Who Are the River Warriors

River Warrior volunteers are River Proud constituents of the San Antonio River Basin, ages 15 years and above, who believe in the San Antonio River Authority’s mission of safe, clean and enjoyable creeks and rivers.

River Warriors are interested in learning more about the San Antonio River Basin and sustainable practices to help area creeks and rivers, and they want to take action to help ensure a vibrant, thriving river basin for future generations.

River Warriors know that together we can make a difference and so they strive and donate their time and energies to achieve a shared vision.
