Today, the American Waterways Operators celebrates its 70th anniversary as a trade association, founded on May 20, 1944, to advocate for towboat and barge operators in response to changing national transportation needs and the new regulatory climate emerging during World War II. The association has grown into a national organization representing tugboat, towboat and barge operators on the inland waterways, along the coasts, on the Great Lakes, and in ports and harbors around the country.
