Tourist sternwheelers of Oregon
Since the early 1980s, several non-steam-powered sternwheel riverboats have been built and operated on major waterways in the U.S. state of Oregon, primarily the Willamette and Columbia Rivers, as river cruise ships used for tourism. Although configured as sternwheelers, they are not paddle steamers, but rather are motor vessels that are only replicas of paddle steamers.
