Sidney is a city in and the county seat of Richland County, Montana, United States,[2] less than 10miles west of the North Dakota border. The population was 6,346 at the 2020 census.[3] The city lies along the Yellowstone River and is in proximity to the badlands of the Dakotas. Sidney is approximately midway between Glendive, Montana and Williston, North Dakota.
Settlers began arriving in the area in the 1870s, and a post office was established in 1888.[4] Six-year-old Sidney Walters and his parents were staying with Hiram Otis, the local justice of the peace, and Otis decided that Sidney was a good name for the town. The following year, Montana became a state and Sidney was incorporated in 1911.[5]
Sidney was originally part of Dawson County, but became the county seat of Richland County at its inception in 1914.[6]
Agriculture became an important part of the region after the Lower Yellowstone Irrigation Project[7] was completed in 1909. A dam was built on the river south of Glendive, which diverted water from the river into a 115.2km (71.6miles) main canal, which runs north–south, parallel to the Yellowstone, irrigating land from Glendive north up to Fairview, where it dumps into the Missouri River. This project irrigates 51429acres and serves water to 450 farms, according to the manager of the Lower Yellowstone Irrigation Districts.[8]
During the Great Depression, Montana artist J. K. Ralston painted a Federal Arts Project mural at the Richland County Courthouse in Sidney.[9]
The town received a boost in 1924 when the Holly Sugar Company opened up a sugar refinery in Sidney to process locally grown sugar beets.
The area experienced an oil boom and bust in the late 1970s and early 1980s, bringing an influx of people to the town for a short period of time. Around the start of the 21st century, the town experienced another surge in oil exploration activity.[10]
Sidney is located in the northeastern part of the state at (47.712519, -104.161486),[11] at an altitude of 1,949 feet (594 m).
According to the United States Census Bureau, the city has a total area of 2.68sqmi, of which 2.66sqmi is land and 0.02sqmi is water.[12]
Sidney is 270miles northeast of Billings, and 190miles south of Regina, Saskatchewan.
Sidney experiences a semi-arid climate (Köppen BSk) with long, cold, dry winters and hot, more humid summers.
Sidney relies heavily on farming, ranching, and oil production for economic stability. The surrounding countryside is populated with many farms and cattle ranches, plus oil exploration activity. The area's main cash crop are sugar beets, and Sidney is home to a sugar beet factory, built in 1925. The factory is the largest employer in the city, next to the Sidney Health Center[13] and Sidney Public Schools.[14]
The sugar beet factory, owned by the American Crystal Sugar Company, was scheduled to close in April 2023. [15]
The town's museum, the MonDak Heritage Center,[16] was founded in 1967. The museum houses artifacts and archives that detail the history of life in eastern Montana and western North Dakota since the first pioneers arrived in the late 19th century.
Sidney has a public library, the Sidney-Richland County Library.[17]
The town of Sidney has a Mayor and City Council. The City Council has 3 wards, each with 2 councilors.[18] In 2023 the Mayor was Rick Norby.[19]
Sidney has four public schools; one K, 1st, and 2nd grade (Westside Elementary) elementary school, a 3rd, 4th and 5th grade (Central Elementary) Elementary school, a 6-8 Junior High School, and a 9-12 senior high school.[20] Sidney High School's team name is the Eagles.[21]
There are no institutions of higher education located within the city, but Williston State College in North Dakota is within commuting distance. MSU-Billings[22] offers courses through telecommunication, and Sidney High School has a variety of adult education classes each year.
The city has two community newspapers, The Sidney Herald[23] and The Roundup.[24]
The eastern end of Montana Highway 16 joins Highway 200 in Sidney.
