Nacatoch AquiferGroundwater Availability Model (GAM)This map shows the extent and location of the Nacatoch Aquifer Groundwater Availability Model.

In 2006, the Texas Water Development Board contracted with LBG-Guyton & Associates (who teamed with INTERA, Inc. and Dr. Graham Fogg) to develop a Groundwater Availability Model for the Nacatoch Aquifer. The project was completed and delivered in 2009.

Model Files

Please contact David Thorkildsen (512-936-0871) for a copy of the model files.

Model Grid

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

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 David Thorkildsen (512-936-0871).
