SECTION I - SPECIAL NOTICES

This section contains information of special concern to the Mariner.

  

U.S. COAST GUARD NAVIGATION CENTER TO TRANSITION THE NAVIGATION CENTER WEBSITE

The U.S. Coast Guard Navigation Center is going to transition the Navigation Center website to a new, enhanced version in the first quarter of 2022. As part of this transition, URLs will be updated across the site including URLs linked to PDFs. Therefore, once the transition is complete, legacy site URLS will no longer function, including bookmarked URLs and URLs used in automatic downloading of data and/or products. Outdated URLs will automatically redirect to the home page of the site, and from there you will be able to easily navigate to your preferred page.

Below are a few of the “old”/new URL pairs listed for your convenience. Please note that the new URLs will not be active until we launch the new website. Of course, once it is launched, the new URLs will be available for re-bookmarking. As a reminder, these are top level URLs that may contain additional links that you use. This notice will be updated when the final launch date is determined, and another notice will be issued to notify you when the site goes live. Questions/concerns may be directed to the NAVCENWebTEAM@uscg.mil.

GREEN RIVER

 

MILE 9.1 - CHANNEL CONDITION/L/D CLOSURE

High water conditions reportedly exist at L/D 1, in the vicinity of Mile 9.1. L/D 1 has ceased locking operations due to high water with an upper gauge reading above 25.9 feet. Mariners should contact the lock operator to determine if it is safe to navigate over the weir.

 

OHIO RIVER

 

MILE 3.6 - TEMPORARY LIGHTED DANGER BUOYS

Mascaro Construction Co., LP., has installed 4 Temporary Lighted Danger Buoys with White flash characteristic Fl 2.5s, to mark a turbidity curtain around the perimeter of the construction area located at the Allegheny County Sanitary Authority (ALCOSAN), in the vicinity of Mile 3.6, RDB. The Temporary Lighted Danger Buoys were installed in the following approximate positions:

  • 40-28-42.82N 080-02-51.39W,
  • 40-28-47.97N 080-02-55.63W,
  • 40-28-55.90N 080-03-03.99W and
  • 40-29-00.91N 080-03-09.91W.

Any questions, inquiries or navigation safety concerns, should be directed to Mascaro Construction, Mr. Steve Senchesen, via telephone at (412) 321-4901 or email to ssenchesen@mascaroconstruction.com, or you may contact U.S. Coast Guard Sector Ohio Valley at (502) 779-5422 or via email at: STL-PF-SECOHVCommandCenter@uscg.mil. Mariners are advised to exercise caution in this vicinity and to completely avoid navigating outside of the navigable channel in the area.

 

MILE 532.0 - CHANNEL CONDITIONS

High water conditions have been reported at Markland L/D in the vicinity of Mile 532.0. Mariners are advised to exercise caution due to the hazardous conditions associated with strong currents, increased drift and severe outdrafts. Mariners are advised to consider horsepower capability and tow size. Fleet operators should regularly check their fleets and immediately report barge breakaways to the U.S. Coast Guard. If not preparing or completing locking, mariners are requested to leave the mooring cells immediately, leaving the locking chamber on the LDB, open for the next vessel in the lock queue, to allow them a better position to approach the lock. Mariners may contact the Markland L/D at (859) 567-7661, or the U.S. Coast Guard Sector Ohio Valley at (800) 253-7465, for additional information.

 

MILE 593.0 - MILE 606.8 - VTS ACTIVATION

The Vessel Traffic Service (VTS) Louisville, Kentucky has been activated. This system extends from Mile 593.0 to Mile 606.8, and will remain in effect while the McAlpine L/D, Upper Gauge reads 13.0 feet and above. Operating procedures and instructions to mariners are described in Title 33 Code of Federal Regulations Part 161. Mariners are urged to exercise caution in the area.

 

MILE 606.8 - L/D CLOSURE

On February 9, 2022, for 8-hours, the McAlpine L/D (south 1,200-foot chamber), in the vicinity of Mile 606.8, will be closed for repairs.

 

MILE 939.9 - CHANNEL CONDITION – UPDATE

Due to the rising river elevations, the navigation lane in the vicinity of Mile 939.9, the navigation lane over the bear traps and fixed weir, on the LDB, will open to navigation traffic and will remain open until the Paducah Gauge is at or below 30.0 feet. The navigation lane will be marked with electronic buoys (AIS aids to navigation). Mariners are urged to exercise caution in the area.

Vessel traffic has been shifted to the navigation pass at the Olmsted L/D in the vicinity of Mile 964.6. The navigation lane width is approximately 900 feet, as marked with buoys. Down-bound tow maximum dimensions are 175 feet by 1,200 feet, including the towboat, with no more than 25 regulation barges and not to exceed 5 wide. No hip barges or other deviation that could degrade normal steerage characteristics are allowed for down-bound tows. Up-bound tow maximum dimensions are 140 feet by 1,600 feet including the towboat, with no more than 28 regulation barges and not to exceed 4 wide. Up-bound tows shall have adequate power to maintain speed. All mariners shall take direction from the Olmsted L/D Control Tower.
