U.S. Gulf:
Bayou Boeuf Lock was reportedly available for
weekday navigation between 7:00 p.m. and 7:00 a.m. only. Vessels were heard
returning to a 24-hour schedule on Saturdays and Sundays.
Floodgate construction underway at Bayou Chene
restricted travel to between the hours of 7:00 p.m. and 7:00 a.m. until further
notice. Tows were capped at 600 feet of length, while strings measuring wider
than 54 feet were mandated to use an assist vessel on all movements. In
addition, intermittent dive operations were projected to trigger complete
shutdowns of the area for up to 6-12 hours at a stretch.
Towing restrictions continued through Miles 113-116
in the Atchafalaya River, the Coast Guard reported. Localized in the Morgan
City area, drafts were reportedly limited to 10 feet due to extensive shoaling,
with tows limited to 600-foot lengths and 70 feet of width. Tows measuring
longer than 400 feet were advised to use an assist boat. Vessels were
recommended to detour through the Port Allen Route in order to bypass the
restrictions.
Vessels traveling through Algiers Lock also faced
length and width restrictions, effectively capping unassisted lockages to four
standard barges or two 30,000 mt tankers per turn. Larger tows were possible
when accompanied by an assist vessel, however.
A long-term construction effort underway at the
Belle Chasse Bridge was expected to trigger intermittent navigational shutdowns
through late 2022, with delays predicted up to 12 hours at a time. The bridge
is located near Mile 3 in the West Canal.
Port Allen Lock delays
were reported up to 28 hours for the week, with 25 tows counted in line to lock on Nov. 16. Vessels passing
Industrial Lock faced wait times up to 24.5 hours, while intermittent Brazos
Lock waits were noted up to 13 hours.
Mississippi River:
Revetment activities were noted restricting
southbound travel at Miles 343-346 on the lower Mississippi River for the week.
Tows moving downriver were limited to 20-25 barges during daylight hours,
between 6:00 a.m. and 7:00 p.m., triggering lengthy delays. The projected was
anticipated to run through Dec. 1.
Rock-laying operations set to kick off on Dec. 1
will trigger intermittent daylight-hour navigation shutdowns at Mile 595.
Expected to impact all movements through the area, the project was tentatively
scheduled through Dec. 15.
Lock 5A, Lock 8, and Lock 10 were schedule to shut
for the winter navigation season on Nov. 28, with Locks 4, 5, and 7 due to
follow on Dec. 6. Lock 15 has a projected Jan. 1 shutdown date for the season,
while Lock 24 was due to halt lockages for winter maintenance on Jan. 1-31.
Following Lock 24’s return on Jan. 31, Lock 15 was
expected to reopen on March 3. Locks 5 and 7 were due to resume operation for
the spring season on March 11, preceding a planned March 17 return to service
for Locks 5A, 8, and 10. Lock 4 is due to reopen on March 21.
Lock 25 delays were noted up to five hours for the
week. Intermittent Mel Price Lock wait times were noted in the 5-11 hour range.
Illinois River:
The Corps announced an extensive repair and
maintenance project at Brandon Road Lock, set to begin on May 9, 2022.
The plan will see a daytime travel shutdown in place
between May 9 and Aug. 14, followed by total lock closure running from Aug. 15
through Sept. 4. Daytime stoppages will resume on Sept. 5-8, followed by a
return to normal operation on Sept. 9. A 70-foot width limit is expected on all
lockages while the project is underway.
Wickets reportedly remained in the lowered position
at both LaGrange Lock and Peoria Lock for the week, allowing tows to transit
through the navigational pass.
Ohio River:
A prolonged bout of main chamber maintenance at
Cannelton Lock, underway since June 21, was scheduled to conclude on Nov. 19.
Adding to the restrictions, maintenance operations were also reported at the site’s
secondary chamber on Nov. 1-19.
The Montgomery Lock primary chamber is reportedly shut
through Dec. 22 for planned maintenance and repairs. With tows resigned to
locking one barge at a time through the secondary chamber, delays reportedly
swelled to 3-5 days in each direction, an increase from 41 hours in the prior
report.
Main
chamber work at Hannibal Lock, previously set to wrap up on Oct. 29, was
extended through Dec. 10, prompting detours through the site’s smaller
auxiliary chamber.
Use
of the Dashields Lock auxiliary chamber remained unavailable during the week
due to an underwater obstruction blocking the chamber’s lower miter gate since
October. Passage was possible via the main chamber, with minimal delays
expected.
On
the Tennessee River, Kentucky Lock was reportedly shut through Nov. 24 for
planned repairs. The Corps is scheduled to pass waiting vessels on Nov. 25-28,
followed by a second total shutdown between Nov. 29 and Dec. 10. Tows were
suggested to utilize Barkley Lock and the Barkley Canal as an alternate route
while the project is underway.
Wilson
Lock was noted returning from repairs on Nov. 11, ending a spate of staggered
one-way operation. Southbound tows had been passing the site during daylight
hours, while upriver-bound vessels were traveling overnight. Despite the return
to operation, delays were reported up to 26 hours during the week, rising from
19 hours in the prior report.
Passage
through the Allegheny River’s Lock 6 remained unavailable for the week due to
miter gate damage.
