2020 Map of Bay Batiste

About this map

Grande Ecaille and the surrounding marshlands of Plaquemines Parish appear here as a complex network of coastal waterways and industrial interventions. This 2020 map documents the modern footprint of the southern Louisiana wetlands, where natural features like Bay Batiste and Lake Grand Ecaille meet the straight-line cuts of the Freeport Sulphur Company Canal and Socola Canal Number Two. The map illustrates the fragile geometry of the coastline, featuring prominent landforms such as Big Island and the meandering paths of Two Sisters Bayou and Lost Bayou. For those studying the environmental and industrial history of the Mississippi River delta, this survey provides a clear view of how water management and resource extraction have shaped the contemporary landscape, including the connections between Barataria Bay and the interior marsh.
