The San Antonio River and surrounding creeks have experienced devastating floods throughout the city's history. Major flooding in 1819, 1868, 1913, and 1921 caused extensive property damage and loss of life. An engineering study after the 1868 flood recommended construction of a dam in the San Antonio River basin north of the city. Over fifty years passed before this structure was completed and a flood bypass channel was built to protect the downtown area.

Vegetation removal, channel straightening, and small dams were also used to control flooding on the river and creeks. In the 1990s deep underground tunnels were built to carry floodwaters from the San Antonio River and San Pedro Creek past the downtown area. At this site the gate to the right of the locks controls the river's upper pool level, as well as river flow in times of flooding. This type of dam is called a crest gate dam.
