The Ogallala aquifer is an important water resource for the Rosebud Sioux Tribe in Gregory and Tripp Counties in south-central South Dakota and is used for irrigation, public supply, domestic, and stock water supplies. To better understand groundwater flow in the Ogallala aquifer, conceptual and numerical models of groundwater flow were developed for the aquifer. A conceptual model of the Ogallala aquifer was used to analyze groundwater flow and develop a numerical model to simulate groundwater flow in the aquifer.

Simulated hydraulic heads were within plus or minus 25 ft of observed values for 95 percent of wells, and the average absolute difference was 6.46 ft. The model can be used as a tool to assess the response of the aquifer to additional stresses, including increased withdrawals for irrigation or other uses.
