Mission Reach Area Maintenance

February 6, 2026
*FEBRUARY 2026 UPDATE* Acequia Park Trailhead will be temporarily closed due to ongoing Stem Density work. The closure area includes the section south of Theo Avenue and Probandt Street, extending south to Mission Road. Currently, work is taking place only on the west bank. The east bank portion of the project has been completed. Trails will be reopened Thursday (02/05) through the weekend and will close again early Monday (02/09) morning. Ongoing work will take place from Monday mornings through late Thursday afternoons. We appreciate your patience as we complete this important work to maintain and improve the park area. 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.
Questions? Call the San Antonio River Authority at (210) 227-1373 or visit https://www.sariverauthority.org/services/river-health/ecosystems/. Thank you for your patience while we keep the Mission Reach safe, clean, and enjoyable. Mission Reach Trail Closure 2.3.2026
