ST. LOUIS (AP) — Crews might be allowed to begin destroying two rock pinnacles impeding barge traffic on the Mississippi River as early as next week, more than a month ahead of schedule, a senator said Tuesday, cautioning that further steps may be needed to ensure the vital shipping route remains open.
U.S. Sen. Roy Blunt, R-Mo., and two river industry trade groups said Tuesday that the Army Corps of Engineers informed them that blasting could start next week, although it wasn't clear which day the work could start or how long it might take. The corps didn't respond to several messages seeking comment.
Removal of the rocks is an important step in keeping the river open to barge traffic. Months of drought have left water levels up to 20 feet below normal along a 180-mile stretch of the river from St. Louis to Cairo, Ill. The problem was made worse last month when the corps cut the outflow from an upper Missouri River dam by two-thirds — meaning far less Missouri River water flows into the Mississippi.
Officials with the trade groups American Waterways Operators and Waterways Council Inc. said expediting the rock removal will help, but they maintain that the corps also needs to restore some of the Missouri River flow.
"The release of sufficient water from Missouri River reservoirs during the time this rock pinnacle work takes place is essential to preserving a 9-foot channel on the Mississippi River that will sustain commercial navigation and the movement of our nation's critical commodities and exports," said Michael J. Toohey, president and CEO of Waterways Council Inc.
"The corps is finally heeding my calls to expedite rock removal & help prevent a river crisis," Blunt wrote on Twitter. "Water releases from the MO River must be next."
The corps removed many rock pinnacles in the southern Illinois area more than two decades ago. Sonar wasn't as advanced in the late 1980s and new technology recently revealed formations they missed near the towns of Thebes, Ill., and Grand Tower, Ill.
