Canadian County is a county located in the U.S. state of Oklahoma. As of the 2020 census, the population was 154,405, making it the fourth most populous county in Oklahoma. Its county seat is El Reno.

The county is named for the Canadian River, which forms part of its southern border. The river may have been named for early European explorers who were fur traders and trappers from New France, or pre-1763 colonial Canada.

History

In 1859, the United States expelled the Caddo Nation of Louisiana from its Brazos reservation in Texas and relocated it to what would eventually become Canadian County, Oklahoma. Showetat, the last hereditary chief of the Caddo, set up his camp here and is considered Canadian County's first permanent resident. (Union City developed near his camp site.)

The federal government relocated the Wichita tribe to this same part of Indian Territory in 1861. By the Treaty of Medicine Lodge, the United States assigned the land west of the Caddo and Wichita to the Cheyenne and Arapaho tribes. They were relocated from Colorado in 1869. The Cheyenne-Arapaho Agency (later renamed the Darlington Agency) was established in 1870.

Canadian County was formed in 1889 as County Four of Oklahoma Territory as part of the Oklahoma Organic Act, which created Oklahoma Territory from part of Indian Territory. It was named after the Canadian River, which runs through the county.

This county was settled by European-Americans after the April 22, 1889, land run, which gave away expropriated Native American land. It was expanded by a second land run in 1892. In 1902, after distribution of communal lands among households of the Cheyenne and Arapaho, their 'surplus' lands were opened to European-American settlement. El Reno was chosen as the county seat over competitors Reno City, Frisco, and Canadian City.

The county was the location of the last great battle of the Cheyenne and Arapaho against United States Army forces.

Geography

According to the U.S. Census Bureau, the county has a total area of , of which is land and (1.0%) is water. The county lies mostly within the Red Bed Plains, a subregion of the Osage Plains physiographic region. Its northwestern corner is in the Gypsum Hills. The county is drained by the North Canadian River and the Canadian River, which both flow through the county from northwest to southeast.

According to a study published by the Oklahoma Geological Survey, the North Canadian River drains about 40 percent of the county, the Canadian River drains about 32 percent, and the Cimarron River drains about 27 percent (mostly in the northeastern part of the county). About 1 percent of the county is drained by Sugar Creek, which empties into the Washita River, itself a tributary of the Red River.

The North Canadian River enters Canadian County near the northwest corner, flows generally southeast towards the middle of the county, then turns southward to leave the county about north of the southeastern corner. The river length is about . The elevation drops from at the entry to about at the exit. Its named tributaries are Sixmile Creek, Fourmile Creek, Purcell Creek, Shell Creek, and Mustang Creek.

The Canadian River enters the western border of the county about north of the southwest corner at an elevation of and flows southeast about , where it becomes the southern border of the county. Its course within the county is long, and the elevation where it leaves the county is . Named tributaries include Dry Creek and Boggy Creek.

The Cimarron River does not flow through the county, but drains part of the northeastern area via its tributaries: Kingfisher, Dead Indian, Uncle John, Cottonwood, Soldier, and Deer creeks. The Washita River flows more than south of the county, but drains about in the southwest corner of Canadian County.
