Pontoons extend from the tubing of the Dredge Jadwin, a U.S. Army Corps of Engineers vessel that is clearing out some of the silt and left over mud and debris from last year's record flood on the Mississippi River and cutting a deeper channel for barges and their towboats to navigate north of Greenville, Miss., Wednesday, Aug. 22, 2012. The pontoons help the vessel stabilize and position itself as it removes river silt and carves out a new channel. (AP Photo/Rogelio V. Solis) less
