Hydro is a town in Blaine and Caddo counties in the U.S. state of Oklahoma. The population was 1,060 at the 2000 census. Hydro was home to Lucille Hammons, a Route 66 icon dubbed "The Mother of the Mother Road. " Her motel and gas station still stand on Old Route 66 just west of Hydro. A modern replica of the station, with a large restaurant attached, is in nearby Weatherford. In downtown Hydro, an old-fashioned drug store still serves sodas and lunch. Also downtown is the "World Famous Hydro Bar. " The bar has been in business since the early years of Hydro and still has pictures of the old-fasioned wood swinging doors that used to be the front doors to the bar. Minnie Lou Bradley, matriarch of the Bradley 3 Ranch in the Texas Panhandle, grew up on a wheat farm near Hydro.
