NORTH CONCHO RIVER
NORTH CONCHO RIVER. The North Concho River rises in southern Howard County (at 32°07' N, 101°27' W) near Farm Road 461 and two miles north of the Glasscock county line, and runs southeast for ninety-eight miles, passing through Glasscock, Sterling, Coke, and Tom Green counties before reaching its mouth (at 31°27' N, 100°25' W), where it intersects the South Concho and Middle Concho rivers to form the Concho River in San Angelo. The North Concho River lies in a natural geologic floodplain composed of sand, gravel, and mud substrate with some bedrock areas. Water-tolerant hardwoods, conifers, and grasses grow in the clay and sandy loams along the river. Northwest of San Angelo the North Concho River is dammed to form O. C. Fisher Lake.
