WASHINGTON – PUGET SOUND – EVERETT HARBOR – SNOHOMISH RIVER – Shoaling  (Originally published in USCGD13-LNM 18/19)

Significant shoaling has been reported in several locations in the Snohomish River both in and outside the federally maintained navigation channel causing actual depths to be less than advertised. Recently, a tug grounded inside the channel in approximate position, 48-00-28.86N, 122-13-29.52W.  Mariners are advised to use extreme caution when transiting the river.  The next planned dredging of the channel is in October 2019. The latest survey data from USACE is from Jan 2019 and can be found here Snohomish Hydro Survey January 2019

Marine Events in Oregon, Washington Idaho and Montana.

Holding a Marine Event?  As stated in 33 CFR (Code of Federal Regulations) Part 100 (33 CFR 100), an individual or organization planning to hold a regatta or marine parade which, by its nature, circumstances, or location, introduces any extra or unusual hazard to the safety of life on the navigable waters of the United States, must have the event approved by the cognizant Coast Guard authority. Sponsors of these events must submit an Application for Approval of Marine Events in accordance with 33 CFR 100. 

Click here to complete and submit a "Marine Event Request Form!"

For a list of waterways within the 13th Coast Guard District that are considered navigable for the purposes of exercising Coast Guard authority and jurisdiction contact the Waterways Management Branch.

Timeline for Submission: Applications need to be submitted no later than 135 days prior to the start of the proposed event. If your event meets the following provisions you may submit your permit no later than 60 days prior to the start of the event:

 1.  The sponsor submitted an application for the same event in the year immediately preceding.
 2.  The relevant information contained in the previous application is essentially the same.
 3.  The Coast Guard received no objection to the previous application.
 4   The Coast Guard did not promulgate special local regulations for the previous event.
 5   The Coast Guard approved the previous event.

Late Applications: For applications received late, if a review of the application shows that a permit is required, and if the permit application cannot be processed in time for the event, the sponsor will be notified that the permit cannot be issued. We review each permit application; therefore, it is critical to include the following information for each event: sponsor name, date and time of event, type of event, location, sponsor's point of contact, on the water and/or on site, and the number of participating and spectator craft. Once your marine event has been approved you will receive a Marine Event Permit Approval Letter from either Sector Puget Sound or Sector Columbia River, which states your permit number and the responsibilities and obligations you have as an event sponsor. Should there be any doubt or questions regarding those responsibilities please notify us so we can clarify them prior to your event taking place. 



Broadcast Notice to Mariners (BNM)

Broadcast Notices to Mariners are made by the Coast Guard through Coast Guard and Navy radio stations.  These broadcast notices, which are broadcast on VHF-FM, NAVTEX, and other maritime frequencies, are navigational warnings that contain information of importance to the safety of navigation. Included are reports of deficiencies and changes to aids to navigation, the positions of ice and derelicts, and other important hydrographic information.

Local Notice to Mariners (LNM)

Local Notices to Mariners (U.S. regional coverage) are another means by which the Coast Guard disseminates navigation information for the United States, its territories, and possessions.  A Local Notice to Mariners is issued by each Coast Guard district and is used to report changes and discrepancies to aids to navigation maintained by and under the authority of the Coast Guard.  Local Notices to Mariners contain other marine information such as channel depths, naval operations, regattas, etc., which may affect vessels and waterways within the jurisdiction of each Coast Guard district.  Reports of channel conditions, obstructions, menaces to navigation, danger areas, new chart editions, etc., are also included in the Local Notice to Mariners.  These notices are essential to all navigators for the purposes of keeping their charts, Lights Lists, Coast Pilots and other nautical publications up-to-date.  These notices are published as often as required, but usually weekly.  Click here to obtain a copy of the District 13 Local Notice to Mariners (LNM) via the U.S. Coast Guard Navigation Center website. Vessels operating in ports and waterways in several districts will have to obtain the Local Notice to Mariners from each district in order to be fully informed.

Special Notice to Mariners (SNM)

The Special Notice to Mariners is an annual publication containing important information for the mariners transiting the waterways of the Thirteenth Coast Guard District. Thirteenth District waterways include the seacoast from the California/Oregon border to the United States/Canadian border, and all federally navigable waterways in Idaho, Montana, Oregon and Washington.  Click here for a copy of the District 13 Special Notice to Mariners (SNM).
