MUSTANG BRANCH (Runnels County). Mustang Branch, previously known as Hisaw Creek, rises a half mile north of Wilmeth in northwest Runnels County (at 31°59' N, 100°07' W) and flows southeast for eleven miles before emptying into Valley Creek three miles east of Norton (at 31°52' N, 100°04' W). The creek supports scrub brush, cacti, and grasses in its upper reaches and water-tolerant hardwoods, conifers, and grasses in its lower reaches. The upstream terrain is variable, and the lower terrain is flat and marked with locally shallow depressions. The land is surfaced with muddy sand and alluvial material in the upper reaches and expansive clays downstream.
