The Guadalupe-Blanco River Trust (GBRT) is a 501(c)(3) nonprofit land trust organization that was developed to conserve land in the Guadalupe River Watershed for its natural, recreational, scenic, historic and productive value. It was founded in 2001 by the Guadalupe-Blanco River Authority (GBRA), a conservation and reclamation district created in 1933 by the Texas Legislature. The Upper Guadalupe River Authority (UGRA) has also partnered with the Trust. The voluntary board of directors consists of citizens who share a love of the Guadalupe River - one of the most pristine rivers in Texas.
