Central portion of the Gulf Coast Aquifer System Groundwater Availability Model (GAM)
Work is underway to update the groundwater availability models for both the Central and Southern sections of the Gulf Coast Aquifer. Please see the page for the Gulf Coast Aquifer System Groundwater Availability Model, which will include both GMAs 15 and 16.
The Texas Water Development Board (TWDB) contracted with Waterstone Environmental Hydrology and Engineering, Inc. (who was teamed with Intera, Inc., Parsons Engineering Science, Inc., and several individual experts) to develop a model of the central part of the Gulf Coast Aquifer in Texas.
TWDB staff has since recalibrated the central part of the Gulf Coast Aquifer while honoring historical pumpage (see below).

Model Files and Associated Data
Please see the GAM files download page for the current model files and associated data.
Aquifer data is only available as a package for the entire model area and requires GIS software for processing. Please see the GAM files download page for aquifer data.
