U.S. Gulf:
With water levels holding above the crucial 12-foot
mark, restrictions remained in effect at New Orleans during the week. The river
gauge was posted at 13.36 feet and holding on March 22. Forecasts predicted
levels to fall back to the 12-foot mark on April 4.
Calcasieu Lock on March 22 kicked off a period of
daytime travel shutdowns, limiting Monday through Thursday movements weekly
between 7:00 a.m. and 6:00 p.m. The project was scheduled to run through May
19, with significant delays expected.
Daylight-hour movements were unavailable through
Brazos Lock on weekdays due to ongoing lock maintenance. Navigation was
unavailable Monday through Friday, between 7:00 a.m. and 7:00 p.m. Delays were reported
up to nine hours during the week. Sources expected the closures to continue
into May.
A Bayou Sorrel Bridge repair project is slated to
limit daytime navigation through the lock until the end of May. Weekday
shutdowns were scheduled to run from 7:00 a.m. to 11:00 a.m., and from 1:00
p.m. through 5:00 p.m., with normal transit hours returning on weekends.
Weekday delays were also reported at Bayou Sorrel
Lock due to guidewall replacement work in effect through February 2023. Waits
were reported in the 24-48 hour range through the week.
Bayou Chene travel remained unavailable during
overnight hours due to floodgate construction. A Coast Guard notice described
the waterway as shut nightly between 7:00 p.m. and 7:00 a.m., while navigation
remained available during daytime hours, subject to a maximum 600 feet of
length and 54 feet of width. Configurations measuring wider than 54 feet were
required to utilize an assist vessel. Wait times were expected in the 6-12 hour
range.
Shoaling at Miles 113-116 of the Atchafalaya River
necessitated 10-foot draft limits through the area, according to Coast Guard
information. Additionally, tows were capped at a maximum 600 feet, while
lengths above 400 feet were advised to travel with an assist vessel. Widths
were allowed up to 70 feet. Tows could bypass the restrictions entirely by
detouring through the Port Allen Route.
Tows traveling through Algiers Lock without an
assist tug continued to be subject to size limits, effectively capping tows at
four dry barges or two 30,000 mt tankers per turn. Larger lockages remained
possible with assistance, however. Waits were quoted up to 15.5 hours for the
week.
Construction at the Belle Chasse Bridge was
projected to cause intermittent travel delays for up to 12 hours at a time. The
project is scheduled to conclude late this year.
Intermittent Port Allen Lock delays were quoted in
the 10-19 hour range for the week. Boats traveling through Industrial Lock
required up to 40 hours to pass, Corps data indicated. Bayou Boeuf Lock wait times
were observed up to seven hours.
Mississippi River:
Persistent high water levels on the lower
Mississippi River necessitated ongoing restrictions, effectively reducing both
maximum barge counts and navigation speeds, as well as forcing overnight stoppages
on downriver transit through a number of urban locations.
River levels were dropping at Memphis, Tenn., where
the river gauge was seen crossing below the area’s 28-foot action stage on
March 18. Vicksburg, Miss., levels, posted at an action-stage 41.62 feet and
falling slowly on March 22, were expected to remain above action stage through
at least April 5, while depths at Baton Rouge, La., were noted at a minor-flood
35.53 feet on March 22. The Baton Rouge gauge was predicted to fall out of
flood stage on March 25, but remain above action stage through the entirety of
the two-week forecast.
On the upper Mississippi River, Locks 1, 4-8, 12-13,
and 5A remained closed to navigation on March 22, later than the industry’s
previous March 17 tentative return to spring navigation. The locks were
expected to open imminently, as conditions allow. Sources continued to express
hope that barges could begin arriving in the St. Paul area by the end of the
month.
Wait times were noted up to nine hours for the week
at Mel Price Lock. Delays were reported at 4-6 hours through Lock 27 on March
21-22.
Illinois River:
A major repair and maintenance effort scheduled at
Brandon Road Lock will impact navigation from May 9 through Sept. 8, Corps
documents indicated. Travel will be confined to overnight hours and subject to
70-foot width restrictions between May 9 and Aug. 14, after which the lock will
undergo a complete shutdown from Aug. 15 through Sept. 4. Nighttime transit and
width restrictions will resume on Sept. 5-8, followed by a return to normal
operation on Sept. 9. Considerable delays are predicted throughout the project
schedule.
Marseilles Lock delays were noted up to 5.5 hours
during the week. Wickets were reported in the lowered position at both Peoria
Lock and LaGrange Lock, allowing tows to pass both sites via their nonlocking
navigational passes.
Ohio River:
Despite
elevated flows continuing throughout much of the Ohio River system, rapidly
improving conditions were noted to positively impact travel during the week.
Primary
chamber repairs at Emsworth Lock forced passage through the site’s auxiliary
chamber. Lockages were limited to a single barge per pass, resulting in wait
times in a reported 3-6 day range during the week, firming from 2-6 days noted
previously. The project is set to run through April 16.
Daylight-hour
navigation is unavailable at Cannelton Lock on Wednesdays and Thursdays through
May 26 due to a repair project that kicked off on Jan. 26. A proposed
subsequent maintenance and repair project would limit Cannelton Lock main
chamber availability from July 5 through Nov. 11, prompting vessels to transit
through the secondary chamber.
Maintenance
to the Dashields Lock main chamber scheduled for March 7-31 was noted routing
traffic through the site’s auxiliary chamber. Following the main chamber
project’s conclusion, the auxiliary chamber is scheduled to close for
maintenance on April 1-22. Corps data showed Dashields wait times up to 56
hours for the week.
Repairs
and maintenance scheduled for May 2 through June 22 at Belleville Lock is
projected to limit access to the site’s main chamber. Passage will continue to
be available through the auxiliary chamber while work is underway.
A
main chamber maintenance operation proposed to run from July 5 through Oct. 8
would require vessels transiting Hannibal Lock to use of the auxiliary chamber.
Wilson
Lock, located at the Tennessee River’s Mile 259.4, is undergoing main chamber
maintenance through April 28, forcing navigation through the secondary chamber.
The main chamber was reportedly open for use on March 18-23 to pass assembled
traffic, dropping delays down to the 18-30 hour range from recent reports of
5-8 days.
Most
Kentucky Lock delays were quoted in the 5-10 hour range, while a handful of
intermittent waits were observed in up to 14-18 hours. Wait times were
previously noted at seven hours.
On
the Cumberland River, southbound traffic was paused during the week at Mile 2
due to a sunken barge in the area. Normal navigation was expected to resume in
the week ahead.
Barkley
Lock was closed to daytime navigation on March 21-27 for planned Bio-Acoustic
Fish Fence (BAFF) maintenance and inspections. Detours were available via
Barkley Lock and Kentucky Lock.
Miter
gate machinery repairs proposed for Cheatham Lock would limit navigation
through the site between May 31 and Aug. 5. The Corps was expected to schedule
intermittent opening windows to limit vessel backlogs.
Arkansas
River:
A maintenance and repair
project in the works at Norrell Lock will block navigation daily between 7:00
a.m. and 7:00 p.m. for a series of 10-day chunks, scheduled through the end of
the year. The closures are slated for 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. 3-31,
2023.
