The river is primarily fed by rainfall in the surrounding area, with additional inputs coming from the San Antonio Springs and various small tributaries. The river passes through several major dams, including the Olmos Dam and the San Antonio River Basin Dam, which help regulate its flow. Seasonal trends show that the river tends to have higher flows in the spring and early summer months, with lower flows in the fall and winter. Interestingly, the river is home to a rare species of freshwater mussel, the Texas Pimpleback, which is considered endangered.
