Named for the river systems that flow into it, the Mission-Aransas reserve protects 185,708 acres of coastal prairie, oak motte, riparian freshwater, salt marsh habitat, tidal flats, seagrass beds, mangroves, and oyster reefs. The north side of the reserve is the winter home to the critically endangered whooping crane.

The Edwards Aquifer is a unique groundwater system and one of the most prolific artesian aquifers in the world. It is one of the greatest natural resources on Earth, serving the diverse agricultural, industrial, recreational, and domestic needs of almost two million users in south central Texas.

Established by the Texas Legislature, GBRA was first created in 1933 under Section 59, Article 16 of the Constitution of Texas as a water conservation and reclamation district and a public corporation called the Guadalupe River Authority. In 1935, it was reauthorized by an act of the Texas Legislature (VCS Art. 8280-106) as the Guadalupe-Blanco River Authority.
