POSTOAK CREEK (GRAYSON COUNTY)
POSTOAK CREEK (Grayson County). Postoak Creek rises in north central Grayson County (at 33°41' N, 96°39' W) 2½ miles northwest of Sherman and runs southeast for twelve miles to its mouth (at 33°35' N, 96°33' W) on Choctaw Creek, two miles southeast of Sherman. It traverses flat to rolling prairie, surfaced by soils that range from dark, commonly calcareous clays to clayey and sandy loams. The local vegetation includes mesquites, water-tolerant hardwoods, conifers, and various grasses. The region, which historically has served as crop and range land, in the late twentieth century supported the urban population of Sherman.
