FILE - This Nov. 28, 2012 file photo provided by The United States Coast Guard shows man-made dikes, perpendicular to the shore, that direct the water flow back into the river to maintain a navigable depth along on the Mississippi River South of St. Louis. The National Weather Service revised the Mississippi River forecast Wednesday, Dec. 5, 2012, offering a bit of a reprieve for shippers, showing the water level isn't dropping as quickly as feared. Still, at least two large barge companies already are reducing loads over concerns about the river's depth.
