    Ways We Help

    The San Antonio River Authority is meeting the challenge of keeping lives, property, and our natural environment safe and secure with comprehensive planning, precision protection, strategic partnerships, and community preparedness.

    Along with maintaining over 40 dams and other flood control structures, the River Authority also advocates for development techniques designed to reduce runoff and improve water quality.
