An Introduction to Watershed Sustainability

Think for a moment about the word sustainability. What comes to mind? For many people, environmental sustainability means recycling, conserving energy and water, or reducing air pollution. All of these things are essential in creating a healthy environment that can be sustained for generations to come. However, maintaining clean and healthy water in our creeks and rivers is also an essential element of environmental sustainability.

How the River Authority Defines Sustainability

The San Antonio River Authority (River Authority) is dedicated to achieving a sustainable watershed through improving water quality in the San Antonio River Basin. We believe that sustainability is achieved by implementing solutions that balance a set of criteria that is often referred to as “the triple bottom line.” To meet these criteria, sustainability solutions must:

People, Profit, Planet Graphic

How we care for our watershed now will determine the health of rivers and streams for future generations to enjoy. Polluted San Antonio River water harms more than just the fish and wildlife in our local area. Water that drains into the San Antonio River flows all the way to San Antonio Bay where it has direct impact on the health of wildlife in the bay and the Gulf of Mexico.

However, a sustainable watershed is not just good for the environment. In the long run, it will save taxpayer money through reduced infrastructure costs. It will also improve quality of life in our watershed through increased green space, walkability, and landscape beautification.

If we do not take steps now to encourage a healthy watershed, we could be susceptible to federal government intervention in the future. We feel that it is important for the community, not the federal government, to be responsible for decisions made about the river.

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.
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.
