ACBL’s Daily River Conditions

Updated Tuesday, September 27th, 2022

Today’s Key Issues

  • Historic Lower Miss Low Water Conditions – River Levels continue to fall on the Lower Miss with severe impacts to navigation not seen since 1988. Expect Industry to see significant delays to barge transits and ton-miles production driven by drastic reductions to boat and barge capacity.
    • ACBL is working to crew all available boats and mobilize equipment to combat these conditions.
    • Industry has reduced the SBD drafts to 9’6″. This change reflects a 20-27% reduction to tons per barge versus normal conditions. NBD drafts will remain at 9’6″.
    • Industry has agreed to 25-barge max tow size SBD, reflecting a 17-38% reduction in tow size.
    • Groundings have been driving intermittent closures of 12-36 hrs over the past two weeks. Industry has worked two groundings and corresponding closures today at MM 770 and 440.
    • Docks and harbors may see further draft restrictions locally, some reportedly at 7′ max.
    • USACE is engaging additional buoy boats to improve navigational aids as well as two dredges.
    • Expect these issues to continue well into October based on forecasted precip.
  • Hurricane Ian Update – The current track of this Hurricane expected to minimally impact the Inland River system. ACBL’s Hurricane Task Force is monitoring the storm and the Port of Mobile is on Port Condition Normal, while the ICW east of Panama City will move to Port Condition X-Ray. Those in Florida should be making final preparations or evacuation at the direction of local authorities as this Hurricane is projected to make landfall near the Tampa area.
  • Upper Miss Closeout – ACBL has published our final loading dates for shipments into the Upper Miss ahead of the Winter Closure. Our final loading dates from the Gulf origins will be October 10th for Dubuque, IA to St. Paul, MN and October 24th for St. Louis, MO thru Clinton, IA.

  • Cannelton Lock Main Chamber Closure (OR 720)Main Chamber closed for repairs July 6th through November 11th. Traffic will pass through the Auxiliary chamber, requiring two cuts for most tows. Between 9/26 and 9/30 there will be three 4-hour full closures to install anchor pins. Currently seeing 18+ hrs of delay and have 10 tows waiting as of this morning. Expect delays similar to the recent Belleville Lock closure (18-36 Hr).

  • Stack Island Dredging (LM485) – Work is expected to begin 09/30 and last for 10-14 days, potentially requiring intermittent closures in both directions.
  • Old River Lock (LM 305) – Daily closure started August 1st from 06:00-19:30 and lasts through August 29th. Additionally, a second closure commencing approximately August 30th through November 12th 2022 for installation of two miter gates and repairing lock chamber expansion joints, which will necessitate a full closure.
  • I-10 Bridge (LM229.3) – Safety advisory from LM228.5 – 230 AHP for the replacement of the fender system on Pier 5 of the I-10 bridge, on the left descending channel near MM229.3. The operation will be 24 hrs a day, 7 days a week from August 1, 2022 – June 30, 2023. Operations may extend in the channel at times and cause delays. Transit slowest safe speed to minimize wake.
  • Donaldsonville Daily Closure (LM189) – Daily closures starting approximately October 17th through November 8th 1900 – 0700 nightly for a pipeline removal project. Expect no closures 10/23-25 and 11/1-3 for a break in work.

  • Industry Manpower Issues – The Inland Maritime Industry continues seeing major shortages of manpower. This is directly impacting the ability to crew towboats. As a result, expect 1-2 day delays in boat timings throughout the system, increasing overall barge transits in kind. ACBL has taken measures to increase our workforce throughout the system. The safety of our Mariners is our highest operating priority. Accordingly, ACBL has implemented measures and training programs to keep all of our team members safe.
