HOG CREEK (Hamilton County). Hog Creek rises six miles east of Jonesboro in extreme southeastern Hamilton County (at 31°38' N, 97°49' W) and runs forty-three miles southeast, passing through Coryell and Bosque counties, to its mouth on Lake Waco, in central McLennan County (at 31°31' N, 97°15' W). It traverses variable terrain, surfaced by shallow, stony clay and sandy loams that support juniper, oak, chaparral, mesquite, and cacti, as well as water-tolerant hardwoods, conifers, and grasses.
