Welcome to The Story of Litter

What is The Story of Litter?

Do you want to teach your students where litter comes from, how it moves through and negatively impacts the environment, and how we can work together to solve this problem? Look no further than The Story of Litter!

The Story of Litter is a program developed by San Antonio River Authority educators and field tested by teachers. We’ve crafted resources that make teaching stewardship TEKS-aligned! Using the resources below, you can choose from a variety of ways to educate your students about litter and then plan a litter pickup on your school grounds to put their education into action!

Slide Decks and Videos

The Story of Litter Slide Decks: If you would like to personally present this information to your students, you can download this slide deck that will enable you to take your students through The Story of Litter from beginning to end. We have one version for elementary school students, and another version for middle and high school students.

The Story of Litter Videos: If you’d rather have a San Antonio River Authority educator teach your students about The Story of Litter, show your students this video! The content here matches the slide decks linked above, so there is no need to present both. Just like the slide deck, we have two versions for you to choose from according to your students’ grade level.

The Story of Litter Pledge

Once your students have learned about the ins-and-outs of litter, you can display this pledge in your classroom to remind them of how we can keep our land and water safe, clean, and enjoyable!

The restroom at Espada Park will be temporarily closed due to a water leak. Our team is working to resolve the issue as quickly as possible. We appreciate your patience and understanding!

Mission Reach Area Maintenance

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. Stem Density Map
