2012 Map of Grand Bayou du Large

About this map

Caillou Lake dominates the northern reaches of this coastal landscape in Terrebonne Parish, where the complex transition between freshwater bayous and the open Gulf of Mexico is meticulously documented. The map reveals an intricate network of tidal waterways, including Bayou Voisin and Fish Bayou, which define the fragile marshland geography of southern Louisiana. This environment is not only a natural interface of land and sea but also a site of industrial activity, evidenced by the Pass Des Ilettes Gas Field located in the southeastern quadrant. The lack of traditional roads or terrestrial settlements underscores the importance of waterborne navigation and the energy economy in this specific region of the Gulf coastline during the early 21st century, providing a clear record of the shoreline and maritime infrastructure near Turtle Bayou before further coastal changes.
