The river is also important for agriculture and recreation. The gauge records flow data throughout the year, with the highest flows typically occurring in the spring due to increased precipitation and spring runoff. There are several tributaries that contribute to the San Antonio River, including the Medina River and the Guadalupe River. The Riverwalk, a popular tourist attraction in San Antonio, is fed by the San Antonio River. The San Antonio River Authority manages the river's water supply and conducts conservation and restoration efforts to maintain the river's ecological health.
