U.S. Gulf:
Fleet
and towing restrictions remained in effect in the New Orleans area for the week
due to persistent high water levels.
The
river gauge at New Orleans was reported at 12.44 feet and falling slowly on
April 4. Forecasts showed the gauge receding below the 12-foot mark on April
10, likely marking an end to regional restrictions.
Daytime
travel was reported unavailable Monday through Thursday at Calcasieu Lock,
through May 19. Closures at the site were expected to run from 7:00 a.m. to
6:00 p.m.
Located at Mile 401 in the West Canal, Brazos Lock
was reported shutting to traffic Monday through Friday, 7:00 a.m. to 5:00 p.m.,
through at least mid-April. Corps data revealed delays up to 16 hours for the
week.
An ongoing repair project at the Bayou Sorrel Bridge
prompted daily marine travel shutdowns between 7:00 a.m. and 11:00 a.m., and
again from 1:00 p.m. to 5:00 p.m., Monday through Friday. Work at the site was
projected to continue into late May.
Guidewall construction operations at Bayou Sorrel
Lock, expected to persist through late May, were noted limiting site access
from 6:30 a.m. to 5:00 p.m. on weekdays. Wait times were generally reported in
the 20-44 hour range, rising from 20-32 hours in the prior week.
Bayou Chene navigation was limited to the hours of
7:00 a.m. through 7:00 p.m. daily due to ongoing floodgate construction, according
to a Coast Guard posting. Tows were capped at 600 feet of length, while an
assist boat was required for tows measuring wider than 54 feet. Intermittent
daylight-hour shutdowns were also anticipated due to dive operations, with 6-12
hour delays expected.
Shoaling noted at Miles 113-116 in the Atchafalaya
River necessitated ongoing draft restrictions through the Morgan City, La.,
area, a Coast Guard bulletin indicated. Maximum drafts were noted at 10 feet,
while tow lengths were capped at 600 feet. Vessel widths were permitted up to
70 feet, while strings running longer than 400 feet were encouraged to use an
assist vessel. Captains could sidestep the restrictions by detouring through
the Port Allen Route.
Length and width restrictions continued on travel
through Algiers Lock, capping unassisted lockages at four standard barges or
two 30,000 mt tankers per pass. Tows passing the site with an assist tug were
permitted to lock larger configurations, however. Waits were reported in a wide
11-26 hour range, with 22 vessels in the locking queue on April 4.
The ongoing Belle Chasse Bridge construction
project, scheduled to run into late 2022, was heard to result in intermittent
transit stoppages lasting up to 12 hours at a time.
Wait times at Port Allen Lock were reported up to six hours for the week. Industrial Lock delays swelled to the 24-48 hour range, while boats passing Calcasieu lock were delayed up to eight hours.
Mississippi River:
Persistent high-water conditions left towing
restrictions in place for another week on the lower Mississippi River, sources
said. Reduced barge counts were reportedly in effect, while larger southbound
tows were limited to daylight-only travel through some urban areas, determined
on a case-by-case basis.
Levels at the Vicksburg, Miss., river gauge were
observed at an action-stage 38.63 feet and falling slowly on April 6. Forecasts
called for river levels to fall out of action stage on April 14.
The Baton Rouge, La., gauge was noted at an
action-stage 33.4 feet on April 6, after cresting shy of the 35-foot
minor-flood stage at 34.8 feet on March 31. Projections showed Baton Rouge
exiting restricted territory on April 16. A flood warning in effect for the
area was slated to expire on April 15.
Illinois River:
Heavy rains and elevated river levels were noted
impacting freight operations on the Illinois Waterway during the week.
Marseilles Lock delays jumped to the 5-11 hour range as a result, while
slowdowns were heard spreading downriver on April 6, prompting navigation delays
and travel slowdowns.
The river gauge at Ottawa, Ill., showed water levels
bouncing in and out of action stage during the week. Depths were noted at
460.58 feet on April 6, just shy of the 461-foot action-stage threshold, but
were expected to crest at 461.5 feet on April 7.
The Peoria gauge was quoted at a minor-flood 18.36
feet and rising on April 6. Following a 19.0-foot crest expected on April 9-10,
the gauge was projected to remain above the minor-flood limit through at least
April 13.
Repairs and maintenance scheduled for Brandon Road
Lock from May 9 through Sept. 8 will effect wide-ranging impacts to navigation.
Overnight-only travel will be in place between May 9 and Aug. 14, followed by a
complete lock shutdown on Aug. 15 through Sept. 4. Nighttime navigation will
return on Sept. 5-8, with the lock scheduled to resume normal operation on
Sept. 9. A 70-foot width limit will be in effect on all navigation through the
site while work is in progress.
Wickets remained in the lowered position at Peoria Lock
and LaGrange Lock, allowing boats to pass both locations without locking.
Lockport Lock delays were noted up to six hours for the week. Starved Rock
waits were reported in the 4-9 hour range.
Ohio River:
Primary
lock chamber repairs in progress at Emsworth Lock since Feb. 22 limited vessels
to the auxiliary chamber, with tows capped at one barge per lockage. As a
result, delays were recorded in a wide 3-6 day range for the week, below the 4-6
days reported previously. The project is scheduled to conclude on April 16.
The
Dashields Lock main chamber was expected to exit a repair and maintenance
shutdown on April 8, ending a bout of redirection through the site’s auxiliary
chamber. Waits were noted at 40-65 hours on April 6, falling from 2-4 days
reported previously.
Daylight-only travel limitations are in effect at Cannelton Lock on Wednesdays and Thursdays through May
26. An additional Cannelton Lock
shutdown proposed for July 5 through Nov. 11 would require detours through the
secondary chamber.
Belleville
Lock is slated to undergo a main chamber shutdown from May 2 through June 22
for repairs and maintenance. Traffic is expected to pass through the secondary
chamber while the project is underway.
A proposed main chamber shutdown at Hannibal Lock
would impact transit through the lock from July 5 through Oct. 8, according to
a Corps notice.
The Tennessee River’s Wilson Lock remains in the
midst of a main chamber shutdown, forcing lengthy detours through the site’s
auxiliary chamber. Wait times, expected
to persist through the project’s scheduled April 28 end date, were observed in
the 4-5 day range for the week, with some predicting an increase to seven days
or more as the project moves closer to completion.
Kentucky
Lock waits were quoted at 4-9 hours for the week. Kentucky Lock is engaged in a
long-term construction project slated to run through 2024.
Cheatham
Lock miter gate machinery repairs booked for May 16 through Aug. 5 are expected
to see substantial delays. Work at the site will run on an 11-days-on,
three-days-off schedule, effectively establishing a single three-day opening
window per two-week period.
Arkansas River:
Norrell Lock maintenance and repairs will block
daylight-hour travel through the lock on June 1-11; June 22-July 21; Aug. 1-10;
Aug. 21-Sept. 21; Sept. 3-Oct. 9; Oct. 20-Nov. 18; Nov. 29-Dec. 23; and Jan.
