Concho River:
The Concho River rises in three branches known as the North Concho, the Middle Concho, and the South Concho. The North Concho, the main branch and a perennial stream, originates two miles north of the Glasscock County line in southern Howard County and flows southeast for eighty-eight miles across Glasscock, Sterling, Coke, and Tom Green Counties to its confluence with the South and Middle Concho rivers, a mile north of Goodfellow Air Force Base near San Angelo, Texas. The three forks become known as the Concho River at this juncture. The O. C. Fisher Dam forming O. C. Fisher Lake was completed on the North Concho in 1951. The Middle Concho rises in southern Sterling County and flows south and then east to Twin Buttes Reservoir southwest of San Angelo, and then flows to its mouth on Lake Nasworthy on the southwest side of San Angelo. The South Concho arises half a mile east of U.S. Highway 277 in central Schleicher County and flows north for thirty-six miles through the Twin Buttes Reservoir and Lake Nasworthy to its confluence with the North Concho River. The consolidated Concho River flows east for fifty-eight miles across Tom Green and Concho Counties to its mouth on the Colorado River, one-half mile west of the Coleman County line, and one mile south of the Runnels County line in eastern Concho County, east of Paint Rock. Paint Rock is located on the Concho River proper. The Simon W. Freeze Dam forming the O.H. Ivie Reservoir is located on the Colorado River, 16 miles below the confluence of the Colorado and Concho Rivers.
