The Texas Water Development Board has developed a groundwater availability model of the eastern arm of Capitan Reef Complex Aquifer. The numerical and conceptual model reports are available at the links below.

Conceptual Model Report

"Conceptual Model Report: Capitan Reef Complex Aquifer"

The geodatabase containing the source data files are available upon request and will be provided through a web transfer.

Model Files

Please contact the GAM Section (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 the GAM Section (512-936-0871).
