East Bayou Lafourche Marsh Creation

The East Bayou Lafourche Marsh Creation project is a Barataria Basin project in the 2023 Coastal Master Plan that will establish more than 33,000 acres of wetland habitat on the eastern side of Bayou Lafourche, along the scenic Caminada Headland. This project will serve multiple essential purposes, including the development of fresh wetland ecosystems, the rehabilitation of deteriorated marshlands and the mitigation of wave erosion.

This project will help to replenish the devastated region still recovering from the impact of Hurricane Ida, which made landfall in 2021 at nearby Port Fourchon with storm surge as high as 14 feet and winds at a sustained speed of 140 mph. The regenerated marshland will play a pivotal role in safeguarding the area against potential storm surge, wave energy and flooding.

Marsh creation projects like this use sediment from the Mississippi River, nearby water bottoms or offshore shoals to build land in shallow open-water areas, typically where land has been lost. The East Bayou Lafourche Marsh Creation Project is located in both Lafourche and Jefferson Parishes, near Port Fourchon, the Caminada Headland and Grand Isle.

Benefits of Large-scale Marsh Creation projects

• Habitat restoration: The creation of marshland provides a restored and improved habitat for aquatic, terrestrial and avian wildlife. Thousands of species depend on marshes for breeding, feeding and shelter.
• Fisheries support: Healthy marsh ecosystems play a crucial role in supporting fisheries. The restoration project can enhance the availability of food sources and breeding grounds for fish, contributing to the overall health and sustainability of local fisheries.
• Water quality improvement: Marshes act as natural filters, helping to improve water quality by trapping sediments and filtering pollutants. This benefits our seafood industry and ensures a healthier environment for all life in and around the marsh.
• Carbon sequestration: Marsh vegetation is effective in sequestering carbon from the atmosphere, helping mitigate the impacts of climate change. The restoration of marshes can contribute to carbon sequestration, providing an additional environmental benefit.
• Storm surge protection: Healthy marsh ecosystems serve as a natural buffer against storm surge and coastal erosion. Their restoration can enhance the resilience of the coastline, providing protection to both wildlife habitats and nearby communities.
• Recreational opportunities: Improved marsh ecosystems offer recreational opportunities for people, such as bird watching, nature walks and fishing. This can promote ecotourism and create a greater appreciation for the importance of preserving natural habitats.
