High Plains Aquifer System Groundwater Availability Model (GAM)
In July 2012, the Texas Water Development Board (TWDB) contracted with INTERA, Inc. to develop a groundwater availability model (GAM) for the High Plains Aquifer System (Ogallala Aquifer, Dockum Aquifer, Edwards-Trinity (High Plains) Aquifer, and Rita Blanca Aquifer). The project was completed and delivered in 2015.
Model Report
"Conceptual Model for the High Plains Aquifer System Groundwater Availability Model."
"Numerical Model for the High Plains Aquifer System Groundwater Availability Model."
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.
Stakeholder Advisory Forums (SAF)
A Stakeholder Advisory Forum (SAF) was held on Thursday, September 19, 2024 to discuss an update to the groundwater availability model (GAM) for the High Plains Aquifer System which extended the model to cover the time period of January 1, 2013 through December 31, 2020.
For any questions or comments, please contact Tim Cawthon 512-463-5076.
The presentation slides and a video recording of the meeting are included in the table below.
