Sediment Diversion

Atchafalaya River Sediment Diversion

  • Project TypeSediment Diversion
  • Project BasinTerrebonne-Atchafalaya Basin

To be constructed off the Atchafalaya River, the Atchafalaya River Sediment Diversion will provide basin-wide benefits to marshes in southwest Terrebonne Parish. Sediment and fresh water diverted into the marshes will help build land and sustain other nearby projects planned for construction, like Mauvais Bois Ridge Restoration. This project will have the greatest benefits to freshwater habitats, such as forested areas, flotant and fresh and intermediate marsh, which are threatened by saltwater intrusion and sediment starvation.
