Ogallala aquifer



The Ogallala aquifer is one of the largest known aquifers (also known as the High Plains Aquifer) The Ogallala is an ancient, non-replenishing body of water that supplies nearly one third of the water used for irrigation in the United States. The aquifer lies beneath 8 states in the U.S. and occupies some 175,000 square miles. More than 5 trillion gallons of water are pumped from the aquifer each year. These large underground aquifers may represent remnants of the subterranean waters that burst forth during the global flood.
