Grande Ecaille and the surrounding marshlands of Plaquemines Parish appear in this coastal survey, highlighting the complex relationship between Louisiana's wetlands and its energy infrastructure. The southern portion of the map is dominated by the Lake Washington Oil and Gas Field, showing a dense network of canals and industrial footprints in an area defined by water. North of Lake Grand Ecaille, the landscape dissolves into a labyrinth of waterways including Bay Batiste, Rattlesnake Bayou, and Lost Bayou. Large-scale man-made features like the Robinson Canal and Socola Canal Number Two cut through the natural drainage, illustrating the significant engineering required to navigate and utilize these tidal basins. The map provides a detailed view of these fragile landforms, from Big Island in the west to the winding course of Two Sisters Bayou in the northeast.
