ST. LOUIS (AP) — Missouri Gov. Jay Nixon and the barge industry are imploring the federal government to take steps to keep enough water flowing on the drought-ridden Missouri and Mississippi rivers to avert a potential "economic disaster."
Nixon sent a letter Friday to the Army's assistant secretary urging the Army Corps of Engineers to continue providing sufficient water flow from the Missouri to the Mississippi River. Current corps plans would reduce the amount of water released from the Missouri's upstream reservoirs starting next week.
"I urge the U.S. Army Corps of Engineers to avert potential economic disaster on this vital avenue American farmers use to get their goods into the world market," Nixon wrote to Jo-Ellen Darcy, assistant secretary of the Army.
Meanwhile, the American Waterways Operators and Waterways Council last week urged Congress and President Barack Obama to act or potentially see a halt to the transportation of millions of tons of essential goods up and down the Mississippi.
The corps' offices were closed Monday for Veterans Day, and messages seeking comment were not returned. That agency, the U.S. Coast Guard and other river interests have scheduled a news conference for Friday in St. Louis to discuss the current state and outlook for the Mississippi.
The corps said last week that the flow reduction to minimum winter levels is the first of several conservation measures necessary if drought conditions continue into 2013. The agency said precipitation levels remain below normal over the entire Missouri River basin.
Winter typically is a low-water period on the two big rivers, but the situation is more dire this year with many points along the waterways at or near historic lows. The Mississippi was at just over 9 feet in St. Louis on Monday, 16 feet below flood stage. It was at 1.5 feet at New Madrid in southeast Missouri, where flood stage is 34 feet.
The Missouri River was just over 5 feet in Hermann, Mo. (flood stage is 21 feet) and just under 5 feet at Leavenworth, Kan. (flood stage is 20 feet).
The low levels have been months in the making, fueled by the nation's worst drought in decades, which has turned soils bone dry throughout much of the Midwest. Any precipitation is quickly soaked up in the ground and doesn't make its way into the Mississippi or other key rivers.
"Some places have gotten a lot of rain, but those weren't huge runoff events to jack up the river," said Bob Holmes, a Missouri-based hydrologist for the U.S. Department of the Interior's U.S. Geological Survey.
To compensate, many barge owners now are required to carry lighter loads, costing them more per ton to move cargo but also reducing chances of running aground as crews hustle to dredge silt and other sediments from the river to clear passages.
The waterways association said the reduction in releases on the Missouri would have particular impact on the Mississippi River from St. Louis south to Cairo, Ill., the area between where the Missouri and Ohio rivers merge into the Mississippi. Association officials cite concern about rock formations near Thebes, Ill., and Grand Tower, Ill., that would threaten to stop barge traffic by around Dec. 10 if water levels drop as much as anticipated.
"The Mississippi River is an economic superhighway that efficiently carries hundreds of millions of tons of essential goods for domestic use as well as national export. We need to address this situation swiftly, cut through bureaucratic red tape, and prevent the closure of the Mississippi," said Tom Allegretti, the American Waterway Operators' president and CEO.
Allegretti's trade group said barges on those corridors carry 20 percent of the country's coal and more than 60 percent of its grain exports. A mix of other cargo — everything from petroleum products to lumber, sand, industrial chemicals and fertilizer — also gets shipped by river.
Because of the drought, the Mississippi has received as much as 78 percent of its water from the Missouri this year, compared with 60 percent in a normal year, according to Nixon's office.
"I know that alternative measures are being considered to maintain the Mississippi channel, including dredging and clearing of rock pinnacles along the river," Nixon wrote. "I urge you to fast-track and fully implement those efforts."
