Turner County boasts having the oldest county fair in the Dakotas. Turner County held the first county fair in Dakota Territory, October 13-16, 1880. There are few records from that first fair but The New Era records show that the Turner County Agriculture Society was organized in March, 1880. The society was formed with the express purpose of showing the success and agricultural achievements of the newly settled country. The first fair was held on the Devereaux property which was north on the corner north of the road which leads to Rosehill Cemetery at Parker. There a race track and ball diamond were constructed as well as a bridge which connected the end of Second Street across the river to the fair grounds. The fair was held at various locations over the years but the fair has been at its current location along Highway 44 on the east side of Parker for well over half a century. 
The county is divided into eighteen townships:
