In April 2009, the Mississippi River Sediment Delivery System was proposed to channel dredged sediment from the Mississippi River to the wetlands in South Louisiana to restore of tidal marsh. Approximately 200 million tons of sediment flows down the Mississippi River annually, of which the Army Corps of Engineers dredges about 60 million cubic yards of the sediment to maintain Louisiana's waterways. According to the project documents, if successful, the Sediment Delivery system could potentially create of marsh a year and reduce wetland losses by as much as two-thirds. The dredged sediment will be piped to Bayou Dupont via a pipe, to an area of open water and broken marsh. Once the area has been adequately filled, it will be planted with marsh grasses. It is estimated that the project will cost $28 million and be completed by August 2009.
