WALNUT CREEK (Johnson County). Walnut Creek rises six miles northeast of Keene in northeastern Johnson County (at 32°27' N, 97°16' W). Intermittent in its upper reaches, the stream enters Tarrant County just southwest of Mansfield. In its extreme lower reaches it serves as the official boundary between Grand Prairie and Dallas. The creek runs northeast twenty-seven miles to its mouth on Mountain Creek, in western Dallas County four miles west of Duncanville (at 32°38' N, 97°00' W). It crosses low rolling to flat terrain surfaced by sandy and clay loams that support water-tolerant hardwood trees, conifers, scrub brush, cacti, and grasses. Urban development is important in the vicinity of the lower reaches.
