Demand for passage and freight shipments up the Columbia was very great in the early 1860s. Although only a moderate sized vessel, it was not necessary to haul large amounts of cargo for a vessel to be profitable at that that time on the river. Tenino proved to be one of the most profitable boats yet to appear on the river. As Professor Mills described it:
Teninos first captain was Leonard Wright, who had taken Colonel Wright far up the Snake River. Later captains were Charles Felton, E.W. Baughman, J.H.D. Gray, E.F. Coe and Thomas and John Stump. The company ran Tenino hard and by 1867 or 1869 the vessel had to be rebuilt.

Salvaged or reconstructed

In 1876, Tenino struck a rock while moving down river. Her hull was too old to be worth salvaging, so OSN removed the engines and installed them in a new sternwheeler, called the New Tenino. Another source states that Tenino was rebuilt a second time in 1876, and it was this reconstructed vessel that was known as the New Tenino.. A reconstruction could be almost the same as building a new vessel, so this may be a matter of characterization of the work. For example, when Rossland

was rebuilt, in the off-season of 1909-10, the upper works were jacked up, the old hull removed, and a new hull slid underneath the old deckhouse structure, which was then lowered down onto the new hull.
