SAN ANDREAS CREEK. San Andreas (San Andrés) Creek rises two miles southwest of San Diego in eastern Duval County (at 27°44' N, 98°15' W) and runs east for twenty-one miles, across Jim Wells County, to its mouth on Patricio Lake, on Santa Gertrudis Creek ten miles east of Palito Blanco in northwestern Kleberg County (at 27°35' N, 98°02' W). The stream is apparently named for the Spanish San Andrés land grant made to Andrés García. It traverses flat to gently rolling terrain with local depressions and escarpments, surfaced by shallow to deep clay and sandy loams that support water-tolerant hardwoods, conifers, scrub brush, and grasses.
