Sediment Diversion

Lower Barataria Sediment Diversion

  • Project TypeSediment Diversion
  • Project BasinBarataria Basin
  • ParishJefferson, Lafourche, Plaquemines

This is a sediment diversion into what used to be marsh but is now lower Barataria Bay. Remaining marshes in the project’s influence area are rapidly becoming open water due to high rates of subsidence and erosion, without the benefit of new sedimentary inputs from the river. This project will reconnect the river to the influence area by diverting sediment and fresh water to build new land, provide a sediment source to the Barataria Basin barrier islands, restore historical salinities in the basin and help buffer communities in lower Plaquemines Parish from storm surge.
