The Mermentau River (French: Rivière Mermentau) is a 72.3-mile-long (116.4 km) river in southern Louisiana in the United States. It enters the Gulf of Mexico between Calcasieu Lake and Vermilion Bay on the Chenier Coastal Plain.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. Pirate Jean Laffite is rumored to have sailed into the area during the 19th century, possibly stashing gold treasure.Early in the 20th century W. Scott Heywood of Jennings began operating barges on the river to carry oil, which he discovered in 1901, to the railroad. In 1932, Heywood was elected to the Louisiana State Senate from a large district encompassing much of southwestern Louisiana.
