U.S. Gulf:
Bayou Sorrel Lock is scheduled to shut to daytime
movements from April 21 through May 15,
blocking traffic daily from 7:00 a.m. to 6:00 p.m. Sources predicted 24-48 hour
delays.
Sources
reported a number of projects slowing navigation in the Port Allen Route for
the week. In addition to upcoming Bayou Sorrel Lock repairs, ongoing stoppages
at the Gross Tete Bridge limited navigation to just four hours a day through
May 17, from 10:00 a.m. to 12:00 p.m., and 10:00 p.m. to 12:00 a.m.
Towing restrictions in place at Port Allen Lock, the
result of guidewall damage suffered during a January barge collision, also
slowed movements on the Port Allen Route. West-moving tows with two barges or
more were required to utilize an assist vessel on all lockages, while locking
was available without assistance for westbound vessels with one barge or less
in tow. All eastbound traffic measuring longer than 650 feet was required to
use an assist vessel. Wait times for the week were noted in a wide 8-21 hour
range.
Harvey Lock was reported closed to navigation
through May 21 due to ongoing repairs to the nearby 4th Street
Bridge, prompting detours through Algiers Lock. The added traffic, along with
high water levels reported in the area, combined to push Algiers delays as high
as 48 hours for the week, with 32 tows reportedly queued to lock on April 13.
Restrictions
persisted at Algiers Lock, sources said, limiting unassisted tows with widths
above 60 feet to lengths of 600 feet. Vessels with tows narrower than 60 feet
were permitted up to 700 feet long, essentially restricting unassisted lockages
to four standard barges or two 30,000 mt tankers per turn. Longer tows were
possible with the use of an assist vessel, sources said. Most Algiers Lock
delays were reported in the 24-50 hour range for the week.
Due
to high water in the Gulf and lower Mississippi River, tow lengths were reduced
by 5-10 barges on travel above New Orleans. Tows are typically permitted up to
25 barges through the region.
River
levels were reported at a moderate-flood 38.35 feet at Baton Rouge, La., on
April 13. An NWS Flood Warning dated April 12 for the Mississippi River at
Donaldsonville, La., Baton Rouge, and Red River Landing, Miss., was slated to
expire on April 27. Storm systems moving through the Gulf and canals were
projected to impact movements on April 13-19.
Maintenance and repair operations concluded at
Colorado Lock on April 9, normalizing movements through the area. Industrial Lock delays were noted up to 48 hours for
the week, rising from 8-17 hours reported previously. Sources quoted Brazos
Lock passages up to 26.5 hours on April 11-12.
Mississippi River:
High water levels were exacerbated by weekend rains,
sources said, triggering towing restrictions at numerous locations on the
Mississippi River during the week.
On the upper river, sources described maximum tow
lengths capped at nine barges between St. Paul and Prairie du Chien, while
boats running from Prairie du Chien to St. Louis were limited to 12 barges per
tow.
Depths clocked at an action-stage 28.91 feet at St.
Louis prompted ongoing restrictions to Cairo, Ill., reducing barge counts by
five units. Additionally, daylight-hour restrictions were reported in place on
travel through bridges at St. Louis and Thebes, Ill.
Below Cairo, tows were reduced by 5-10 barges from
the typical 25-barge limit. Water levels at Vicksburg, Miss., were posted at a
minor-flood 44.65 feet and falling slowly on April 14, with forecasts
predicting a move below the 35-foot action stage on April 26-27. Tows were
limited to daytime-only movements through bridges at Memphis, Tenn., Vicksburg,
and Baton Rouge. The NWS posted a Flood Warning for Vicksburg and Natchez,
Miss., on April 13.
Overnight travel through the railroad bridge at the
upper river’s Mile 699 was reportedly unavailable for the week due to a
shortage of lock operators.
Lock 2 will see a number of daytime 4-12 hour
closures in July for miter gate installation. Daylight-hour shutdowns were
expected at Lock 25 in July and August for guidewall repairs. Delays for the
week were noted at five hours at Lock 18, while boats passing Lock 22 reported
eight-hour waits on April 14.
Illinois River:
Heavy weekend rains reversed a short-lived
resumption of lockages through Peoria Lock during the week, sources said.
Wickets remained down at LaGrange Lock.
Ohio River:
Meldahl
Lock primary chamber machinery repairs previously scheduled to run from April
12 through June 11 were delayed, sources said. Updated dates for the project
were expected to be announced soon. Vessels will pass through the secondary
chamber while work is underway, with waits expected.
The main chamber at Cannelton Lock is slated to
close from June 21 through Nov. 19. Tows will pass the site through the
secondary chamber, effecting considerable delays.
The
Markland Lock auxiliary chamber is projected to remain shut through Oct. 29 due
to cracks in the miter gate. Locking has remained available through the primary
chamber since the start of the shutdown in early 2020. The secondary chamber at
New Cumberland Lock is closed through June 10 for repairs and maintenance.
Sources reported lowered wickets at Olmsted Lock due
to high water, allowing movements through the nonlocking navigational pass.
On
the Tennessee River, the Corps announced a planned main chamber shutdown at
Wilson Lock for repairs, slated for May 4-13. Transit will remain available
through the secondary chamber. Wait times at Kentucky Lock were quoted up to 19
hours during the week.
Bio-acoustic
fish fence (BAFF) repair at the Cumberland River’s Cheatham Lock were
rescheduled for May 10 through July 15. As with the prior schedule, the Corps
is expected to plan three temporary openings during the closure to pass waiting
traffic.
Arkansas River:
Restrictions continued to be reported on the
Arkansas River due to elevated water levels, slashing maximum tow lengths from
12 barges to nine. The reductions were likely to persist into late April,
sources said.
David D. Terry Lock navigation is scheduled to be
completely unavailable from Aug. 27 through Sept. 9 for dewatering and repairs.
Ahead of the shutdown, intermittent delays are expected on Aug. 16-26.
