The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

The Ogallala aquifer is the principal source of water for agriculture in western Kansas. It’s not an underground lake as some believe but saturated sediments that have been deposited over the ...

[4]: 356 The Ogallala Aquifer is the main freshwater source for the region and consists of braided stream deposits filling in valleys during humid climatic conditions, followed by a sub-humid to arid climate and thick eolian (wind-blown) sand and silt. [4]: 356 Caliche layers cap the Ogallala, which reflect today's arid conditions.

The Ogallala aquifer, or the High Plains aquifer, is an integral fresh water source for the entirety of the Great Plains region, providing drinking water to 80% of the population and irrigating 13 million acres of land. Precipitation, seasonal lakes, and prehistoric water reserves serve as sources of water for the aquifer, which lies beneath ...
Hundreds of feet of younger sediment cover the White River group in southwest South Dakota. Miocene sandstones, which often form cliffs, often overlay the White River Formation. A period of erosion occurred in South Dakota during the Pliocene. Particularly in western South Dakota, the mobilization of coarse sediments formed the Ogallala aquifer ...
