Jefferson County County
Jefferson County was established in 1914 from a portion of Crook County. It was named for Mount Jefferson on its western boundary. The county owes much of its agricultural prosperity to the railroad, which arrived in 1911, and to the development of irrigation projects in the late 1930s. The railroad, which links Madras with the Columbia River, was completed after constant feuds and battles between two lines working on opposite sides of the Deschutes River.
