Established in 1891 as the Castro County seat. It is named for Rev. W.C. Dimmitt. The hard feelings after Dimmitt was selected over Castro City as county seat led to a gunfight between Ira Aten, a retired Texas Ranger, and Andrew McClelland. A historical marker at the courthouse square commemorates the event. The county excels in agriculture, producing corn, wheat, sunflowers, sugar beets, potatoes, carrots, onions and cucumbers.
