Update
April, 2011, Environmental Protection Agency divers surveyed the Onondaga's hull, which had been shorn of its superstructure, sunk at a pier in the Lake Washington Ship Canal near Seattle. They found no pollutants, but a recently passed state law calling for the removal of abandoned boats and barges in Washington State waters may herald her demise.
Two of Onondagas sisters ships became museum ships. The Comanche (WPG-76) served as a museum ship at Patriot's Point, South Carolina before being sunk as an artificial reef. The Mohawk (WPG-78) served as of museum ship in Key West, Florida before being sunk as an artificial reef in July of 2012.
A letter appeared in the June 2, 2011 Nome Nugget noting the dearth of WW II museum and/or memorial ships preserved in Alaska even through both it and Hawaii were the front-lines of the conflict. Four ships have been set aside in Hawaii as memorial and/or museum ships. They are the USS Arizona, the USS Utah, the USS Missouri and the USS Bowfin. The letter called for the Onondaga to be retrieved for such a purpose, using the salvage and restoration of the WW I Turkish mine-layer Nusret as a precedent. The TGC Nusret N-16 was in a similar decrepit condition as the Onondaga at this writing.
