Unio (sternwheeler)

Unio was a small sternwheel-driven steamboat which operated on the Willamette and Yamhill rivers from 1861 to 1869. This vessel is primarily remembered for its having been named Unio when built in 1861, in the first year of the American Civil War, and then having the name completed, to Union, by a new, staunchly pro-Union owner, James D. Miller. Union appears to have sunk in 1869, been salvaged, and then dismantled, with the machinery going to a new steamer then being built for service on the Umpqua River.

Construction

The steamer Unio was built at Canemah, Oregon by Capt. J.T. Apperson, and launched on October 19, 1861. With the American Civil War in progress, Apperson left off the final “n” on the name.Unio was placed on the Yamhill River route from Oregon City.

Unio was small, with dimensions reported to have been 96 feet long, probably exclusive of the fantail, and 16 foot beam (width). The boat drew about 4 feet of water when loaded. The steamer was driven by two engines, each with a 9 inch bore and a 48 inch stroke.Unio was measured at 111.59 tons for the United States merchant vessel registry. The official merchant vessel registry number was 25165.
