The Mermentau River is located in Southern Louisiana and flows between Calcasieu Lake and Vermillion Bay on the Chenier Coastal Plain of Texas and Louisiana.
The Mermentau River supplies freshwater for the Mermentau Basin. The Chenier Basin is located between the Mermentau Basin and the Gulf of Mexico, and is unique in that it no longer contains any true estuarine Gulf habitat although historically the basin served as a productive estuarine nursery ground. Freshwater inflow is from the Catfish Point control structure. Presently, several large freshwater lakes (Grand Lake, White Lake) and confined wetlands dominate the region. These habitats are confined within the mainland and isolated from the influence of saltwater by a series of water control structures or 'locks'.
A significant percentage of the basin lands are publicly owned as Federal refuges and State wildlife management areas.
