About this map

Grand Chenier sits at the heart of this coastal Louisiana landscape, where the Mermentau River winds through a complex system of marshes and ridges. The map highlights the unique geography of the chenier plain, featuring elevated strands like Little Chenier Ridge, Chenier Perdue Ridge, and Pumpkin Ridge that provide vital high ground amidst the wetlands. These ridges have historically dictated the pattern of settlement and transportation in Cameron Parish, as seen by the narrow roads following the contours of the land.

Water dominates the region, with the river flowing toward Upper Mud Lake and a network of smaller channels including Marseillaise Bayou and Little Chenier Bayou. The inclusion of the Grand Chenier Ferry and specifically named drainage zones like Drainage District Number 2 illustrates the ongoing human effort to navigate and manage this aquatic environment. From Indian Point Island to the many bayous branching off the main river, this survey documents the delicate balance between the Gulf Coast's natural hydrology and the communities built upon its ancient shoreline ridges.
