PETRONILA CREEK. Petronila Creek is formed by the confluence of Agua Dulce and Banquete creeks, a mile southeast of Banquete in western Nueces County (at 27°48' N, 97°47' W). It runs southeast for forty-four miles to its mouth on Cayo del Mazón, sixteen miles northeast of Riviera Beach in eastern Kleberg County (at 27°28' N, 97°32' W). The stream is named after the Spanish government's Santa Petronila land grant to José Antonio Cabazos in what is now Nueces County. The surrounding terrain varies from flat with local shallow depressions to some locally dissected rolling areas. It is surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, grasses, some scrub brush, and cacti. The last six miles of the streambed lie athwart tidal flats surfaced by blue-green algal mats and crustaceans.
