Region 13 Nueces Flood Planning Region

Region 13The Nueces River originates on the Edwards Plateau in Central Texas in Edwards and Real Counties. The Sabinal, Atascosa, Leona, and Frio Rivers and their numerous tributaries all feed the Nueces on its way to Nueces and Corpus Christi Bays. Extending south from Corpus Christi, a large portion of the Nueces-Rio Grande Coastal Basin, containing Corpus Christi Bay, Corpus Christi Ship Channel, Oso Bay, and Baffin Bay, is also located in the Nueces Flood Planning Region. This region includes six major reservoirs and crosses five ecoregions of Texas, including most of the South Texas Plains ecoregion.
