ST. LOUIS (AP) — Mississippi River shippers have returned to hauling full loads after several storms and aggressive rock-clearing helped deepen the waterway, eliminating worries about barge traffic shutting down, the river's stewards and barge operators said Wednesday.
Barge operators had lessened their loads as the river's level fell, allowing the barges to sit higher in the water. But there have been concerns for months that if the water level fell much more, all barge traffic could be halted.
The recent reversal of that has the Army Corps of Engineers and the Coast Guard declaring victory, though they cautioned the threat to shipping on the vital corridor could return next winter as the nation's worst drought in decades has shown no signs of easing.
"I'd say we've gotten through the toughest period we're going to see in the low-water period," said Mike Petersen, a spokesman for the Army Corps of Engineers, which scrambled in recent months to clear rock pinnacles from a crucial stretch of the Mississippi south of St. Louis.
With recent storms that socked the nation's midsection with snow and rain, "Mother Nature met us halfway, and that's what we needed," Petersen added. "But it also took tremendous elbow grease to keep that open. We're all a little bit weary, but we're relieved to see the river come up and not have any groundings."
The Mississippi had been growing ever shallower with the drought and a seasonal cutback on the amount of water fed into it from the Missouri River at St. Louis. Barge operators compensated by lightening their loads, which increased shipping costs because more barges were required to move the same amount of cargo. That also caused towboats to go through more fuel because more trips became necessary.
As the industry worried a shutdown could be imminent, the Army Corps scrambled to keep the river at a minimum of 9 feet deep for safe barge navigation. For months, the river hovered just a few feet — and at times a few inches — above that level.
Blasting and removal of rock pinnacles added 2 feet of depth at a troublesome southern Illinois stretch, and recent storms fed the river and its tributaries.
On Wednesday, the river gauge at St. Louis showed a channel depth of about 18 feet. The National Weather Service said it expects the river to rise another 2 feet through the weekend before a gradual decline. But that forecast assumes no additional precipitation, and the approaching spring months typically are among the wettest of the year. Continued...
