Lipan AquiferGroundwater Availability Model (GAM)

The Texas Water Development Board contracted with LBG-Guyton and Associates to develop a model for the Lipan Aquifer. The project was completed and delivered in 2005.

Model Files

Please contact David Thorkildsen (512-936-0871) for a copy of model files. The model files are available in an electronic format with a small processing fee per CD/DVD.

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. The raw/source data may be requested on CD(s) in an electronic format with a processing fee by contacting David Thorkildsen (512-936-0871).
