Be River Proud

Bays & Estuaries

While most people are aware of the San Antonio Riverwalk, few realize the San Antonio River actually flows 240-miles southeast from its headwaters in central San Antonio. It merges with the Guadalupe River and these combined waters empty into the San Antonio Bay on the South Texas coast.

Our River Flows to It

One important reason the San Antonio River Authority is committed to safe, clean, enjoyable creeks and rivers in our watershed is because the river’s health has a direct effect on the well-being of the bays and estuaries along the Texas coast.

The San Antonio River Authority is one of many stakeholders who are committed to working in partnership with others to protect and enhance the San Antonio Bay and surrounding estuary systems.
