Today’s Key Issues

  • Cheatham Locks and Dam (CR 149) Starting an 11 day full closure on 5-10-21. Intermittent closures for repair will run through 7-15-21.
  • Lower Miss Closure – Dredging Operations expected to begin Friday 5/7 at Winchester, LM 900, for 6 days. Expect to pass traffic with intermittent delays of 6-12 hrs.
  • Chickamauga Lock and Dam (TR 471) FULL closure from 5-3-21 to 5-24-21 for a full electrical rehab on the lock operating system.
  • Wilson Locks and Dam (TR 259) – Main Chamber CLOSED for repairs from 5-4-21 to 5-14-21. Auxiliary chamber will be used during this time, expect 6-12 Hrs delay.
  • High Water Outlook in the Gulf – Expect the current recovery from High Water restrictions to be short lived in the Gulf and on the Lower Miss. We are currently seeing 14-20% tow size restrictions and boat-by-boat daylight restrictions at Vicksburg. The forecasts show us above 12′ in New Orleans on 5/12 and approaching 35′ at Baton Rouge 5/18. As a reminder, ACBL High Water provisions begin when the Baton Rouge gauge is 35′ and above, while ACBL Gulf Fleet surcharges begin when the New Orleans (Carrolton) gauge is 12′ and above.
  • Industrial Lock Closure – Lock will be closed 0600 – 1830 Tuesday 5/11 for concrete pouring on new dolphins. Expect additional 12 hrs of delay through Wednesday 5/12.
  • Algiers and Industrial Lock Delays – Industrial (East Canal) continues to see delays of 20-30 hrs due to traffic. Traffic and ongoing tow size restrictions remain driving 1+ days of delay at Algiers (West Canal). These conditions continue to contribute to a week or more delay to shipments between the Lower Miss and West Canal
  • Gulf and Canals Weather Update – Good operating conditions forecast through Sunday, 5/9, when storm fronts will move through the region. Expect delays to transit on the Canals to start the week and a potential for fog overnight in the Gulf.

HIGH WATER OUTLOOK

See below for current forecasts of the Baton Rouge and New Orleans Gauges. We are watching these gauge forecasts intently, as the long-range currently shows us back into firm restrictions mid-May. Currently seeing boat-by-boat daylight restrictions at Vicksburg and 14-20% sustained reduction in tow sizes on the Lower Miss.

The below would indicate New Orleans to move above 12′ on 5/12, which enacts further restrictions to Shuttle Boat tow size and on fleeting. Similarly, the Baton Rouge gauge is approaching and may go above 35′ on 5/18. As a reminder, ACBL High Water provisions begin when the Baton Rouge gauge is 35′ and above, while ACBL Gulf Fleet surcharges begin when the New Orleans (Carrolton) gauge is 12′ and above
