Simulation of Streamflow and Estimation of Recharge to the Edwards Aquifer in the Hondo Creek, Verde Creek, and San Geronimo Creek Watersheds, South-Central Texas, 1951–2003

The Edwards aquifer is one of the most productive aquifers
in the United States and is the major source of public water supply
for San Antonio and numerous smaller municipalities in
south-central Texas. In addition, the Edwards aquifer supplies
large quantities of water for agriculture, industry, military
installations, and recreational activities. The aquifer also is a
source of water to major springs in the region. These springs
provide habitat for several threatened and endangered species
and supply water to downstream users.
