Calcasieu Lake is located on the Chenier Coastal Plain just east of the Texas-Louisiana border. The Lake receives freshwater input from the Calcasieu River and connects to the Gulf of Mexico through Calcasieu Pass at Cameron, Louisiana.
The basin is characterized by marshes which may be fresh, intermediate, brackish or saline. The basin supports a variety of marine and wetland habitats but is dominated by marshlands. Common living resources include shrimp, Gulf menhaden, nutria, muskrat and waterfowl. Cameron is a major port of call for the offshore oil and gas industry and the area also supports two menhaden processing plants.
