were slashed by 15-20% on northbound travel between New Orleans, La., and
Cairo, while drafts were reduced by 10-15% for southbound movements. Barge
counts continued to run 15-25% below normal levels, depending on vessel
horsepower, stretching delivery windows by up to 24-48 hours.
Excessive
rainfall in the forecast was expected the lift the St. Louis river gauge to an
8.1-foot crest on Aug. 5, up from 1.66 feet on Aug. 3. Levels were likely to
