SNAKE RIVER – LAKE SACAJAWEA
Lower Monumental Lock upstream floating guidewall repairs (Revised from LNM 15/22) Repairs to the Lower Monumental Navigation Lock floating guide wall keyway are now completed. Commercial vessels may now tie up to the floating guide wall, and may perform crew changes at that location.  River users may contact the Lower Monumental Shift Operator at (509) 2827231, or VHF-FM Channel 14 using call sign WUJ43 Lower Monumental, for more information about lockage.

SNAKE RIVER – LAKE BRYAN
Little Goose Lock temporary closure LNM: 16/22 The Little Goose navigation lock at Snake River Mile 70.3, will be closed daily 0700-1900 from 27 – 29 Apr 22 to allow a contractor to remove a hazard to navigation at the landside wall upstream of the navigation lock.  The work will involve dive operations and require mooring of a dive support vessel in the navigation channel. As contract work allows, navigation traffic will be passed through the work zone during the above working hours.  For additional information on this work contact the NWW Operations Division at (509) 527-7364.

WASHINGTON – PUGET SOUND – SEATTLE TO BREMERTON – DUWAMISH WATERWAY
Bridge emergency deviation (Revised from LNM 11/22) The Coast Guard has approved an emergency temporary deviation from the operating regulations of the 1st Ave South Highway Bridge (LLNR 16887), AKA SR-99 Bridge, across the Duwamish Waterway, mile 2.5, Seattle, WA.  The subject bridge sustained damage from a roadway accident, and the draw span is limited to opening when sustained winds are less than 10 knots.  The bridge operator may exercise good judgement to delay or not open the draw for a reasonable time only when sustained winds exceed 10 knots. The bridge operator may delay the opening of the draw for a reasonable time while waiting for sustained winds to be less than 10 knots, but shall inform mariners for the reason of delayed openings. Mariners shall contact the bridge operator prior to entering the Duwamish Waterway to request an opening, if the bridge cannot open due to wind velocity, the bridge operator shall record the vessel(s) name and contact them every thirty minutes with a draw status. The reasonable delay to open due to damages applies to all vessels requesting an opening including vessels of 5000 gross tons and over, a vessel towing a vessel of 5000 gross tons and over, and a vessel proceeding to pick up for towing a vessel of 5000 gross tons and over. During this closure, the draw of the subject bridge may also delay opening the draw to marine vessels engaged in emergency operations.  Repairs to the bridge are taking longer than anticipated as some necessary parts are being fabricated.  Once delivered WSDOT will complete the repairs.

WASHINGTON – PUGET SOUND – HOOD CANAL – Multi-agency exercise operations
Naval Base Kitsap will be conducting Force Protection exercises on 21 Apr from 0900 – 1700, on the waterfront adjacent to Naval Base KitsapBangor in the Hood Canal, and will occur in an area by the following positions:  47-46-05 N / 122-42-56 W  47-46-32 N / 122-44-43 W  47-44-11 N / 122-44-26 W  47-44-12 N / 122-46-22 W Mariners are requested to remain at least 500 yards away from the area outlined, as well as military, federal and state agency vessels. Participating vessels will be operating at high speeds and performing maneuvers during the exercise.  Live fire and explosive devices may be used by participating vessels.  Security vessels can be reached on VHF-FM channel 21A.

NORTHERN CALIFORNIA-SAN JOAQUIN RIVER-MARINE CONSTRUCTION
The Department of Water Resources have placed an emergency barrier in the West False River until December, 2022. The barrier is located at 38-03-25N 121-40-08W  and is approximately 0.4 mile east of the confluence with the San Joaquin River, between Jersey and Bradford Islands in Contra Costa County, and is about 4.8 miles northeast of Oakley. Constructing the emergency temporary rock barrier provides a method of controlling saltwater intrusion into the Delta and the barrier was installed in the identical location in 2015. Mariners are requested to transit the area with caution. For more details or comments contact Jason Bacher at 916-376-9859 or Keith Boulton

 

SECTION V - ADVANCE NOTICES

This section contains advance notice of approved projects, changes to aids to navigation, or upcoming temporary changes such as dredging, etc.  Mariners are advised to use caution while transiting these areas.

WASHINGTON – WILLAPA BAY - Disestablishment of Willapa Bay Lighted Buoy “C” and Buoy “D” (Revised from LNM 09/22)
The U.S. Coast Guard will be permanently disestablishing Willapa Bay Entrance Lighted Buoy “C” (LLNR 15186) and Willapa Bay Entrance Buoy “D” (LLNR 15167) as the constantly shifting bar at the entrance to Willapa Bay prevents these buoys from marking the navigable channel, and surf conditions make the placement, retrieval and servicing of these buoys hazardous. There are currently no plans by the US Army Corps of Engineers to dredge or maintain the entrance channel into Willapa Bay. Virtual AIS (V-AIS) signals are expected to be established in place of these buoys. The projected approximate locations are: Willapa Bay V-AIS “A”, a special purpose AIS marking good water at 46-44-21N  124-06-16W

Willapa bay V-AIS “B”, a special purpose AIS marking good water at 46-43-45N  124-04-12W

Mariners are encouraged to share comments on the performance and operation of aids to navigation. All comments should be sent to the email address of D13-SMB-D13-LNM@uscg.mil. Any discrepancy for Aids to Navigation should continue to be reported to US Coast Guard Sector Columbia River.

WASHINGTON – PUGET SOUND –STRAIT OF JUAN DE FUCA TO STRAIT OF GEORGIA - Removal of ball topmarks from Isolated Danger Buoys
The U.S. Coast Guard will be removing the two black ball topmarks from the Isolated Danger Buoys listed below. This action is due to recurring damage of the topmarks from weather events, and the debris has interfered with the visibility of the light signal.
