Welcome to the UGRA
The Guadalupe River originates in Western Kerr County, deep in the Texas Hill Country. This beautiful spring fed river is one of the highest rated recreational and scenic rivers in Texas and is Kerr County's central asset.
The Upper Guadalupe River Authority (UGRA) was created as a conservation and reclamation district by the Texas Legislatures in 1939. In short, the mission of the Upper Guadalupe River Authority is to protect, develop, and manage the water quantity, quality, and sustainability in the Guadalupe River watershed in Kerr County.
