Concern about the rapid loss of wetlands within the Pass a Loutre Wildlife Management Area located at the mouth of the Mississippi River has resulted in implementation of the Pass a Loutre Marsh Building Project. The project involved cutting artificial breaches through the natural river banks thereby allowing water and sediments to flow into and fill adjacent shallow bays and ponds. This method simulates the natural land-building process by which the wetlands of the Mississippi River delta were originally formed. This paper provides an overview of all steps in the project including planning, design, construction, and monitoring.
