San Antonio Springs is the name of a cluster of springs in Bexar County, Texas, U.S.A. These springs provide much of the water for the San Antonio River, which flows from San Antonio to the Gulf of Mexico.
[edit] Geography
The San Antonio Springs are located about three miles (5 km) north of downtown San Antonio; most are now on the property of the University of the Incarnate Word. The springs are fed by water from the Edwards Aquifer; this water reaches the surface through faults along the Balcones Escarpment. There have been more than 100 individual springs identified, but many of these are no longer active due to pumping demands on the Edwards Aquifer and sedimentation from the upstream Olmos Creek. During periods of drought, the springs sometimes stop flowing entirely, only to resume when water levels rise in the aquifer. The mean flow from the springs is 20 ft³/s (0.6 m³/s).
[edit] History
Artifacts from Paleo-Indian cultures have been found at the site of the San Antonio Springs; some of these artifacts are more than 11,000 years old.
The earliest Europeans found up to 200 sub-bands of Coahuiltecan Indians in the vicinity of the springs; however, they were soon displaced by the Lipan Apaches. Spanish missionaries built a system of aqueducts and ditches to carry water from the springs to the local missions, including The Alamo.
By the Civil War, the springs had become contaminated. In the 1880s, artesian wells were drilled to provide clean water for the city.
