Lower Miss/Gulf/Canals/Tenn Tom

  • Arkansas River ReopenedMovement on the Arkansas resumed 5/4 after a 4-day closure due to High Flows. Tow-size remains at 6 barges, or 50% of normal operation. Expect conditions to improve by mid-May, but it will depend on forecasted weather.
  • Gulf and Canals Weather UpdateSevere storms moving through NOLA and the region today, 5/5. Expect delays to barging operations and transit on the Canals. Once this system blows through expect good operating conditions through the weekend, with a chance for fog overnight.
  • High Water Outlook– Expect the current recovery from High Water restrictions to be short lived in the Gulf and on the Lower Miss. The forecasts show us above 12′ in New Orleans on 5/12. We are currently seeing 14-20% tow size restrictions and boat-by-boat daylight restrictions at Vicksburg. Further precipitation would drive us back into flood stage conditions late May. 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
  • Lower Miss Work at Randolph Bluff Due to rock-laying revetment work at Randolph, LM 770, the river will see delay daily 0600 – 1800 4/27 through 5/31. Contractors have advised they will be able to pass southbound and northbound boats on a case-by-case basis. Expect this slow-down to cause 6-12 hrs delay depending on daily traffic.
  • Algiers Lock Restrictions – Until further notice, tows over 60′ wide restricted to 600′ total length, and tows less than 60′ wide restricted to 700′ total length. Two 30K barges or Four regulation barges are able to lock through in one go, but greater configurations will require trip boat assistance.
  • Harvey Lock Closures – Harvey will close 4/5 – 5/21 for repair work to the 4th Street Lift-Bridge. Expect increased traffic and delays at Algiers. High water could increase the impact of this issue.
  • Bayou Chene Closure – Due to entering a critical phase of floodgate construction and diving operations, expect nightly closures (1900 – 0700) and an assist vessel requirement for transiting Bayou Chene (Morgan City bypass). These changes take effect 4/14. May drive delays to transit of the West Canal through the Morgan City area of 6-12 hrs.
  • Grosse Tete Bridge Reopened on the Port Allen – Grosse Tete drawbridge (PA 36) closed intermittently 3/15 through 5/1 for repairs. Expect transit to resume to normal by mid-May.
  • Port Allen Route Reopened– Transit has resumed late 4/27 at Bayou Sorrel and on the Port Allen route. USCG had ceased operation of the Bayou Sorrel lock and closed navigation 4/16. The Port Allen remains backed up, but expect recovery to normal operating conditions by mid-May.
  • Port Allen Lock Restrictions – Due to a barge allision and damage to the guidewall, the following restrictions will be in place: Westbound tows with more than 1 barge will be permitted to lock with an assist vessel, while only single-barge tows will lock without assist. Eastbound tows greater than 650′ long will require an assist vessel. Due to these restrictions, expect a potential for delays to lockages.
