Friday, May 17th, 2024

  • Arkansas High Flow Conditions – Starting May 5th, various vendors were stopped and / or standing by until river conditions improve due to high flows on the Arkansas River. As of May 13th, there has been local movement on the river, but the river continues to be shut down. Expecting traffic to resume by the end of this week / beginning of next week.
  • San Jac / Old River Conditions – Traffic is still backed up 12+ hours from the impact. Please contact your local dispatcher and / or sales representative regarding cancelation, make up, or alternative plans.
  • Lower Miss River Conditions – Due to the forecasted river stage and current operating conditions, ACBL has implemented tow-size restrictions varying across horsepower class. This reduction is expected to delay transit by 48-to-72 hours.
  • Highwater Upper Miss (UM01-200) Due to highwater Saint Louis south will create delays getting in and out of fleets and increasing transit times. There is also extreme drift in the river causing hazardous conditions. Currently there is a 20 percent reduction in tow size on the Upper Miss STL thru Cape both directions. Due to these conditions, our vessels will only operate daytime hours through Cape. These conditions are expected to last over the next week.
