Carrizo-Wilcox, Queen City, and Sparta aquifers Groundwater Availability Models (GAM)
The Carrizo-Wilcox, Queen City, and Sparta aquifers groundwater availability model supersedes existing Carrizo-Wilcox Groundwater Availability Model for the southern portion of the Carrizo-Wilcox Aquifer. However, in the central and northern areas this model is superseded by the newer Groundwater Availability Model for the central portion of the Carrizo-Wilcox Aquifer and by the newer Groundwater Availability Model for the northern portion of the Carrizo-Wilcox Aquifer.
The Texas Water Development Board contracted with INTERA Inc. (teamed with the Bureau of Economic Geology, and Brandeis and Associates) to add the Queen City and Sparta aquifers as additional layers to the existing three Carrizo-Wilcox models. The project was completed and delivered in 2005.
