About twenty villages in the Wapato Valley were documented in the early nineteenth century, all of them likely occupied by Upper Chinook people. The largest villages were Clackstar near Scappoose, Cathlapotle on the lower Lewis River, Multnomah on the Columbia bank of Sauvie Island, the Shoto villages on Lake River north of Vancouver Lake, and Cathlacumups at the lower end of Multnomah Channel.
