Region 11 Guadalupe Flood Planning Region
The Guadalupe River and its contributing creeks and streams flow from the Texas Hill Country as far west as Kerr County on its way to San Antonio Bay. The Comal, Blanco and San Marcos Rivers all feed the Guadalupe along this region. The adjacent San Antonio River flows into the Guadalupe just before it enters San Antonio Bay and the Gulf of Mexico. This region is home to five major lakes and reservoirs and crosses five diverse ecoregions.
