Water gets churned up at the end of a dredging pipeline connected to a U.S. Army Corps of Engineers' dredge on the Mississippi River on Monday, Aug. 20, 2012 near Memphis, Tenn. Sand that is removed from the river bottom is spit out the end of the pipeline so it can be deposited on the riverbank. The Mississippi River from Illinois to Louisiana has seen water levels plummet due to drought conditions in the past three months. Near Memphis, the river level was more than 12 feet lower than normal for this time of year. (AP Photo/Adrian Sainz)
