MIDDLE CONCHO RIVER
MIDDLE CONCHO RIVER. The Middle Concho River rises in Centralia Draw in eastern Upton County (at 31°38' N, 101°13' W) and flows east ninety miles, across Reagan and Irion counties, to its mouth on the Twin Buttes Reservoir, in west central Tom Green County (at 31°23' N, 100°31' W). Before Twin Buttes Reservoir was constructed in 1963, the stream joined the North and South Concho rivers and was dammed in 1930 to form Lake Nasworthy. Tributaries of the river include North and South Liveoak creeks, Bradford Draw, and Dry and Rocky creeks. Juan Dominguez de Mendoza, accompanied by Jumano Indians, followed the river for over twenty leagues in 1683, and the river was used by Comanches and others as a route westward. Major floods occurred on the river in 1882 and 1936. The surrounding terrain is flat with local shallow depressions, surfaced by clay and sandy loam soils that support water-tolerant hardwoods, conifers, and grasses.
