Rieth is an unincorporated community in Umatilla County, Oregon, United States. It is south of Interstate 84/U.S. Route 30/U.S. Route 395 about 5miles west of Pendleton near the Umatilla River.[1]
Rieth was an important division point of the Oregon–Washington Railroad and Navigation Company, which named the station at the new shops and terminals it constructed there after a local pioneer family, the Rieths.[2] [3] The railway's Pilot Rock Line, constructed in 1907, joined the mainline in Rieth.[4] [5] This line was once the Umatilla Central Railroad.[4] In 1917, the Post Office Department established an office named "Reith".[3] The name was soon corrected by the United States Board on Geographic Names.[3] The post office closed in 1971.[3] The main railroad yards, now owned by Union Pacific, were later moved to Hinkle.[3]
In 1922, Rieth had a population of 200, a school, a store, and other businesses.[2] In 1940 Rieth had a population of 45.[6]
