ACBL’s Daily River Conditions

Friday, May 24th, 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 17th, operations resumed with reduced movement on the river and expecting normal transits sometime this week.
  • Gulf Recovery Update – ACBL’s operations were extremely impacted by high winds and severe storms overnight on May 16th. Our teams actively worked to assess damages to equipment and secure our customers cargo. These recovery efforts lasted through the weekend and normal operations are expected to resume later this week regarding barge availability and transits.
  • 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.
