FRIO WATER HOLE, TEXAS. Frio Water Hole was on the Frio River forty-nine miles northwest of Bandera in what is now Real County. The community was reportedly named for a water source used by Indians and by the Texas Rangers. The water hole, near the headwaters of the Frio River, was supposedly on the route traveled in August 1862 by a group of Union sympathizers attempting to reach Mexico; they were caught by Confederate pursuers a few days later, and the Battle of Nuecesqv ensued. A post office was established at Frio Water Hole in 1879, when Real was still part of Bandera County. In 1884 Frio Water Hole had thirty-five residents, and the principal shipments from the area were livestock and wool. The community post office was discontinued in 1888, and mail for area residents was sent to Medina.
