General / Marine Construction (Excluding Bridges) / Dredging
The M/V ESSAYONS may be conducting dredging activities in the Columbia River, Skamokawa Bar (RM 32+24 to RM 36+05) from 03 – 10 Nov 2026. Disposal will be at RM 28 OR side. USACE requests mariners transit at their slowest safe speed to minimize wake when in the vicinity of a dredge and proceed with caution after passing arrangements have been made on VHF-FM channel 13. Vessel(s) and/or equipment may encroach into the channel. Mariners are advised that the start and ending dates for dredging activities may vary due to unforeseen on-site conditions, such as gill net fishing, weather and other factors.
