This marsh creation project is in the Barataria Basin within a ribbon of wetlands stretching from the Mississippi River levee to the community of Lafitte known as the Barataria Landbridge. Historically, only a limited hydrological connection existed between the fresher upper basin and the saltier lower basin. Canals, erosion and subsidence have led to significant land loss in this area, exposing freshwater wetlands to saltwater intrusion and increased wave energy.

This project will create marsh within a footprint of approximately 15,000 acres in western portion of the marsh with the goal of creating new wetland habitat, restoring degraded marsh, and reducing wave erosion.

This undertaking supports a diverse ecosystem, fostering the well-being of various fish and marine wildlife. Notably, it ranks among the largest dredging projects ever undertaken in Louisiana. The land formed as a result of this project will play a crucial role in mitigating tidal flooding in nearby communities like the town of Jean Lafitte and enhancing storm surge protection in the densely populated New Orleans area.

This restoration project will also help protect the National Park Service’s Jean Lafitte Barataria Preserve, which encompasses 23,000 acres of swamps, marsh and waterways and is home to a variety of birds and other wildlife that use the park’s waterways and wetlands for foraging, resting and nesting habitat.
