Abstract

The purpose of this report is to document information now available on Comal, San Marcos, and Hueco Springs, and to define the geologic and hydrologic conditions under which the springs occur. The need for the report has been occasioned by the planning activities underway by the Texas Department of Water Resources with respect to water suppl ies for the Guadalupe, San Antonio, and Nueces River basins. In their upper reaches, these three basins are crossed and hydrologically connected by the Edwards (Balcones Fault Zone) aquifer, which is the principal source of water supplies for Uvalde, Sabinal, Hondo, San Antonio, New Braunfels, San Marcos, and other users in this area. The aquifer receives water principally by infiltration from the streams which cross it. The water in the aquifer moves generally from west to east, across the lines of surface drainage divides, and is discharged through wells and springs en route. Comal, San Marcos, and Hueco Springs are in the eastern part of the aquifer in Comal and Hays Counties, and their flow comprises most of the natural discharge of the aquifer.
