WK 10-14: WASHINGTON – PUGET SOUND – SHIP CANAL – Changes to Aids to Navigation at Shilshole Bay Entrance
The U.S. Coast Guard is proposing to make a number of changes to the Aids to Navigation for Shilshole Bay Entrance. These changes are proposed due to consistent discrepancy status of the Shilshole Bay Entrance Range. To correct these discrepancies would entail the removal and brushing of a vast number of tress at the Commodore Park, and on private property. This proposal is designed to eliminate the need to remove the foliage and still provide navigational safety at the entrance. The following changes would be made:
- Shilshole Bay Approach Lighted Buoy “S” (LLNR 16785 & 18110): Disestablish as no longer necessary for safe navigation.
- Shilshole Bay Entrance Buoy 1 (LLNR 18125): Change to Shilshole Bay Entrance Lighted Buoy 1, with a green flashing light, every 2.5s (Fl G 2.5s) and a nominal range of 4 NM.
- Shilshole Bay Entrance Buoy 2 (LLNR 18130): Change to Shilshole Bay Entrance Lighted Buoy 2, with a red flashing light, every 2.5s (Fl R 2.5s) and a nominal range of 4 NM.
- Shilshole Bay Breakwater Light 3 (LLNR 16790 & 18140): Change the light characteristic to a green flashing light, every 4s (Fl G 4s) to prevent misidentifying the light with Shilshole Bay Entrance Lighted Buoy 1.
- Shilshole Bay Entrance Range Front Light (LLNR 18115): Change to Shilshole Bay Entrance Direction Light, displaying an green Occulting light every 4s (Oc G 4s), increase the intensity and narrow the display of the light to be shown 1.5° either side of the channel
WK 09-14: WASHINGTON – SWINOMISH CHANNEL – Reported shoaling in the South Entrance
Shoaling has been reported in the Swinomish Channel, on the north side of the channel between Swinomish Channel South Entrance Daybeacon 13 (LLNR 18826) and Swinomish Channel South Entrance Light 11 (LLNR 18815) in the vicinity of Goat Island. The USACE survey from Nov 2012 shows the channel varying from 8 feet to 14 feet in the vicinity. The southern Swinomish Channel has a history of shoaling, therefore, mariners are advised to transit this waterway at the highest tide possible and exercise good seamanship and voyage planning.

WASHINGTON – LAKE WASHINGTON – SR520 BRIDGE: Special Bridge Notice (Revised from LNM WK: 30/13)
The USCG has revised the draw span operating schedule for the SR 520 Evergreen Point Floating Bridge. Construction activities will continue for the duration of the bridge replacement project until approximately 30 Aug 15. Vessels which are impacted by the closure of the east channel that are not able to navigate through the west channel of the existing bridge may request an opening of the center draw span for passage. Boaters may request a draw span opening by calling WSDOT at (206) 440-4490. Eight temporary white mooring buoys (six on the north side and two on the south side) marked with FL W 4s (flashing white four seconds) lights have been deployed near the bridge for the temporary mooring of construction barges. Refer to LNM 05/13 chart 18447 for temporary chart corrections. For up to date schedule changes and special event schedules for the SR 520 Bridge, please visit WSDOT’s web site at: http://www.wsdot.wa.gov/Projects/SR520Bridge/WeekendClosures.htm. The Evergreen Point Floating Bridge (SR 520) between Seattle and Bellevue shall operate as follows (revised schedule):
1. Currently, the east navigation channel under SR 520 is blocked by construction activities. However, on the special dates listed below, the navigation channel will be temporarily open to boaters. Unfortunately, due to construction equipment that cannot be moved, the vessel clearance within the navigation channel has decreased from 64 feet to 59 feet. All mariners with vessels taller than 59 feet must continue to use the floating bridge center draw span.
Both the east and west navigation channels beneath SR 520 will be open on the following dates in 2014:
1. The draw need not open from 0630 to 0959 and from 1500 to 1900 Monday through Friday, except Federal Holidays other than Columbus Day.
2. The draw need open only on the hour and half hour from 1000 to 1430 every day of the week, if at least 2 hour advance notice is given.
3. The draw will open on request at all other times if at least 2 hours advance notice is given.
4. Telephone requests for bridge opening may be directed as collect calls to the Highway Radio, or made by direct telephone communication through the Seattle Marine Operator, Station KOH, or through other marine wire or radiotelephone service.
1. Eight temporary pilings (two groups of four pilings) marked with FL Y 4s (flashing yellow four seconds) lights have been placed in the southeast part of Union Bay near the west end of the bridge for the temporary mooring of pontoons. Refer to LNM 05/13 chart 18447 for temporary chart corrections.
2. The west channel has a clearance of 45 feet.
3. Enclosure 3 shows 12 temporary barge mooring pilings have been placed on the north side of the bridge just west of the west navigation channel. All 12 pilings are marked with QY (quick flashing yellow) lights, which may be obscured at times when barges and other equipment are moored at the site.
WK 47-13: WASHINGTON – STRAIT OF JUAN DE FUCA – SWINOMISH CHANNEL – Reported shoaling
A report of shoaling in the Swinomish Channel has been made after transiting the Swinomish Channel South Entrance. A mariner stated the total water depth was 7 feet while transiting on a +2 feet tide IVO Swinomish Channel South Entrance Buoy 1 (LLNR 18785) and Goat Island. The latest USACE survey shows the channel is less than 12 feet in this location. The southern Swinomish Channel has a history of shoaling every year, therefore, mariners are advised to transit this waterway at the highest tide possible and exercise good seamanship and voyage planning.
