US Gulf:
Two-hour waits continued between lockages at Leland
Bowman Lock due to low water levels, although delays were much improved. Tows
were reported waiting up to six hours to pass the site, falling from 24-56
hours noted one week earlier.
Harvey
Lock remained shut to navigation due to reverse head conditions. BNSF railroad
bridge repairs at Morgan City, La., blocked travel daily between 7:00 a.m. and
7:00 p.m. The project is scheduled through Sept. 25.
Side
gate repairs are scheduled to shut Algiers Lock from Oct. 2 to Dec. 1. Sources
tied the work to damage sustained from a vessel collision in July. Bayou Sorrel
Lock guidewall repairs prompted daily shutdowns from 7:00 a.m. to 4:00 p.m.,
causing waits up to 24 hours. The effort is scheduled to continue into March
2024.
Brazos
Lock repairs underway through Nov. 29 limited travel between 7:00 a.m. and 7:00
p.m. daily, triggering delays up to 28 hours. Dredging at Bayou Chene is
scheduled through Nov. 30, necessitating slow-travel warnings through the area.
Port
Allen Lock saw 4-7 hour delays during the week, while tows waited up to 20
hours to pass Industrial Lock. Intermittent 4-6 hour wait times were reported
at Colorado Lock.
Mississippi
River:
Low-water
conditions continued on the Lower Mississippi River, extending towing
restrictions. Tows traveling upriver between the US Gulf region and Cairo,
Ill., saw maximum loading drafts cut by 25-30%, while downriver drafts were
reduced by 20-25%. Barge counts were restricted by 15-40% on the lower river,
sources said, depending on location and horsepower, contributing to 48-72 hour
delays.
Draft limits
were cut by 15% on travel between Cairo and St. Louis, as well as through the
St. Louis harbor. Maximum towing widths were restricted to four barges on the
mid-Mississippi.
The Vicksburg,
Miss., river gauge was noted at a low-stage (-)1.54 feet and holding on Sept.
21, while the Memphis gauge returned a low-stage (-)9.49-foot reading at
midweek. St. Louis depths were posted at (-)1.96 feet on Sept. 21.
As groundings
continue to be reported throughout the eastern river system, sources described
at least four dredges in operation on the Lower Mississippi during the week,
including at Miles 437, 487, 537, and 925. Dredging was also underway at Mile
28.6 of the upper river.
Upper-river
locks are projected to begin closing for the winter navigation season on Dec.
5, with the spring reopening scheduled for March 5-11, 2024.
NOLA-loaded
barges slated for delivery at or above Clinton, Iowa, were expected to conclude
2023 departures during the first week of October. Cargoes headed to ports below
Clinton will continue loading through the third week of October. Locks 18-27
are expected to remain open through the winter.
Illinois
River:
Illinois River
draft reductions continued at 15% for the week due to low water levels. Wickets
were reported up at Peoria Lock and LaGrange Lock, forcing lockages at both
sites.
Repairs and
maintenance underway at Brandon Road Lock, Dresden Island Lock, and Marseilles
Lock are scheduled to conclude on Sept. 30. The work has effectively halted
commercial navigation on the Illinois River since June.
Ohio
River:
Maximum loading
drafts remained at 10.0-10.5 feet on the Ohio River due to low water levels.
Drafts were limited to 8.5 feet on the Monongahela River.
Dredging
reported at Miles 967-975 was expected to run through Sept. 24. The project limited
southbound travel to daylight hours, while northbound vessels were restricted
to overnight navigation.
The John T.
Myers Lock primary chamber is shut through Nov. 17, forcing detours through the
secondary chamber. Delays were reported in a wide 16-52 hour range during the
week.
The Montgomery
Lock main chamber is offline for repairs and maintenance through Sept. 25.
After the main chamber reopens, the auxiliary chamber will close on Sept.
25-Oct. 17 and Nov. 22-26. Additional main chamber shutdowns are scheduled for
Oct. 17-Nov. 22 and Nov. 26-Dec. 22.
The land chamber
at Smithland Lock is offline through Oct. 21 for repairs. The site’s river
chamber will shut on Oct. 22-Nov. 20. Smithland tows were required to lock with
an assist boat during the week due to strong outflows, sources said.
Arkansas
River:
Joe Hardin Lock and Webbers Falls Lock were
scheduled to return from planned repairs on Sept. 15 and Sept. 17,
respectively.
