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.

The Upper Guadalupe River Authority will host the 19th annual River Clean Up on Saturday, July 23, 2022 from 8 a.m. - 12 p.m. The headquarters for the Clean Up will be at Flat Rock Park in Kerrville.

Summer Bacteria Testing

The Summer Swimability Study monitors bacteria levels at popular swimming holes from Memorial Day to Labor Day.  UGRA staff collects samples from 21 sites throughout Kerr County during 15 consecutive weeks. The water samples are analyzed at the UGRA Environmental Laboratory for E. coli bacteria and the results are compared to guidelines for contact recreation.  Learn More
