The High Plains aquifer components in Kansas are made up of the Ogallala, Great Bend Prairie, and Equus Beds regions as shown on the map below.

The High Plains aquifer underlies about 174,000 square miles of the central United States. It falls east of the Rocky Mountains in the southern part of the Great Plains. The aquifer underlies portions of eight states. They include 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.
