NEW ORLEANS (AP) - The Army Corps of Engineers says it will spend $16 million to raise 5 miles of rock shoreline in the Manchac Wildlife Management Area along Lake Pontchartrain.
The agency says it has hired Luhr Bros. Inc, an Illinois-based company, to do the work. Under its contract, Luhr will place new rock on the existing breakwaters built on the western shore of Lake Pontchartrain in 1994. The new rock will raise the breakwaters to an elevation of 3 feet and fill in gaps.
Also, dredged material from the bottom of the lake will be pumped behind the breakwaters to help create 110 acres of marsh.
The agency expects the work to reduce erosion and stem saltwater intrusion into a large freshwater pond known as "The Prairie," a favorite spot for ducks.
