What percentage of the high plains aquifer underlies Nebraska?

The high plains aquifer, also known as the Ogallala aquifer, is a vital source of groundwater in the central United States, particularly for agricultural purposes. In Nebraska, the aquifer plays a crucial role in providing water for irrigation and sustaining the agricultural economy of the region.

Approximately 85% of the high plains aquifer occurs beneath Nebraska. This significant percentage highlights the importance of responsible water management and conservation practices in Nebraska, as this aquifer serves as a critical resource for the state's farming and ranching activities. By acknowledging that a substantial part of the aquifer lies under Nebraska, it emphasizes the state's reliance on this groundwater source for its agricultural needs, and the potential impacts of over-extraction or contamination.

The other percentages presented in the choices represent lower estimates of the aquifer's coverage in Nebraska, which do not accurately reflect the geological and hydrological studies indicating that a more significant portion actually underlies the state. Understanding this percentage is vital for effective water resource management and promoting sustainable practices among agricultural stakeholders in Nebraska.
