The Edwards aquifer is a karst aquifer system that is a primary water source for a large part of central Texas including the city of San Antonio, Texas. These vector geospatial data represent the geographic extent of the contributing zones for the Northern, Barton Springs, and San Antonio segments of the Edwards aquifer. The contributing zone is defined as the drainage area of the Edwards Plateau that contributes surface water to the Edwards aquifer recharge zone. The recharge zone is where surface water and precipitation infiltrate into the outcrop of the rocks that compose the aquifer (see Ashworth and Hopkins, 1995, and George and others, 2011).

The characteristics, discharge, and water quality of springs and seeps, at the Fort Irwin National Training Center (NTC) were evaluated during 2015 and 2016. Geophysical, hydrological, and water-quality data were used to help characterize and document a baseline of current (2016) hydrologic conditions and water quality of springs and seeps located on the NTC. Hydrologic methods used in this study included discrete discharge measurements to evaluate surface flow from the springs, and temperature measurements to trace groundwater movement beneath the springs. This data release contains discharge measurements and temperature data at four springs: Garlic, Bitter, Jack Spring East, and Jack Spring West.
