Hydrologic Restoration

Calcasieu Ship Channel Salinity Control Measures

  • Project TypeHydrologic Restoration
  • Project BasinChenier Plain
  • ParishCalcasieu, Cameron, Jefferson Davis, Vermilion

This project is located in the Calcasieu Ship Channel which connects the Gulf to Calcasieu Lake. The Chenier Plain was once a stable platform, but dredging of navigation canals dramatically changed the hydrology of the system. Saltwater intrusion led to the extensive loss of freshwater marshes and increased the threat of storm surge to communities in the lake’s interior. This project will build structures that will limit saltwater intrusion through the Calcasieu Ship Channel and into adjacent marshes and could also provide minor storm surge protection in the ship channel.
