Instream Flows Study of the Lower San Antonio River and Lower Cibolo Creek – Interim Progress Report and Instream Flow Recommendations

In 2001, the 77th Texas Legislature enacted Senate Bill 2 establishing the Texas Instream Flows Program (TIFP). The purpose of this program is to perform scientific studies to determine the timing and flow requirements necessary to maintain a sound ecological environment in Texas Rivers. The State Legislature tasked the Texas Parks and Wildlife Department, Texas Commission on Environmental Quality and the Texas Water Development Board to work with stakeholders to develop instream flow recommendations that will maintain a sound ecological environment for both the instream and riverine habitats. The San Antonio River Authority has been working with the State Agencies on the Lower San Antonio River and Cibolo Creek Instream Flows Program. Technical data collected and evaluated to date, are presented in the report below: Instream Flows Study of the Lower San Antonio River and Lower Cibolo Creek – Interim Progress Report and Instream Flow Recommendations.
