CORYELL CREEK. Coryell Creek, named for James Coryell, rises four miles northeast of Jonesboro in northern Coryell County (at 31°38' N, 97°49' W) and runs southeast for twenty-eight miles to its mouth on the Leon River, six miles southeast of Gatesville (at 31°23' N, 97°35' W). The surrounding flat to rolling terrain has local shallow depressions and is surfaced by shallow, stony clay loams that support juniper, oak, mesquite, and grasses in the upper and middle reaches of the creek. Along the creek's lower reaches grow water-tolerant hardwoods and conifers.
