This project was previously named the East Maurepas Diversion on our website.  This diversion, planned near Angelina, will provide sediment and fresh water to existing wetlands in East Maurepas swamp. Dominated by bald cypress and water tupelo trees, the Maurepas swamp complex is one of the largest forested wetlands in the nation. However, levees constructed along the river have isolated the area from spring floods and the vital fresh water, nutrients and sediment they bring. This isolation, coupled with rising …

Union Freshwater Diversion

Union Freshwater Diversion will convey fresh water from the Mississippi River into West Maurepas swamp near Burnside. Nutrient-rich freshwater inputs to the fresh-forested, flotant and freshwater marsh environments will prevent saltwater intrusion and encourage vegetation growth. The diversion will also convey fine sediment to nourish existing wetlands or create new wetlands in Maurepas swamp. Ascension, Livingston, St. James and St. John the Baptist parishes are all expected to receive flood-reduction benefits from this project. The fine grain sediment may also …

Central Wetlands Diversion and Wetland Restoration

This diversion will benefit the Central Wetlands Unit ecosystem east of New Orleans, an area destroyed by logging and by saltwater intrusion from the now-closed Mississippi River Gulf Outlet (MRGO). Once primarily a freshwater system dominated by bald cypress swamp and freshwater marsh, the predominant habitat type today is brackish marsh. Regional MRGO-area ecosystem restoration will help rebuild and sustain marsh and swamp, providing storm surge protection for New Orleans and nearby communities.
