Long Point Bayou, situated adjacent to the Sabine National Wildlife Refuge and on the west side of Calcasieu Lake between the Gulf of Mexico and Lake Charles, is a vast, open body of water with fragments of eroding marsh.

Heavily impacted by a 2006 oil spill, this area is home to marsh birds, including pelicans, gulls, the endangered black rail, and other waterfowl; a large variety of fish, including red drum and the threatened saltmarsh topminnow; and other coastal wildlife like brown and white shrimp. The area also supports a variety of recreational activities, including fishing.

Construction on the project began in August 2023 to create nearly 400 acres of brackish marsh and tidal using sediment dredged and pumped from the nearby Calcasieu Ship Channel. This material would have to be removed anyway to support transportation and navigation, making this a multi-beneficial, cost- effective project. Other project elements include planting native vegetation into newly restored areas to strengthen them, creating a highly productive transition zone between the interior of the marsh and the intertidal zone.

The Long Point Bayou Marsh Creation project was designed by CPRA in collaboration with the U.S. Environmental Protection Agency (EPA). Engineering and design phase was funded through the CWPPRA program, and construction was funded with $13.7 million in Natural Resource Damage Assessment dollars from the 2006 CITGO oil spill settlement.
