Groundwater Management Area 16Groundwater Flow ModelThis map shows the extent and location of the Groundwater Management Area 16 Groundwater Flow Model.

The Groundwater Management Area 16 model includes portions of the underlying Gulf Coast, Yegua-Jackson, Queen City, Sparta, and Carrizo-Wilcox aquifer systems. The model was developed in an effort to provide results useful to Groundwater Management Area 16, because the existing groundwater availability models for the central portion of the Gulf Coast Aquifer and the southern portion of the Gulf Coast Aquifer do not individually encompass the footprint for Groundwater Management Area 16, nor do they include the Yegua-Jackson, Queen City, Sparta, or Carrizo-Wilcox aquifer systems. The purpose of this model, therefore, was focused on use as a tool in developing desired future conditions.

Work is underway to update the groundwater availability models for the Central and Southern sections of the Gulf Coast Aquifer. Please see the page for the Gulf Coast Aquifer System Groundwater Availability Model, which will include both GMAs 15 and 16.

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.
