The River Authority completed the predictive flood modeling system for Bexar County in 2021. The Downstream Predictive Flood Modeling project intends to extend the coverage of that system to Wilson, Karnes and Goliad Counties. The predictive flood modeling system provides real-time operational forecasting, early warnings, and important situational awareness during emergency response operations. River Authority staff plan to coordinate efforts for this project with staff from Wilson, Karnes and Goliad Counties as well as other key stakeholders.
Mission Reach Area Maintenance
January 15, 2026
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.
