2018 Map of Lake La Graisse

About this map

Lake La Graisse and the surrounding coastal marshlands of Terrebonne Parish dominate this 2018 survey, illustrating a landscape defined almost entirely by its aquatic features. The map details a complex network of coastal waterways where the Gulf of Mexico meets Terrebonne Bay. Prominent hydrological features include the Seabreeze Pass and Bayou Jose in the north, which transition into open waters such as Pass Barre and the Bay Lost Reef. The only named landform, Point Meshe, sits amidst the vast wetlands, highlighting the fragility of the Louisiana coastline in this era. This document provides a precise record of the shoreline and bay systems before further coastal erosion or environmental shifts might alter these southern Louisiana boundaries.
