TRES PALACIOS RIVER. Tres Palacios River rises on the western city limits of El Campo, twelve miles southwest of Wharton in central Wharton County (at 29°12' N, 96°18' W) and runs southeast for forty-six miles, through the Eldorado Country, Tidewater Oaks, and Tres Palacios developments, to its mouth on Tres Palacios Bay, four miles north of Palacios in southwestern Matagorda County (at 28°45' N, 96°10' W). The river is intermittent in its upper reaches. It traverses low-rolling to flat terrain with shallow depressions, surfaced by clay and sandy loams and some dark, calcareous clay. Mixed hardwoods, pines, mesquite, grasses, and cacti grow upstream; downstream, water-tolerant hardwoods and conifers predominate.
