Aquifers of Nebraska
There are at least seven major aquifer systems in Nebraska. By far, the High Plains/Ogallala aquifer is the largest in terms of volume of water in storage and withdrawals for irrigation. Several secondary aquifers exist in areas outside of the High Plains aquifer, providing water for irrigation, municipal supplies, and domestic use in parts of far western and far eastern Nebraska. The Conservation and Survey Division maintains an active research program aimed at characterizing the aquifers of Nebraska to provide information for well drillers, water managers, and the public.
