U.S. Gulf:
A sunken barge reported at Mile 236 in the West
Canal on Jan. 30 resulted in alternating one-way travel restrictions through
the site, sources said. Salvage operations scheduled to kick off on Feb. 1 were
projected to close the area to navigation until the clearance operation is
completed. Delays were noted in the 15-69 hour range for the week.
Sources
reported continued towing restrictions at Port Allen Lock after a barge
collided with the site’s guidewall in January, damaging the structure. Tows
traveling in the westbound direction with more than one barge were required to
use an assist vessel, while vessels locking without assistance were capped at
one barge per turn. Eastbound vessels longer than 650 feet were required to
lock with an assist vessel. Sources reported intermittent delays in the 6-19
hour range.
Length
restrictions were also ongoing through Algiers Lock, with tows greater than 60
feet in width limited to 600-foot lengths. Vessels with widths under 60 feet
were permitted 700-foot tows. The restrictions effectively limited lockages to
four dry barges or two 30,000 mt tankers per tow. Dolphin repair scheduled for
Feb. 22 will close the lock from 7:00 a.m. to 6:00 p.m., sources said.
Repairs
in progress at the Rigolets Bridge in the East Canal were reported limiting
access to the Pearl River to three openings per day. Vessels were permitted to
pass the 1930s-era structure daily at 5:30 a.m., 1:30 p.m., and 9:30 p.m.
through March 12.
Shippers
reported mostly good daytime travel conditions for the week, although seasonal
fog-related slowdowns continued to play a factor in overnight travel.
Bayou
Sorrel Lock waits were noted up to five hours, while Industrial Lock delays
were typically clocked at six hours or less. Boats transiting Bayou Boeuf Lock
reported 4-7 hour delays on Feb. 2, and Colorado Lock passages ran in the 5-7
hour range. Shippers reported sporadic Brazos Lock delays as high as 16 hours
during the week.
Mississippi River:
Sources noted revetment operations underway at Mile
306 limiting southbound travel during daytime hours. Northbound travel was
permitted on a case-by-case basis.
Auxiliary chamber maintenance at Lock 27 concluded
on Jan. 29, briefly normalizing movement through the site ahead of a planned
Feb. 1-18 primary chamber closure. Although substantial delays have been
predicted as the project continues, waits were noted topping out below 12 hours
for the week.
Upper Mississippi River travel is unavailable for the
winter navigation season. Upper river locks are set to resume operation as
early as March 15, starting with Locks 13-19, while Lock 25 could begin spring
lockages as soon as March 31, weather permitting.
Illinois River:
Lake Peoria ice coverage was reported up to three
inches thick on the upper pool, prompting strong recommendations for the use of
ice couplings through the early week. Extreme temperatures in the forecast for
the entirety of the Illinois Waterway were projected to trigger new ice coupling
requirements at all locks, with the exception of Brandon Road Lock. The updated
requirements were projected to kick in on Feb. 6.
Demolition of the Utica Bridge at Mile 229.6 on the
Illinois River remains on track for Feb. 11, sources noted. Transit through the
area is likely to be interrupted for at least 24 hours due to the event. The
project has been continually delayed from its original December schedule.
Wickets remained in the raised position at Peoria
Lock and LaGrange Lock due to reduced water levels, triggering delays of up to
six hours at both sites. Six-hour delays were also quoted on Marseilles Lock
travel.
Ohio River:
The
auxiliary chamber at Markland Lock is shut through Oct. 29 due to structural
damage to the chamber’s miter gate, sources said. The chamber was offline for
the majority of 2020, although tows have been able to pass through the lock’s
primary chamber.
The
Meldahl Lock main chamber is set to close to navigation on Feb. 1-11 for fill
valve repairs, sources said. The chamber will shut again on April 12 through
June 11 to conduct miter gate machinery repairs. Delays are expected during
both closures.
Smithland
Lock is scheduled to undergo consecutive shutdowns of the site’s two secondary
lock chambers for maintenance and repairs. The work is slated to run from Feb.
1 through approximately April 1, during which navigation will continue through
the main chamber. Sources are anticipating minimal delays.
The
secondary chamber at New Cumberland Lock is scheduled to go offline on March 8
through June 10. Passage is anticipated to remain available through the primary
chamber, limiting delays.
Greenup
Lock is scheduled to shut its main chamber on Feb. 11 through March 11 for
miter gate machinery repairs, pushed forward from the previous May 10-June 11
schedule. Transit will remain available via the smaller secondary chamber, with
lengthy delays expected, although sources warned of intermittent full-lock
shutdowns as well. Following the main chamber project, the site’s auxiliary
chamber will close on March 11 through April 11, with traffic continuing to
pass through the primary chamber.
Navigation
will be unavailable through the Cannelton Lock primary chamber on June 21
through Nov. 19, triggering delay predictions. Increased flows prompted Olmsted
Lock operators to lower wickets during the week, sources noted, allowing tows
to pass the site via the non-locking navigational pass.
On
the Tennessee River, Watts Bar Lock saw intermittent four-hour shutdowns daily
through Feb. 4. Sporadic Kentucky Lock delays were also noted at 4-9 hours for
the week, sources said.
The
Cumberland River’s Cheatham Lock will see a main chamber closure on April 12
through June 21. The Corps will open the site to pass waiting vessels four
times during the shutdown, remaining open three days on each occasion. The
opening windows remained unscheduled on Feb. 3, sources said.
Arkansas River:
Norrell Lock, located at Mile 10 on the Arkansas River,
closed to navigation at 6:00 a.m. on Feb. 2 for repair operations, effectively
blocking tows from entering and exiting the river. Movements were scheduled to
resume at 6:00 p.m. on Feb. 6.
