Chicago/Illinois/Upper Miss

  • Upper Miss Low Water – The Upper Miss is forecasted to see decent water through mid-Jan and as such, we have regained tow size and increased loading draft guidance, for releases through this coming weekend.
    • ACBL Liquid drafts are 8”6” on the UMR, Illinois River and Tenn-Tom.
    • ACBL Dry loading drafts to 11′ SBD for barges loading St. Louis through Cairo, and will reevaluate Monday 1/9.
      • Drafts remain 8’6″ for NBD barges transiting to/from/through the St. Louis area; roughly 30-36% below normal drafts.
  • Upper Miss Closure for Dredging – The Dredge Jadwin is positioned at UM 46, requiring daily closures 0600 – 1800 for work. Expect traffic to pass each night once this begins and work to complete December 28th at 18:00.
  • Mel Price and Lock 27 Main Chamber Closures – Starting Jan 1, the main chamber at both Mel Price Lock (UM 200) and Lock 27 (UM 185) will be closed for maintenance. While the Auxiliary chamber will be in use, expect a potential for multi-day delays to transits above St. Louis. Ice conditions could exacerbate the impact of this work, scheduled through the end of March.
    • As of Jan 4th, there has been minimal delay due to this work.
  • Ice Conditions on the Illinois River and Upper Miss – Ice conditions are improving on the Illinois, but we remain impacted with Ice Couplings required at most locks.

    • ACBL began building tow with Ice Couplings out of Cairo 12/16.
    • Tow sizes Chicago to Cairo have returned as of the New Year.
  • Lagrange Lock Delays – Due to congestion as fog delays, there is a 20-boat queue at Lagrange Lock (IR 82). Expect 3-day delays to transit, and the backlog to clear over the next week.
