Ogallala Aquifer Maps and Data

The Ogallala Aquifer provides water resources for the extensive agricultural assets and population of West Texas and the Great Plains. Therefore, the Center for Geospatial Technology has developed a GIS repository of data and map products for researchers to better understand, to help preserve, and to protect this valuable resource.

This website is organized into two parts: 1) Ogallala Maps & Data and 2) Texas Maps.  The Ogallala Maps & Data section contains aquifer information for forty-one Texas counties for a nineteen year study period from 1990 to 2008.  Included in the Texas Counties subsection are maps and graphs of the water in storage, change in water in storage, the saturated thickness, and the change in saturated thickness for each county.  Additionally summary data and graphs by county present the available water in storage and average saturated thickness.  The Texas Ogallala Summary subsection presents summary data and maps for the portion of the aquifer that lies within Texas

The Texas Maps section of the atlas provides an information resource of the land, the people, and the agricultural economy of the region that is served by the Ogallala Aquifer and compares that to the rest of the state. The Texas Maps section is organized into three categories: Agriculture, Demographic Trends and Physical Landscape.  Also provided is a description of each map including the source data information.  All maps are provided in PDF format.

The goal of this project is to provide scientifically sound data and knowledge to water planners and policymakers to support the decision making that will ultimately affect the longevity of Ogallala Aquifer.

The efforts in this project were funded by the United States Department of Agriculture, Agricultural Research Service as part of the Ogallala Aquifer Program.
