The United States lightship Columbia (WLV-604) is a historic vessel that served as a navigational aid at the mouth of the Columbia River in Oregon. Built by Rice Brothers Shipyard in Boothbay, Maine, and launched in 1951, Columbia was the fourth and final lightship stationed at this critical maritime location. She was constructed to replace the aging vessel LV-93, which had been in service since 1939, and served alongside her sister ship, Relief (WLV-605). Columbia’s primary role was to guide vessels through the treacherous Columbia River Bar, an area notorious as the "Graveyard of the Pacific" due to frequent storms and hazardous conditions. The vessel was equipped with a permanent crew of 18 personnel, including 17 enlisted men and one warrant officer serving as captain. The crew’s duties demanded self-sufficiency, as everything needed for their long deployments—often lasting two to four weeks—had to be onboard, especially during winter months when rough weather hampered resupply efforts. Constructed as a robust and seaworthy vessel, Columbia's service was marked by periods of monotony interspersed with severe storms that tested her durability. She remained in operational service until 1979, when she was decommissioned and replaced by an automated navigational buoy, which itself has since been retired. In recognition of her historical significance, Columbia was added to the National Register of Historic Places in 1978, then delisted in 1983 after relocation, and subsequently reinstated in 1989 as a National Historic Landmark under the name Lightship WAL-604. Today, Columbia is preserved at the Columbia River Maritime Museum, positioned alongside the navigational buoy that replaced her in 1979, serving as a tangible reminder of maritime navigation history and the vital role lightships played in ensuring safe passage through dangerous waters.
