US Gulf:
Algiers Lock is closed for gate repairs through Dec.
1. Vessels were reported detouring through the Port Allen Route, adding 24-48
hours to travel times.
Guidewall repairs shut Bayou Sorrel Lock from 7:00
a.m. to 4:30 p.m. daily, resulting in 15-25 hour delays for the week. Tows
arriving before 4:30 p.m. were permitted to lock before the next morning’s
shutdown, regardless of the hour. The closures, scheduled until March 2024,
will be temporarily suspended whenever wait times exceed the 24-hour mark,
sources said. Concrete work is scheduled to completely close the site on Oct.
31.
Low head conditions continued to limit Harvey Lock
movements following the site’s Oct. 16 reopening. Tows were limited to 300-foot
lengths and 70-foot widths during the week, resulting in waits up to 32 hours.
Harvey had been shut since June 15 due to reverse head conditions.
Brazos
Lock saw limited availability between
7:00 a.m. to 7:00 p.m. daily, scheduled to continue until Nov. 29. Intermittent
wait times were noted up to 20 hours through the week. Dredging at Bayou
Chene, slated to run through Nov. 30, prompted slow-travel warnings in the
area.
Planned
maintenance at the Ellender Bridge, located at Mile 243 of the West Canal, will
block navigation from 8:00 a.m. to 8:00 p.m. on Nov. 11-12, and again on Nov.
18-19.
Port
Allen Lock delays were observed at 2-3 days due to congestion from the Algiers
Lock shutdown, falling from 2-4 days at last report. Industrial Lock waits
topped out at five hours.
Mississippi River:
Low water levels continued on the Mississippi River
during the week, though forecasts hinted at improving conditions headed into
November.
The river gauge at Memphis, Tenn., was posted at a
low-stage (-)9.44 feet and rising slowly on Oct. 26, above the (-)11.85-foot
record low set on Oct. 16. The river gauge at Vicksburg, Miss., reported at
(-)0.18 feet at midweek, was predicted to cross above the 0.00-foot mark on
Oct. 30.
As a result of the slightly improved conditions,
restrictions on southbound loading drafts softened to 20-25% on travel between
the Gulf and Cairo, Ill., down from 25-30% reported previously, while
restrictions on northbound loading weights continued in the 25-30% range.
Tows were capped at five-barge widths between Cairo
and Mile 303 of the lower river, equating to a 5-15 barge reduction from
typical towing lengths, depending on vessel horsepower. The smaller barge
counts, combined with reduced loading weights, were expected to stretch
delivery times by 48-72 hours.
Dredging and delays were reported on the lower river
at Miles 703, 437, and in the Baton Rouge, La., area. Dredging at Mile 293 did
not impact navigation during the week, sources said.
Forecasts showed the largest potential for
improvement in the St. Louis area, where depths of (-)0.55 feet recorded on
Oct. 26 were projected to rise to 6.8 feet on Nov. 8. Loading drafts continued
to see 30-35% reductions through the St. Louis harbor, while maximum four-barge
towing widths and a 5-10% reduction in loading drafts persisted on travel
between St. Louis and Cairo. Dredging was reported at Miles 481, 221, 158-159,
and 38.
Upper-river locks are scheduled to close for the
winter navigation season between Dec. 5 and March 11, 2024.
Illinois
River:
Maximum loading
drafts were reported at 9.0 feet on the Illinois River, while towing lengths
were limited to 15 barges during the week. Wickets were reported in the raised
position at Peoria Lock and LaGrange Lock, forcing tows to lock through both
locations. Dredging previously reported at Miles 226-228 concluded on Oct. 25,
sources said.
Ohio
River:
Southbound
loading drafts were cut by 10-15% on the Ohio River due to low water levels.
Drafts were previously reported at 9-10.5 feet, depending on location. Draft limits
continued at a maximum 8.5 feet on the Monongahela River.
Dredging
underway at Miles 967-975 was scheduled to wrap up on Oct. 31. The project has required
one-way travel through the area, restricting northbound tows to overnight
transits, while southbound movements passed during daylight hours.
The primary
chamber at John T. Myers Lock is shut for repairs and maintenance through Nov.
6, prompting detours through the secondary chamber. Delays stretched into the
2-5 day range, according to Corps data, above 51-84 hours at last report.
The main chamber
at Montgomery Lock is shut through Nov. 22. Following the current closure, the
site’s auxiliary chamber will shut on Nov. 22-26. The main chamber will close
once more on Nov. 26-Dec. 22.
Arkansas
River:
Montgomery
Point Lock has been shut to navigation since Oct. 16 due to low water levels,
effectively closing the Arkansas River. Dredging to reopen the site began on
Oct. 21, sources said, and was expected to wrap up on Oct. 27-28.
