Created in 1937, Lacassine National Wildlife Refuge was the 123rd refuge established within the National Wildlife Refuge System.

Lacassine National Wildlife Refuge is located at the edge of Grand Lake and 15 miles from the Gulf of Mexico in Cameron and Evangeline Parishes in Louisiana. The refuge is strategically located on the boundary of coastal marsh and agricultural habitats, as well as at the southern terminus of the Mississippi and Central Flyways, making the refuge critically important to migratory birds, especially wintering waterfowl.

Most of the 34,724-acre refuge consists of freshwater marsh with only a few natural ridges and levees. The dominant feature of the refuge is Lacassine Pool, created by enclosing a 16,000-acre marsh with a low levee. The refuge is bisected from east to west by the Gulf Intracoastal Waterway and north to south by Lacassine Bayou. Lacassine Refuge provides valuable habitat for resident and migratory birds, mammals, rodents, reptiles, and other wildlife. Lacassine Pool serves as a sanctuary for wintering waterfowl with a large concentration of birds using the area to feed and rest.
