The $31 million project used dredged sediment to build 510 acres (206 hectares) of salt marsh and nourish another 90 acres. It also created 2.5 miles (4 kilometers) of earthen terraces.
The restored area had lost wetlands to drought, saltwater intrusion and hurricanes.
The agency says a project to build and nourish more than 580 acres of marsh is nearly complete. It’s near Cameron, and is called the Cameron-Creole Watershed Grand Bayou Marsh Creation project.
The authority has an online interactive map of its projects.
