A petroleum barge operated by Vancouver-based Tidewater Barge struck a part of the locks at The Dalles Dam, but no pollution resulted. After a survey by the U.S. Coast Guard and marine safety inspectors, the double-bottom barge Tri-City Voyager and tug Defiance were allowed to continue upstream.
Coast Guard investigators concluded that the barge struck the walls of the lock approach to The Dalles and not a submerged object, as was initially reported.
The Tri-City Voyager was loaded with 1.77 million gallons of diesel fuel, according to a news release from the U.S. Coast Guard.
