BATON ROUGE, La. (AP) — The Louisiana Coastal Protection and Restoration Authority says it has built or renewed 600 acres of marsh in Cameron Parish, and has nearly completed a slightly smaller project.

The authority announced Friday that the Oyster Bayou Marsh Creation and Terracing project is complete.

The $31 million project used dredged sediment to build 510 acres of salt marsh and nourish another 90 acres. It also created 2.5 miles 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.
