CENTRALIA DRAW. Centralia Draw rises thirteen miles northeast of Rankin in eastern Upton County (at 31°19' N, 101°52' W) and runs east for forty-five miles across Upton, Reagan, and Irion counties to its mouth on the Middle Concho River, just east of the Reagan-Irion county line in western Irion County (at 31°26' N, 101°15' W). The draw crosses Farm roads 1555, 1800, and 33 and runs through the Stiles community in north central Reagan County. Centralia Draw is on a natural floodplain and has a bed of sand, gravel, and mud substrate. Water-tolerant hardwoods, conifers, and grasses grow along its banks.
