OSO CREEK (Nueces County). Oso Creek rises near the western edge of Corpus Christi three miles northeast of Robstown in northern Nueces County (at 27°49' N, 97°37' W) and runs southeast for twenty-eight miles to its mouth on Cayo del Oso, three miles southwest of Corpus Christi Naval Air Station (at 27°39' N, 97°21' W). It traverses flat to rolling terrain surfaced by dark, calcareous clays that support mesquite, grasses, and cacti. The stream has been identified as the one named La Purísma Concepción by Capt. Joaquín Orobio y Basterra during his exploration of the Gulf Coast in 1747.
