U.S. Gulf:
Bayou Sorrel Lock was shut to daytime navigation for
the week through April 7, sources said, blocking movements daily from 7:00 a.m.
to 6:00 p.m. due to repairs. Additional daylight-hour shutdowns were scheduled for
April 21 through May 15, with sources expecting delays in the 24-48 hour range.
Repairs to the Gross Tete Bridge, located at Mile 36
in the Port Allen Route, were noted blocking navigation daily from 12:00 a.m.
to 10:00 a.m., and 12:00 p.m. to 10:00 p.m. The project is scheduled to run
through May 15.
Harvey Lock closed to navigation on April 5 due to
scheduled repairs to the nearby 4th Street Bridge. Traffic is
expected to detour through Algiers Lock until May 21 while Harvey is shut,
increasing travel times and delays at Algiers.
Maintenance and repairs at Colorado Lock were
extended through April 9, sources said, prolonging a spate of daytime travel
closures that began in late March. Intermittent delays were noted up to nine
hours for the week, falling from 15 hours in the prior report.
Efforts to repair damage to the Leland Bowman Lock
west gate blocked daytime traffic on April 5-7. Additional work necessary to
complete the repairs will likely slow movements at the lock through the
short-term, sources said.
Guidewall
damage suffered at Port Allen Lock in a January barge collision continued to
necessitate towing restrictions. Westbound vessels with tow-lengths greater
than one barge were required to utilize an assist vessel, while west-moving
boats with one or zero barges were allowed to pass unassisted. Tows traveling
eastward with lengths greater than 650 feet were required to use an assist
vessel. Waits were quoted up to 10.5 hours for the week.
Ongoing
size restrictions remained in effect at Algiers Lock for the week. Unassisted
tows above 60 feet wide were capped at 600-foot lengths, while tows with widths
below 60 feet were permitted lengths up to 700 feet. The limitations capped
unassisted tows at four standard barges or two 30,000 mt tankers per turn,
although longer strings were possible with the use of an assist vessel. Wait times through the lock were posted up to
27.5 hours for the week, with 21 vessels counted in the queue on April 6.
High
water conditions continued to restrict towing above New Orleans during the
week, reducing barge counts by 5-10 units from the region’s typical 25-barge
maximum.
Depths
at Baton Rouge, La., were reported at a minor-flood 37.77 feet and rising on
April 6. Forecasts called for the gauge to crest at a moderate-flood 38.0 feet
on April 6-7 before slowly tapering off. A flood warning dated April 6 for the
Mississippi River at Red River Landing was slated to remain in effect through
April 24.
Most
Industrial Lock waits were quoted in the 8-17 hour range for the week, although
sources noted sporadic delays spiking above 25 hours. Bayou Boeuf crossings
were noted up to 12 hours, while boats transiting Brazos Lock waited up to 47
hours to pass.
Mississippi River:
High water levels continued to trigger towing and
travel restrictions on movements south of Cairo, Ill. Barge counts were capped
at 15-20 barges, down from 25, while daylight-only travel restrictions were
reported in place through bridges in the Vicksburg, Miss., and Baton Rouge
areas.
Levels at Vicksburg were clocked at a minor-flood
44.85 feet and holding on April 7, with depths projected to remain above flood
stage through at least April 15-16.
High water concerns on the lower Mississippi River
led to a shortage of fleet space at Osceola, Ark., located at Miles 781-786.
Requests for acceptance to the fleet would be considered, sources said,
although many tows were expected to be turned away.
Transports remained cut by five barges between St.
Louis and Cairo despite improving depths at St. Louis. Sources expected these
restrictions to have a shorter shelf life than those farther downriver,
although no date for a return to normal operation was reported as of April 7.
Lock 2 was projected to undergo a series of 4-12
hour daytime travel shutdowns in July for miter gate installation. Dates for
the work were unavailable on April 7. Lock 25 is also expected to see
daylight-hour closures in July and August for guidewall repairs.
Intermittent 5-6 delays were reported at Locks 14,
21, and 24 during the week.
Illinois River:
Sources said Brandon Road Lock was closed to
navigation from 6:00 a.m. to 3:00 p.m. on April 6 for emergency repairs.
Wickets were reported down at both Peoria Lock and
LaGrange Lock for the week, allowing vessels to pass the sites without locking.
Wait times were noted up to six hours at Dresden Island Lock.
Ohio River:
The
secondary chamber at Greenup Lock was scheduled to return from maintenance and
repairs on April 11, ending an operation that began on March 24.
Meldahl
Lock primary chamber is slated to shut from April 12 to June 11 for miter gate
machinery repairs. Traffic is scheduled to pass through the 600-foot secondary chamber
while work is underway, with delays predicted.
The
Cannelton Lock primary chamber is set to close to navigation entirely from June
21 through Nov. 19. Tows will detour through the smaller auxiliary chamber,
sources said, with extensive delays predicted.
Markland
Lock’s auxiliary chamber was projected to remain offline through at least Oct.
29 due to miter gate structural damage. Tows were reported passing with minimal
delay through the main chamber.
The
New Cumberland Lock auxiliary chamber was closed to navigation on March 8. Work
on the chamber is projected to run through June 10. Auxiliary chamber work
concluded at Smithland Lock on April 1, normalizing travel through the site.
With wickets remaining in the lowered position at
Olmsted Lock due to high water, tows passed the area via the nonlocking
navigational pass.
Falling
water levels on the Tennessee River were projected to allow a return to normal
navigation as early as April 7-8, sources said. Shippers were running
daylight-only in the prior week due to high water and fast flows. Intermittent
Kentucky Lock waits were noted up to eight hours for the week.
The
Cumberland River’s Cheatham Lock will halt main chamber navigation from April
12 through June 3 for bio-acoustic fish fence (BAFF) repair. The Corps will
temporarily reopen the lock on April 23-26, May 7-10, and May 21-24 to pass any
assembled backlog. Barkley Lock was noted concluding BAFF repairs on April 2.
Arkansas River:
High water continued to limit towing on the Arkansas
River for the week, with sources noting maximum barge counts cut to nine units
from the typical 12. Pickup and dropoff delays resulting from the restrictions
were likely to persist into late April, sources said.
David D. Terry Lock was scheduled to shut for
dewatering and repairs from Aug. 27 through Sept. 9. Travel will see sporadic
interruptions in advance of the shutdown, on Aug. 16-26.
