Water is vital to Nebraska. In fact, groundwater provides approximately 85 percent of the water used for human consumption in Nebraska.

About 65% of the High Plains Aquifer (also called the Ogallala Aquifer) lies beneath Nebraska and is estimated to contain about two billion acre-feet of water (an acre-foot being enough water to cover one acre of land with a foot of water, or about 326,000 gallons of water). This is equal to about 25 years of the state's average annual stream-flow or about 700 times the average amount of water in its surface water reservoirs.

Groundwater supplies drinking water for 51% of the total U.S. population and 99% of the rural population. (Nebraska Groundwater Foundation)

Groundwater helps grow our food: 64% of groundwater is used for irrigation to grow crops. (Nebraska Groundwater Foundation)

Agricultural producers are continuously improving their irrigation management of crops.
