Ballasting operations were completed Thursday night on the SS Davy Crockett, the derelict ship moored on the north shore of the Columbia River near Camas.
According to the U.S. Coast Guard, during the operation crews lowered the stern 17-feet to allow four remotely operated pumps to flood cargo hold compartments with approximately 600,000 gallons of water. The goal is to determine the location of pollutants that remain on the vessel.
