reshape the Louisiana coastline.
