U.S. Gulf:
Emergency dredging reported blocking overnight Port
Allen Lock navigation concluded on Nov. 20. Extensive delays persisted on Nov.
22, however, with Corps data showing wait times in the 2-4 day range. The
delays were expected to slowly dissipate through the course of the week.
Travel through Bayou Boeuf Lock continued to be
unavailable during daylight hours on weekdays, limiting movements to 7:00 p.m.
through 7:00 a.m., Monday through Friday. Full 24-hour access resumes on
Saturday and Sunday, a Coast Guard posting indicated.
Bayou Chene was shut to overnight movements due to
an ongoing floodgate construction project. A Coast Guard posting described the
channel as closed nightly between 7:00 p.m. and 7:00 a.m., while daytime tows
were capped at 600 feet of length. Configurations wider than 54 feet were required
to use an assist vessel. Waits were heard in the 6-12 hour range for the week.
Draft limitations due to shoaling remained at a
maximum 10 feet through Miles 113-116 of the Atchafalaya River in the Morgan
City area. Vessel lengths maxed out at 600 feet, while tows measuring above 400
feet were strongly encouraged to make use of an assist vessel. Tow widths were
limited to 70 feet. The Coast Guard advised boats to detour through the Port
Allen Route to avoid the restrictions.
Tows locking through Algiers Lock were limited to
four standard barges or two 30,000 mt tankers when traveling without
assistance. Larger configurations were possible with the use of an assist tug,
however. The restrictions were in place until further notice.
Belle Chasse Bridge construction underway through
late 2022 is expected to trigger intermittent navigational stoppage up to 12
hours at a time. Located at Mile 3 in the West Canal, slowdowns at the site
could affect Algiers Lock movements as well.
Most Industrial Lock movements fell in the 6-13 hour
range on Nov. 22, while intermittent delays were reported up to 27 hours.
Vessels transiting Algiers Lock experienced waits up to 11 hours, and sporadic
Calcasieu Lock wait times were noted in the 6-10 hour range. Corps data put
Brazos Lock delays up to 11 hours for the week.
The 2021 Atlantic hurricane season will officially
conclude on Nov. 30. The National Hurricane Center reported zero tropical
disturbances in the Atlantic on Nov. 23.
Mississippi River:
Channel reinforcement efforts were underway at Miles
343-346 on the lower Mississippi River, restricting downriver travels to 20-25
barges per tow during daytime hours. Boats traveling upriver were not affected.
Full navigation through the area was possible in both directions between 7:00
p.m. and 6:00 a.m. nightly. The project was scheduled to run through Dec. 1.
Rock-laying efforts scheduled for Dec. 1-15 are
expected to disrupt navigation at Mile 595.
Locks located on the upper Mississippi River are anticipated
to begin closing for the winter season on Nov. 28, beginning with Locks 5A, 8,
and 10. Locks 4, 5, and 7 are due to halt navigation on Dec. 6, followed by Locks
15 and 24 on Jan. 1, 2022.
Lock 24 is projected to return to service on Jan.
31, followed by Lock 15 on March 3 and Lock 5 and Lock 7 on March 11. Lock 5A,
Lock 8, and Lock 10 are on the calendar for a March 17 reopening, while Lock
4’s planned March 21 opening is expected to mark a full return to spring
navigation on the upper river.
Five-hour delays were noted at Lock 24 during the
week.
Illinois River:
Brandon Road Lock is scheduled to begin a repair and
maintenance operation on May 9, 2022. The work will trigger daytime travel
shutdowns at the site through Aug. 14, with tows limited to 70-foot widths
during travel-permitted hours. A full shutdown is on the books for Aug. 15
through Sept. 4, followed by a return to overnight-only navigation on Sept.
5-8. The project is expected to conclude on Sept. 9.
Wickets were heard coming up at Peoria Lock on Nov. 22, marking a return to lockages through the site. LaGrange Lock was expected to follow suit in the near future. Vessels were previously noted passing both locations through the nonlocking navigational pass.
Ohio River:
Cannelton Lock primary chamber repairs initiated on
June 21 concluded on Nov. 19, ending a bout of secondary-chamber navigation.
The Corps has proposed an additional round of maintenance in 2022, tentatively
set to run from July 5 through Nov. 11.
Repairs and maintenance in progress at the
Montgomery Lock primary chamber are on the books through Dec. 22 after starting
on Oct. 29, later than the original Oct. 18 plan. Boats were noted passing
through the auxiliary chamber, with Corps data showing wait times in a wide 3-6
day range, rising from 3-5 days in the prior report.
A
Hannibal Lock main chamber repair project previously scheduled to conclude on
Oct. 29 was extended through Dec. 10, leaving tows to detour through the site’s
600-foot secondary chamber. Additional work has been proposed at the site,
scheduled for July 5 through Oct. 8, 2022.
The
DashieldsLock auxiliary chamber remained closed for navigation due to an
underwater obstruction. Transit was possible through the site’s main chamber,
with minimal delays reported.
Kentucky
Lock is shut through Dec. 10 for planned miter gate repairs, prompting vessels
to detour through the Barkley Canal via Barkley Lock. The bypass has reportedly
added 1-2 days of travel time in each direction. The Corps will temporarily
resume service through Kentucky Lock on Nov. 25-28 to pass waiting vessels.
Despite
a reported conclusion of repair work at Wilson Lock on Nov. 11, delays
continued to be reported at the site. Most waits were reported in the 4-11 hour
range, while intermittent delays spiked above the 24-hour mark on Nov. 20-21.
Lock
6 on the Allegheny is expected to remain shut to navigation indefinitely due to
a damaged miter gate.
