This project develops a future condition model and updates priority subbasins with the latest watershed information. Priority subbasins are based on ultimate buildout land use and are defined as subbasins where mitigations and/or conservation needs to occur for the streams to meet future water quality standards. The products of this work are valuable in informing the community as to where Best Management Practices (BMP’s) need to occur. It is also beneficial to the various efforts that are being planned on the Upper San Antonio River watershed, such as the efforts on West Side Creeks, and Brackenridge Park.

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.
