The Mississippi River's water level is dropping again and barge industry trade groups warn that river commerce could essentially come to a halt by mid-January. Ice on the northern section of the Mississippi is reducing flow more than expected.
The Coast Guard remains confident that the nation's largest waterway will remain open despite the worst drought in decades.
But even if the Mississippi remains technically open, Deborah Colbert of the Waterways Council, a barge industry trade group, says further load limits will make shipping unviable by mid-January.
