QUINTA CREEK. Quinta Creek rises three miles northwest of Orange Grove in northeastern Jim Wells County (at 27°59' N, 97°58' W) and runs southeast for sixteen miles to its mouth on Agua Dulce Creek, six miles northwest of Banquete in northwestern Nueces County (at 27°51' N, 97°52' W). The stream traverses flat to rolling prairie, which is locally dissected in its lower reaches. The dark, commonly calcareous clays along the upper reaches of the stream and the sandy and clay loams in its lower reaches support mesquite, grasses, cacti, and scrub brush.
