The Guadalupe Basin Coalition represents a coalition of proud Texas businesses, lake associations, chambers of commerce, and governmental entities representing counties along the Guadalupe River Basin. GBC is driven by a common concern for the economic and environmental sustainability of the Guadalupe River Basin and San Antonio Bay.


United in our conviction that the springs must continue to flow.
