NAIL CREEK. Nail Creek rises three miles northwest of Tenaha in northern Shelby County (at 31°58' N, 94°18' W) and runs northeast for eight miles through southern Panola County to its mouth on Murvaul Creek, two miles west of Murvaul (at 32°04' N, 94°16' W). It traverses generally flat terrain, surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, and grasses.
