                                County History Jefferson 
                                County was created on December 12, 1914, out of 
                                territory that was once part of Crook County. 
                                The county was named after Mount Jefferson, the 
                                second highest peak in Oregon with an elevation 
                                of 10,497 feet, which marks the county's western 
                                skyline. The county is bounded on the north by 
                                Wasco County, on the east by Wheeler and Crook 
                                Counties, on the south by Deschutes County, and 
                                on the west by Linn and Marion Counties. The county 
                                encompasses 1791 square miles.  Madras, 
                                named after the city in India, was incorporated 
                                in 1911 and serves as the county seat. A new county 
                                courthouse was built in 1961. County government 
                                is administered by a three-member board of commissioners. 
                                 The 
                                county's population at its first federal census 
                                in 1920 was 3,211. The 2000 population of 19,009 
                                represented a 39% increase from 1990.  Principle 
                                industries are agriculture, forest products, and 
                                recreation. The fertile North Unit Irrigation 
                                District in the central part of the county produces 
                                seed, potatoes, hay, and mint. The eastern part 
                                of the county has dry wheat farming and grazing 
                                land for cattle, and the western part is timber 
                                country. The Warm Springs Forest Product Industry 
                                owned by the Confederated Tribes of the Warm Springs 
                                Reservation is the single largest industry. The 
                                reservation is located on portions of land in 
                                four counties including 236,082 acres in the northwestern 
                                corner of Jefferson County.  The 
                                county owes much of its agricultural prosperity 
                                to the arrival of the railroad in 1911 and to 
                                the development of irrigation projects in the 
                                late 1930s. The railroad, linking Madras with 
                                the Columbia River, was completed after constant 
                                feuds and battles between two lines working opposite 
                                sides of the Deschutes River. Jefferson County
