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 Outdated URLs will automatically redirect to the home page of the site, and from there you will be able to easily navigate to your preferred page.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.

UPPER MISSISSIPPI RIVER - CHANNEL CONDITION/COTP SAFETY ADVISORY – UPDATE

The following zones are in the low water watch phase IAW the Western Rivers WAP Annex:

  • Zone 28 (Mile 185.4 – Mile 160.1) and
  •  Zone 29 (Mile 160.0 – Mile 101.9).

Mariners should exercise caution, beware of shifting channels, transit at their slowest safe speed to minimize their wake near fleeting areas and place heavy barges in the middle of their tows. Deep draft tows are advised to depart these areas. Mariners are urged to exercise caution in these areas and contact U.S. Coast Guard Sector Upper Mississippi River via VHF-FM Channel 16 or at (314) 269-2332 or e-mail at sumrwaterways@uscg.mil, to report shoaling, hazardous conditions or missing aids to navigation.

 

SECTION VI - PROPOSED CHANGES

Periodically, the Coast Guard evaluates its system of aids to navigation to determine whether the conditions for which the aids to navigation were established have changed. When changes occur, the feasibility of improving, relocating, replacing, or discontinuing aids are considered. This section contains notice(s) of non-approved, proposed projects open for comment. SPECIAL NOTE: Mariners are requested to respond in writing to the District office unless otherwise noted (see banner page for address).
