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).

Aquifers of the United States Withdrawal rates from the Ogallala Aquifer.. This is a list of some aquifers in the United States.. Map of major US aquifers by rock type. An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to groundwater wells and springs.
The Sandhills sit atop the massive Ogallala Aquifer; thus both temporary and permanent shallow lakes are common in low-lying valleys between the grass-stabilized dunes prevalent in the Sandhills. [4] The eastern and central sections of the region are drained by tributaries of the Loup River and the Niobrara River , while the western section is ...

The Ogallala Aquifer was formed more than 25,000 years ago, but it recharges at a very low rate. For years, irrigators in Kansas have drained more from the aquifer than rainfall can replace.
The Ogallala Aquifer is one of the world's largest aquifers spanning almost the entire state of Nebraska, except for a small section of the Nebraska Panhandle and areas in the east near the Missouri River. Nebraska hydrogeology is known through extensive irrigation well drilling for agriculture.
