The Caddo County town of Hydro is situated on State Highway 58, just north of Interstate 40/U.S. Highway 66, eight miles east of Weatherford, and sixty-three miles west of Oklahoma City. Extreme north Hydro lies within Blaine County. Hydro’s residents have enjoyed horseback riding and picnics to the mounds south of town. These natural features have been called “the Caddo Mounds,” “Antelope Buttes,” and “Hydro Mounds.”
