The Ogallala Aquifer (OA) underlies about 170,000 square miles (111 million acres) of Wyoming, South Dakota, Nebraska, Kansas, Colorado, Oklahoma, Texas, and New Mexico, including about 1.9 million acres of tribal lands and 2.9 million acres of federal lands. Water from the aquifer is vital to regional aquatic, riparian, range, and agricultural ecosystems.
