High Plains Aquifer SystemGroundwater 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.
Please contact the GAM Section (512-936-0871) for a copy of the model files.
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 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 the GAM Section (512-936-0871).
