  • A lease agreement approved between the GBRA and Thornton Family Investments, L.P. protects historic, senior water rights on the San Marcos River by assigning them to the Trust. This was a first for a Texas-based land trust. The initial lease period is five years. During this time, the rights will be held by the Trust and the water will remain in the San Marcos/Guadalupe Rivers for the benefit of all who use the river system. The Trust will make annual lease payments, and the lease period may be extended by both parties. The Thornton family are direct descendants of Ed Cape, who obtained these rights from the State of Texas between 1895 and 1905. These senior water rights are some of the oldest in the Guadalupe River Basin and amount to 70 acre feet of water per year, which is equivalent to almost 23 million gallons of water annually. As long as the San Marcos Springs are flowing, this water will be available.
