Tantabogue Creek rises two miles southwest of Crockett in south central Houston County (at 3117' N, 9530' W).
The creek formerly flowed southeast for twenty-six miles to its mouth on White Rock Creek in western Trinity County (at 3101' N, 9521' W). Since the construction of Lake Livingston in the late 1960s the creek has been inundated in its lower reaches. It crosses flat terrain surfaced by clay and sandy loam that supports water-tolerant hardwoods, conifers, and grasses.
