Mule Barn was a small former town in Pawnee County, Oklahoma, United States, located on the west side of Keystone Lake west-northwest of Tulsa. Its population was recorded as zero in both the 1990 and 2000 enumerations.
Construction of Keystone Dam in the 1960s encouraged scattered settlement on the Keystone Lake peninsula. In 1976âÂÂ1977, residents in southeastern Pawnee County pursued incorporation of numerous microâÂÂcommunities to prevent annexation by nearby Westport. Mule Barn ultimately held corporate status from 1985 until its dissolution in 2008, one of only two such KeystoneâÂÂarea microâÂÂtowns (along with Oak Grove) to remain incorporated for more than a brief period.
Under Oklahoma law, a town may be involuntarily dissolved when it ceases to functionâÂÂsuch as when general municipal elections are not called for two successive cycles or when officials fail to qualify for two successive elections. The U.S. Census BureauâÂÂs geographic change notes document selected legal boundary changes, including deletions of incorporated places during the 2000âÂÂ2010 period; Mule Barn was deleted (dissolved) in 2008.
