The High Plains aquifer underlies about 174,000 square miles underling portions of eight states--South Dakota, Wyoming, Nebraska, Colorado, Kansas, Oklahoma, New Mexico and Texas. The High Plains aquifer is the shallowest and most abundant source of water in the region. It allows the local economy to depend upon it for irrigated agriculture. The Ogallala formation is the principal geologic unit in the High Plains aquifer. It accounts for approximately 134,000 square miles of the High Plains aquifer. The Ogallala-High Plains aquifer is the dominant, often sole, source of water in western Kansas. The majority of the aquifer is under the management of Groundwater Management Districts No. 1, No. 3 and No. 4. The Basin Management Team also addresses the fringe areas outside of these districts. The goal of the Team is to conserve and extend the life of the Ogallala-High Plains aquifer through management by aquifer subunits, targeting water conservation activities to high priority subunits, improved characterization of the aquifer, and implementing strategies for improved agricultural practices with limited water resources. This collection contains relevant documents such as annual field summaries, management plans, and newsletters.
