below five hours on Sept. 12.
Work at Colorado Lock concluded on Sept. 9 after
blocking navigation from 7:00 a.m. to 5:00 p.m., Monday through Friday. Wait
times ran up to nine hours on Sept. 12.
Guidewall
replacement efforts in progress since Aug. 1 at Bayou Sorrel Lock were reported
to intermittently block Monday-through-Friday travel during daylight hours. The
project was anticipated to continue through February 2023. Minimal delays were
reported during the week.
Dredging to correct extensive shoaling at Miles 113-117 of the Atchafalaya River, in the Morgan City, La., area, was reported in progress through Sept. 15. While the effort is underway drafts are reportedly limited to 10 feet, while lengths and widths are capped at 600 feet and 55 feet, respectively. Tows with lengths above 400 feet are required to utilize an assist vessel, according to a Coast Guard safety bulletin. Captains were also required to check in with the VTS Berwick Bay at Mile 110 prior to arrival in the area.
Following the revelation of potentially hazardous
underwater pipes during a recent hydrograph of the Atchafalaya River,
navigation was rendered temporarily unavailable through Little Island Pass,
Middle Island Pass, and Riverside Pass. Tows could bypass the river’s
restrictions by detouring through the Port Allen Route.
Length and width restrictions persisted on
unassisted lockages through Algiers Lock,
limiting tows to four standard barges or two 30,000 mt tankers per pass. Larger
turns were possible when traveling with an assist boat. Delays were heard up to
five hours during the week.
A construction project underway at Belle Chasse Bridge through the end of the year was
expected to trigger intermittent shutdowns lasting up to 12 hours at a time.
Port Allen Lock waits were routinely quoted in the
4-10 hour range through the week.
Mississippi River:
Reduced depths on the lower Mississippi River
continued to impact towing capacity during the week. Maximum southbound drafts
persisted at 11.5 feet between Cairo, Ill., and Rosedale, Miss., while tows
traveling northbound were limited to a reported 10.5 feet of draft. Maximum tow
lengths were also reportedly reduced by 10-15% from typical levels.
The river gauge at St. Louis was posted at 1.80 feet
and falling on Sept. 14, down from 2.06 feet reported one week earlier. Levels
were expected to fall below the 0.00-foot mark on Sept. 21, later than the
prior Sept. 12 forecast.

blocking most southbound travel daily from 7:00 a.m. to 5:00 p.m.
I-10 bridge repairs in progress at Miles 228-230
triggered a safety advisory for all boats passing through the area. The
operation, slated to run 24 hours per day through June 30, 2023, was expected
to prompt intermittent navigation stoppages as well.
Old River Lock, located at the lower river’s Mile 305,

project is underway.
Loading cutoffs for NOLA-departing barges destined

invasive carp deterrent system, and will run weekly through Oct. 7.
Wickets remained in the raised position at both Peoria Lock and LaGrange Lock during the week,
requiring tows to lock through both locations. Sporadic 4-10 hour delays were
reported at LaGrange.
Ohio River:
The primary chamber at Cannelton Lock was reported
shut for repairs and maintenance through Nov. 11, forcing passes solely through
the site’s secondary chamber. With most tows requiring at least two passes to
clear the lock, wait times were observed at 10-24 hours through the week,
falling from 24-36 hours reported previously.
Repairs in progress to the main chamber quoin and
miter gate at Hannibal Lock required a complete shutdown of the chamber through
Oct. 8. Transit was available through the auxiliary chamber, with minimal
delays reported through the week. Intermittent 6.5-hour wait times were noted
at Greenup Lock.
