The Texas Instream Flow Program (TIFP), jointly administered by Texas Commission on Environmental Quality, Texas Parks and Wildlife Department, and Texas Water Development Board, has initiated a study of instream flows necessary to support a sound ecological environment in the Lower San Antonio River. The TIFP seeks to incorporate stakeholder input, insight, and concerns while conducting this study. With the assistance of the San Antonio River Authority, initial stakeholder meetings were held in February 2005. Additional stakeholder input and assistance is required at this time in order to develop a study design for the basin. The TIFP will be holding stakeholder update meetings and study workgroup meetings in the San Antonio River Basin from July 2008 to June 2009. The assistance of the San Antonio River Authority is sought in order to develop the stakeholder process in this sub-basin and provide administrative and organizational support for these meetings.

Mission Reach Area Maintenance
Mission Reach Area Maintenance
*MARCH 2026 UPDATE*
Ongoing stem-density maintenance is currently taking place in this area. Crews will be working Monday through Friday during daytime hours. We appreciate your patience as we complete this important work to maintain and enhance the park for everyone to enjoy.
When: Beginning October 20, 2025 through Spring 2026
What: Crews will be performing stem-density removal and related vegetation maintenance along sections of the Mission Reach to help manage flood risk and protect surrounding infrastructure. Some trails or segments may be closed temporarily while work is underway.
Why: Removing excess stems that naturally establish along the river helps maintain stormwater conveyance, reduces flood risk, and protects public infrastructure while allowing grassland and native vegetation to recover and thrive.
What to expect:
- Limited trail closures and intermittent work zones.
- Crews and equipment working near the riverbanks during daytime hours.
- Parking areas remain open, but visitors may see signage and temporary barriers.

Thank you for your patience while we keep the Mission Reach safe, clean, and enjoyable.
