U.S. Gulf and Atlantic:
Travel through the West Canal remained unavailable
at Miles 21-33 due to shoaling and debris caused by Hurricane Ida. Most
through-traffic was bypassing the West Canal entirely, running from the New
Orleans area to Houston by way of the Port Allen Route. Work to reestablish
navigation was projected to run through the end of the month, adding 1-2 days
of travel time in each direction.
Bayou Lafourche was shut between Lockport and the
West Canal due to multiple vessels blocking the channel, as well as ongoing
hurricane-related cleanup efforts.
Floodgate construction activities left navigation
through Bayou Chene unavailable nightly between 7:00 p.m. and 7:00 a.m. until
further notice. In addition, tows were limited to 600-foot lengths, while barge
configurations measuring above 54 feet wide were required to utilize an assist
vessel on all movements through the waterway. Sporadic shutdowns of the entire
waterway were also possible, with resulting wait times predicted in the 6-12
hour range.
Ten-foot draft limits remained in effect at Miles
113-116 in the Atchafalaya River in the Morgan City area, due both to extensive
shoaling and reduced channel widths. Size restrictions were also in place, with
tows limited to 600-foot lengths and 70-foot widths, while strings measuring
longer than 400 feet were requested to use an assist boat.
The Coast Guard “highly recommended” that vessels
bypass the area via the designated Port Allen Route alternative. With 39 tows
counted in line to lock on Oct. 19, delays were quoted in a wide 50-75 hour
range, or approximately 2-4 days.
Unassisted movements continued to face size
restrictions through Algiers Lock, with tows generally capped at four standard
barges or two 30,000 mt tankers. Larger tows remained possible when accompanied
by an assist tug, however.
Warnings of intermittent navigational shutdowns were
heard through the Belle Chasse Bridge, located at the West Canal’s Mile 3, due
to construction slated to run through late 2022. Delays were anticipated up to
12 hours.
Bayou Boeuf Lock was reported open for navigation
between 7:00 p.m. and 7:00 a.m. on Monday through Friday. Locking returned to
24-hour availability on Saturdays and Sundays.
Intermittent Industrial Lock delays were noted in a wide 5-27 hour range for the
week, while Colorado Lock wait times
were quoted up to 19 hours through the site’s eastern lock, and up to 29 hours
through its western lock.
Mississippi River:
Rock-laying operations that kicked off on Oct. 20 at
the lower Mississippi River’s Mile 671 were likely to close the area to
southbound navigation from 7:00 a.m. to 6:00 p.m. daily. The project was
scheduled to run for about a week.
The Dredge Hurley was working at Mile 293
again during the week, but the operation caused no navigational issues.
Early seasonal shutdown dates for locks located on
the upper Mississippi translated to quickly closing release window on barges
loading from NOLA. Barges with final destinations located on the lower portion
of the upper river were typically noted to carry final release dates in the
last week of October. Material departing for terminals located at Iowa or above
was generally believed to carry a first-half October cutoff.
Locks 5A, 8, and 10 were slated to close to winter
navigation on Nov. 28, followed by Lock 4, 5, and 7 on Dec. 6. Lock 15 was
expected to shut on Jan. 1 following an auxiliary chamber closure running
through Dec. 1. Lock 24 will halt seasonal movements on Jan. 1-31.
Locks 5 and 7 are tentatively due to reopen on March
11, followed by Locks 5A, 8, and 10 on March 17. Lock 15 will return to service
on March 3, while Lock 4 will resume passing tows on March 21.
Lock 27 delays were noted up to 12 hours for the
week.
Illinois River:
Low water levels on the Illinois Waterway left
wickets in the raised position for another week at Peoria Lock and LaGrange
Lock.
Dresden Island Lock delays stretched to six hours or
more during the week. Boats passing Marseilles Lock were subject to wait times
up to 4-6 hours, while intermittent 5-8 hour waits were noted through Starved
Rock Lock.
Ohio River:
Main
chamber maintenance underway at Cannelton Lock was scheduled to necessitate
detours through the auxiliary chamber until Nov. 19. A planned auxiliary
chamber shutdown on Nov. 1-19 could precipitate intermittent full-lock
shutdowns.
The Montgomery Lock primary chamber was expected to
shut to navigation on Oct. 18, with work running through Dec. 17. Delays were generally expected to snowball as the
project runs on.
The
main chamber at Hannibal Lock was scheduled to return to normal operation on
Oct. 29, ending a period of secondary lock-only navigation. Waits were reported
up to six hours on Oct. 20.
Operation
of the Dashields Lock auxiliary lock chamber continued to be hindered by an
underwater obstruction blocking the chamber’s lower miter gate. No timeline was
available on Oct. 20 for a return to normal use.
The
Willow Island Lock main chamber is shut for the entire month of October, with
delays expected. Navigation was available through the secondary chamber, with
minimal delays reported.
The
Markland Lock secondary chamber, which has been shut since first-half 2020 due
to structural cracks in the miter gate, was tentatively projected to reopen in
late October. Ongoing maintenance at Olmsted Lock was noted pushing delays to as
high as 15 hours for the week.
On
the Tennessee River, main chamber repairs underway since Oct. 12 were projected
to conclude on Oct. 23, with tows passing through the secondary chamber during
the interim. Most delays were reported under six hours, while intermittent
waits spiked to nearly 20 hours on Oct. 19-20.
Wilson
Lock was passing vessels one way at a time during the week, with southbound
tows locking during daytime hours only. Northbound vessels were allowed to pass
overnight. Delays through the site were generally quoted up to 15 hours for the
week.
The
Corps announced a planned Kentucky Lock closure from Nov. 1 through Dec. 10. A
single four-day reopening window, tentatively scheduled for Nov. 25-28, will
pass waiting traffic. Boats passing Kentucky Lock reported waits in the 4-11
hour range for the week.
The
Monongahela River’s Lock 2 main chamber returned from repairs and maintenance
on Oct. 15, ending a period of secondary chamber-only navigation that started
on Sept. 13.
Lock
6 on the Allegheny River, will remain closed to navigation indefinitely due to
a damaged miter gate.
Arkansas River:
Intermittent daytime navigation shutdowns were
reported at Joe Hardin Lock on Oct. 19-21. Emmett Sanders Lock was scheduled to
undergo sporadic shutdowns between 7:00 a.m. and 6:00 p.m. on Oct. 26-28.
