Seymour and Blaine aquifersGroundwater Availability Model (GAM)This map shows the extent and location of the Seymour and Blaine aquifers Groundwater Availability Model.

The Texas Water Development Board (TWDB) contracted with Intera, Inc. (who was teamed with Water Prospecting and Resource Consulting LLC, Parsons Engineering Science Inc., Enprotec Inc., and several individual experts) to develop a model of the Seymour Aquifer in Texas. The model includes the Blaine Aquifer as a lower layer. The model was completed in 2004.

In 2008, the Texas Water Development Board (TWDB) contracted again with Intera, Inc. (teamed with The Bureau of Economic Geology and Water Prospecting and Resource Consultants, LLC) to develop a refined model for the Seymour Aquifer in Knox, Haskell, and Baylor counties. The conceoptual model was completed in 2012. The Texas Water Development Board has developed a refined groundwater availability model for the Seymour Aquifer in Knox, Haskell, and Baylor counties based largely on the conceptual model developed by INTERA, Inc. The project was completed in early 2014.

A refined groundwater availability model for the island of the Seymour Aquifer located in Haskell, Knox, and Baylor counties is currently under development. See this page for more information.

Model Files

Please contact David Thorkildsen (512-936-0871) for a copy of the 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.

Aquifer Data

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 David Thorkildsen (512-936-0871).
