Klamath Falls, city (1990 pop. 17,737), seat of Klamath co., SW Oreg., at the southern tip of Upper Klamath Lake; inc. 1905. It is the processing and distribution center of a lumber, livestock, and farm area. Timber, dairy products, and tourism are central to the city's economy. Klamath Falls was settled in 1867 as Linkville. The Klamath irrigation project (1900) on the Klamath River and the coming of the railroad (1909) stimulated its growth from a hamlet to a thriving city.
