"  Bayou Dupont Sediment Delivery System Excavation of canals for navigation, oil and gas helped transform Bayou Dupont from wetlands to open water. This $26 million project, completed in May 2010, used pipelines to transport dredged river sediment, replenishing existing marsh and creating 577 acres of new land. Lake Hermitage Marsh Creation Experts estimate that without intervention one-third of this intertidal wetland will vanish by 2050. The $38 million project, which begins construction this year, will pump hydraulically dredged river sediment onto degraded marsh, creating 593 acres. Dikes will protect the shoreline, and nearly 5 miles of terraces will reduce turbidity. Little Lake Shoreline Protection To counter shoreline erosion and subsidence, this $29 million project, completed in 2007, has begun rebuilding 3000 acres of fragile marshes in the Barataria Basin with a 24-inch dredge pipe that deposits lakebed sediment onto wetlands. Shoreline dikes extend for approximately 4 miles. Benefits over the past four years: 488 acres created and 532 existing acres maintained. Barataria Basin Land Bridge This $34 million project, completed last March, uses hydraulically dredged material to nourish 1534 acres of natural levee ridges, swamps and freshwater marshes and will eventually create 1246 new acres of marsh. Myrtle Grove Water and Sediment Diversion Unlike other coastal restoration projects, many of which involve dredging sediment from the Mississippi and transporting it as slurry in pipelines to rebuild wetlands, Myrtle Grove will divert up to 45,000 cubic feet per second of sediment-laden water onto depleted marshes. A 90-foot-wide structure (above, left) with three bays of gates will control the flow.  "^^<http://www.w3.org/2001/XMLSchema#string>
