Yegua-Jackson AquiferGroundwater Availability Model (GAM)This map shows the extent and location of the Yegua-Jackson Aquifer Groundwater Availability Model.

In 2008 the Texas Water Development Board (TWDB) contracted with INTERA, Inc to develop a Groundwater Availability Model for the Yegua-Jackson aquifer. The project was completed and delivered in 2010.

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).
