US Gulf:
Leland
Bowman Lock operators continued to enforce two-hour wait times between lockages
due to low water levels, leading to 24-56 hour delays. A reported 33 tows were
queued to pass the site on Sept. 14.
Reverse
head conditions kept Harvey Lock closed for the week, sources said. Daytime
shutdowns began on Sept. 11 in the Morgan City, La., area for bridge repairs,
leaving transit unavailable at Mile 1 of the Port Allen Route between 7:00 a.m.
and 7:00 p.m. through Sept. 25.
A
planned repair closure at Algiers Lock was pushed back to Oct. 2 and will run
through Dec. 1. Guidewall work at Bayou Sorrel Lock, underway through March
2024, slowed navigation from 7:00 a.m. to 4:00 p.m. daily.
Brazos
Lock repairs, reported blocking travel daily between 7:00 a.m. and 7:00 p.m.,
resulted in delays up to 23 hours. The project is scheduled through Nov. 29.
Dredging at Bayou Chene, set to run through Nov. 30, prompted ongoing
slow-travel warnings in the area.
Port
Allen Lock waits ran up to five hours during the week, according to Corps data,
while intermittent 20-hour waits were observed at Industrial Lock. Travel
delays reported up to two weeks or more in the Panama Canal could continue into
mid-2024 due to drought conditions, according to reports.
Mississippi
River:
Low-water
conditions on the Lower Mississippi River intensified during the week, sources
noted, forcing tighter towing restrictions. Loading drafts on northbound tows
traveling between the Gulf and Cairo, Ill., were reduced by 25-30%, increasing
from 20% one week earlier. Tows traveling downriver saw draft reductions of
20-25%, up from 15-20% at last report.
In addition,
maximum barge counts were reduced by 15-40% on the lower river, depending on
location and vessel horsepower, jumping from 10-15% noted previously.
Altogether, the restrictions stretched delivery windows by 48-72 hours, above last
week’s 24-48 hours.
Drafts continued
to be reduced by 15% in the St. Louis area as well as on travel between St.
Louis and Cairo. Towing widths were limited to four barges on the
mid-Mississippi.
The river gauge
at Vicksburg, Miss., was reported at a low-stage (-)2.37 feet and falling on
Sept. 14, while the Memphis, Tenn., gauge returned a low-stage (-)10.22-foot
reading. On the upper river, St. Louis was recorded at (-)3.47 feet and holding
steady on Sept. 14.
Following
numerous reported groundings, several dredges were working on the lower river,
including at Miles 527-538 and 925-928, with delays reported at 24-36 hours
through both locations. Dredging was expected in the Vicksburg area starting on
Sept. 16.
Upper-river
locks are scheduled to begin closing for the winter navigation season on Dec.
5, with spring reopening projected to commence on March 5-11, 2024. Barges
destined for Clinton, Iowa, or higher are expected to conclude 2023 departures
from NOLA during the first week of October, while cargoes delivered to ports
below Clinton will continue loading into the third week of October. Locks 18-27
are scheduled to remain open throughout the winter season.
Illinois
River:
Draft reductions
on the Illinois River continued at 15% due to low water levels. Wickets at both
Peoria Lock and LaGrange Lock were noted in the raised position during the
week, forcing tows to lock through both locations.
Repairs and
maintenance at Brandon Road Lock, Dresden Island Lock, and Marseilles Lock are
scheduled through Sept. 30, closing the river to commercial navigation.
Ohio
River:
Maximum loading
drafts remained at 10.0-10.5 feet on the Ohio River due to low water levels.
Monongahela River drafts were capped at 8.5 feet.
Sources reported
a temporary shutdown at Miles 967-975 during the week due to dredging. The area
was partially reopened by Sept. 13, allowing southbound vessels to run during
daytime hours and northbound tows to pass overnight. The project is tentatively
scheduled through Sept. 24.
The John T.
Myers Lock auxiliary chamber returned from miter gate repairs on Sept. 10,
sources said. The main chamber subsequently closed on Sept. 11, forcing detours
through the newly reopened auxiliary chamber until Nov. 17. Waits were reported
up to 17 hours.
The primary
chamber at Montgomery Lock is closed for repairs and maintenance through Sept.
25. Travel through the secondary chamber will be unavailable on Sept. 25-Oct.
17 and Nov. 22-26, while additional main chamber outages are planned for Oct.
17-Nov. 22 and Nov. 26-Dec. 22.
The Smithland
Lock land chamber will shut from Sept. 22 through Oct. 21 for repairs, followed
by a river chamber closure on Oct. 22-Nov. 20. Assist boat usage was compulsory
on southbound lockages through Smithland during the week due to strong
outflows.
Arkansas
River:
Travel through the Port of Catoosa will be
restricted to daytime hours until further notice, sources said. Joe Hardin Lock
was closed for repairs on Sept. 11-15, and passage through Webbers Falls Lock
was scheduled to be unavailable on Sept. 11-17.
