TRINIDAD CREEK. Trinidad Creek rises two miles south of San Diego in eastern Duval County (at 27°43' N, 98°15' W) and runs southeast for sixteen miles to its mouth on Santa Gertrudis Creek, eight miles east of Palito Blanco in central Jim Wells County (at 27°35' N, 98°05' W). The stream was named for La Trinidad, a tract granted to Santos Moreno by the Spanish government. It traverses flat terrain with local shallow depressions, surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, and grasses.
