FOYLE CREEK. Foyle Creek rises five miles north of Albany in northeastern Shackelford County (at 32°51' N, 99°24' W) and runs northeast for twenty-two miles to its mouth on the Clear Fork of the Brazos River, six miles southeast of Fort Griffin State Historic Site (at 32°53' N, 99°08' W). The creek is dammed in its upper reaches. It initially traverses an area of steep slopes and benches surfaced by shallow clay loams that support juniper, live oak, mesquite, and grasses. In the creek's lower reaches the terrain becomes flat with local shallow depressions and is surfaced by clay and sandy loam soils that support water-tolerant hardwoods, conifers, and grasses.
