Owasso began as a settlement in 1881, located in the Cooweescoowee District of the Cherokee Nation in Indian Territory, near what is now 66th Street North and North 129th East Avenue. It was called Elm Creek and was named for Elm Creek, a tributary of Bird Creek. The first settler was H.T. (Tole) Richardson. In June 1893, plans began for a rail line to be extended south from Bartlesville to the cattle ranches in the vicinity of Bird Creek. At that time, already several residences, a blacksmith shop, and a general store were in the Elm Creek settlement. Preston Ballard, owner of the general store, established a post office in the general store on February 10, 1898, and was appointed the first postmaster.
