Lower Miss/Gulf/Canals/Tenn Tom

  • Historic Lower Miss Low Water Conditions – River Levels remain impactful through Dec on the Mississippi River with sustained severe impacts to navigation not seen since 1988. Industry continues incurring significant reductions to boat capacity, which has in turn drastically decreased ton-mile productivity for the inland rivers since early Oct.
    • ACBL has taken the lead within the Inland Marine Industry, working with our partners at the USCG and USACE to mobilize resources in troublesome areas and manage marine traffic.
    • ACBL and Industry have seen improved transits and run-time on the Lower Miss during November, but draft and tow restrictions remain an impediment.
    • December is forecast to see another fall in river levels, and expect restrictions, particularly St. Louis through Cairo, to degrade Industry capabilities by mid Dec.
    • Industry reduced Lower Miss drafts to 9’0″ on October 17th both NBD and SBD. This change reflects a 24-30% reduction to tons per barge versus normal conditions.
    • USCG and Industry have agreed on SBD tow size restrictions to 6-widths currently, expected to be at 5-widths when the river falls mid-Dec. 6-wide reflects a 15-25% reduction in tow size.
    • ACBL Liquid drafts have been reduced to 8’6″ as of October 17th, reflecting approx 17% reduction to tons per barge versus normal conditions.
    • ACBL has proactively reduced loading drafts to 8’6″ for barges transiting to/from/through the St. Louis area ahead of a sharp decline forecast for Dec.
    • Expect these issues to continue into 2023 based on forecasted precip.
  • Rob Roy Bridge Closure (AK 67.4) – Daily closure expected from 06:00 to 22:00 starting December 5th thru the 8th to facilitate repairs. An additional closure may be required from December 12th thru the 15th if work in both towers is not completed.
