Central portion of the Carrizo-Wilcox AquiferGroundwater Availability Model (GAM)
In 2015 the Texas Water Development Board (TWDB) contracted with INTERA Inc. (teamed with RW Harden and Associates, GSI Environmental Inc., Alan Dutton, Tom Ewing, and John Doherty) to evaluate faults in the central portion of the Carrizo-Wilcox Aquifer and improve their representation in the groundwater availability model for the Central portion of the Carrizo Wilcox, Queen City, and Sparta Aquifers. The project is expected to be completed Fall 2018.
Previously, the TWDB contracted with the Bureau of Economic Geology (which teamed with R.W. Harden and Associates, Inc., and HDR Engineering, Inc.) to develop a groundwater availability model of the central part of the Carrizo-Wilcox Aquifer in Texas. A final report and model were delivered in 2003.
This groundwater availability model has been superseded by the Carrizo-Wilcox, Queen City, Sparta Aquifers Groundwater Availability Model, which includes the Carrizo-Wilcox Aquifer. However, model users interested in details about the development of the Carrizo-Wilcox Aquifer Groundwater Availability Model should still refer to the groundwater availability model report (Version 1) listed below.

Model Report
Groundwater Availability Model for the Central Part of the Carrizo-Wilcox Aquifer in Texas.
Question and TWDB staff response from stakeholder review of draft report.
Model Files
The Carrizo-Wilcox Aquifer Groundwater Availability Models (all three portions) have been incorporated into the Carrizo-Wilcox, Queen City, Sparta Aquifers Groundwater Availiability Models. See the Carrizo-Wilcox, Queen City, Sparta Aquifers Groundwater Availability Models page for 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.
See the Carrizo-Wilcox, Queen City, Sparta Aquifers Groundwater Availability Models page for the model grid.
Aquifer Data
The Carrizo-Wilcox Aquifer Groundwater Availability Models (all three portions) have been incorporated into the Carrizo-Wilcox, Queen City, Sparta Aquifers Groundwater Availability Models. See the Carrizo-Wilcox, Queen City, Sparta Aquifers Groundwater Availability Models page for aquifer data.
