Two entities that spent years in litigation over Guadalupe River water use and how it affects the wintering population of the endangered whooping cranes are finding common ground and today announced that they are collaborating on a white paper.  This white paper, between the Guadalupe-Blanco River Authority (GBRA) and The Aransas Project (TAP), will bring the two parties together to address human and environmental issues for the benefit of the Guadalupe River system, including San Antonio Bay and Estuary, and to secure funding for studies related to this endeavor.
