The extreme drought impacting the Mississippi, Ohio and Tennessee river valleys continues to translate into troublesome low water conditions-and in some places record lows-on the Western Rivers, with draft restrictions slowing the movement of barges on many waterways. The Lower Mississippi River at Memphis, Tenn., hit a record low October 17, when the gage on the east bank near Mile 735 registered -10.79 feet. The previous record low was -10.7, set on July 10, 1988. Similarly, the Ohio River gage in Cairo, Ill., has also hit a record low of late. "The river levels from Cairo, Ill., to Memphis, Tenn., are representative of 1988 levels, while locations downstream are closer to 2012 levels," Jeff Graschel with the Lower Mississippi River Forecast Center said in an October 20 low-water update. |
