San Antonio segment of the Edwards (Balcones Fault Zone) Aquifer Groundwater Availability Model (GAM)
The U.S. Geological Survey in cooperation with the U.S. Department of Defense and the Edwards Aquifer Authority (EAA) have developed a GAM for the San Antonio segment of the Edwards Aquifer. However, the Texas Water Development Board will continue to maintain GWSIM as a model with an alternative hydraulic conductivity distribution and as an easier-to-use screening tool.

Please contact the GAM Section (512-936-0871) for a copy of the model files.
Model grid cells are geographically assigned to counties, groundwater conservation districts, river basins, groundwater management areas, and regional water planning areas within the model study area using a centroid based approach. The model grid is available in ESRI® shapefile format and comma-delimited text file.
Aquifer data is only available as a package for the entire model area and requires GIS software for processing. Due to the size of raw/source data files for this model, this information has not been posted on the web. To request the raw/source data, contact the GAM Section (512-936-0871).
