Okanogan was officially incorporated on October 29, 1907.
A pair of 115 year old long murals were discovered during renovation of a 1907 commercial building in January 2022. The murals were initially tentatively attributed to Western photographer Frank S. Matsura as the building had been used as a theater several times and Matsura had played in the Okanogan County Band on stage there. The mural is painted on canvases split between the north and south walls, and a 1915 newspaper clipping found by the Okanogan County Historical Society provided coverage of plans for the murals. Then the Hub Theater, the building was planned to incorporate panoramic scenery murals in tans painted by a local artist. The owners planned to take the murals down for restoration before rehanging them as the centerpiece of a historical exhibit.
