U.S. Gulf:
Weekday navigation through Bayou Boeuf Lock
continued to be limited to the hours between 7:00 p.m. and 7:00 a.m., with
24-hour availability on Saturdays and Sundays.
A Coast Guard posting noted the end of draft
restrictions in the Houma Navigational Canal during the week. Shoaling at Mile
7 of the waterway had previously required 11-foot maximum drafts at Miles 6-10.
Floodgate work at Bayou Chene restricted travel to 7:00
a.m. to 7:00 p.m. daily. Tows were limited to 600 feet of length, with an
assist tug required for strings larger than 54 feet wide. In addition, dive
operations were expected to cause intermittent shutdowns for up to 6-12 hours
at a stretch.
Towing restrictions remained in force at the
Atchafalaya River’s Mile 113-116, centered in the Morgan City area, due to
shoaling. Maximum drafts were limited to 10 feet, Coast Guard documents
indicated, while tows were capped at 600-foot lengths and 70-foot widths. Tow
lengths above 400 feet were strongly advised to utilize an assist tug. Vessels
were encouraged to bypass the restrictions via a detour through the Port Allen
Route.
Length and width restrictions remained in effect for
Algiers Lock travel, effectively capping unassisted movements to four standard
barges or two 30,000 mt tankers per turn. Larger lockages were possible when
accompanied by an assist vessel.
Belle Chasse Bridge construction was noted
triggering intermittent navigational shutdowns up to 12 hours at a time. The
bridge is located at Mile 3 in the West Canal.
Port Allen Lock wait times were noted in a general
8-12 hour range, while Corps data showed intermittent Bayou Sorrel Lock delays
falling in the 16-24 hour range. Sporadic Industrial Lock waits were quoted at
a wide 6-24 hours, and intermittent 24-36 hour delays were reported through the
Colorado Floodgates.
Mississippi River:
Low water conditions in the St. Louis area were
noted further tightening draft restrictions on the lower Mississippi River
during the week, with limits of 9.5-10 feet reported at various points along
the lower river.
Depths at St. Louis were observed at (-)0.08 feet on
Jan. 12, rising from (-)0.6 feet reported previously. Forecasts called for a
quick increase to 0.7 feet on Jan. 13, followed by a decline to (-)2.0 by Jan.
25.
Channel reinforcement work underway at Mile 642 on
the lower river is scheduled to run into late February. The project was likely
to delay southbound vessels up 12 hours through the area.
The
upper Mississippi River’s Locks 1-21 were reportedly shut for the winter
navigation season on Jan. 11. Lock 25, previously scheduled to close for
seasonal maintenance on Jan. 1-31, continued to pass tows during the week,
Corps data indicated, with wait times noted up to 5.5 hours. Lock 24 was also
closed to navigation for the week.
Lock reopenings for the spring season were scheduled
to begin on March 3 with Lock 15, followed by Locks 5 and 7 on March 11. Locks
5A, 8, and 10 were slated to resume lockages on March 17, while Lock 4 was set
to reopen on March 21, conditions permitting.
Illinois River:
Worsening ice conditions on the Illinois Waterway impacted
river travel during the week, with LaGrange Lock and Peoria Lock seeing the
worst of it. Wait times at LaGrange were clocked up to four days on Jan. 11.
Temperatures were expected to improve in the short-term, although forecasts
suggested significant slowdowns heading deeper into January.
Ice couplings were required through all Illinois
River Locks during the week. Wickets were noted in the raised position at both
Peoria Lock and LaGrange Lock.
A repair and maintenance project at Brandon Road
Lock is scheduled to run from May 9 through Sept. 8, with major impacts to
navigation expected. The work will block daytime travel from May 9 through Aug.
14, followed by a complete lock shutdown between Aug. 15 and Sept. 4.
Daylight-hour closures at Brandon Road Lock will
resume on Sept. 5-8, followed by a planned reopening on Sept. 9. A 70-foot
width limit will be in effect while work is underway. Corps data estimated delays
as high as 12 hours for the week.
Ohio River:
Elevated water levels resulted in towing
restrictions and delays on the Ohio River during the week.
The
secondary chamber at Dashields Lock was reportedly closed to navigation due to
an underwater obstruction interfering with operation of the lower miter gate.
Lockages remained possible through the primary chamber, however.
A proposed Hannibal Lock main chamber repair project
is likely to impact travel through the site between July 5 and Oct. 8.
Cannelton Lock is also facing a proposed shutdown, set to run from July 5
through Nov. 11, forcing lockages through the auxiliary chamber.
On the Tennessee River, main chamber repairs scheduled for Feb. 23 through April
28 at Wilson Lock are anticipated to trigger detours through the site’s
secondary chamber, likely resulting in delays. The main chamber is tentatively
scheduled to open for a single window during the project, on March 18-23.
Kentucky
Lock waits were quoted up to five hours for the week. Wilson Lock delays peaked
at 5.5 hours on Jan. 9, falling from 22 hours reported one week earlier.
Barkley
Lock, located on the Cumberland River, will experience daily shutdowns between
6:00 a.m. and 6:00 p.m. on Jan. 15-30 due to planned maintenance to the site’s
bio-acoustic fish fence (BAFF) system. Work proposed at Cheatham Lock will
likely result in navigation disruptions between May 16 and Aug. 4.
Navigation
through Lock 6 on the Allegheny River remained unavailable due to a damaged
miter gate anchorage.
