2015 Map of Big Constance Lake

About this map

Gulf of Mexico tides meet the coastal marshes of Cameron Parish in this 2015 survey of the southwestern Louisiana shoreline. The landscape is defined almost entirely by its aquatic features, where Big Constance Lake and its smaller counterpart, Little Constance Lake, serve as focal points for a network of winding waterways. These include Constance Bayou, Little Constance Bayou, and Dyson Bayou, which snake through the low-lying terrain before reaching the open gulf. This map provides a clear record of the coastline's configuration in the early 21st century, illustrating the transition from open water to the interior marsh system. For those interested in the environmental history of the Chenier Plain, this data captures the specific hydrological layout of a region where the boundary between land and water is constantly shifting.
