Blaine county is located in west central Oklahoma and calls Watonga its county seat. Originally tagged "C" county prior to the Land Run in 1892, the name was changed in honor of the late Sen. James G. Blaine. Watonga is named in honor of Wa-ton-gha, an Arapaho chief and means "black coyote."
The North Canadian River enters from the northwest immediately forming Canton Lake before continuing its southeasterly flow exiting the county east of Greenfield. Roman Nose State Park, located near the center of the county, provides a scenic getaway for area residents and visitors alike.
The county population on July 1, 1999, was 10,284, a decrease of 1,186 over the 1990 census.
