Please contact the GAM Section (512-936-0871) for a copy of 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 are only available as a package for the entire model area and require 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).
