Sediment Diversion

Lower Breton Sediment Diversion

  • Project TypeSediment Diversion
  • Project BasinBreton-Chandeleur Basin

This sediment diversion project is planned for lower Breton Sound along the east bank of the river. The brackish and salt marshes in the influence area have low rates of land loss relative to many other parts of the coast. This may be attributed to the sediment and fresh water it periodically receives when the river overtops the natural levee during high flows. This project will divert sediment and fresh water into the basin to build new land, maintain existing marshes and increase the resiliency of the influence area to sea level rise and storm events.
