Ground-Water Information and Data

How regional aquifers respond to changes in climate and stresses to the aquifer system, such as pumping over long periods of time, is largely unknown in Nevada. Understanding, planning, and managing Nevada’s water resources requires long-term data to define trends, uncover issues, and take corrective actions. Ground-water data are collected from regionally representative well networks that allow for the measurement of water levels in most aquifers within the State. Measurements of recharge to, and discharge from, ground-water systems provide data to assist in evaluating the effects of managing, developing, and determining future water supplies.

Continuous well measurements are made at more than 15 wells throughout the State. Periodic well measurements are made at more than 800 wells but the number of wells can vary from year to year. Periodic measurements are made at approximately the same times each year to reduce seasonal effects. Water-quality data are collected at more than 130 wells and can vary depending on project needs. New wells are added to the network as old wells are destroyed, local land use changes, and other needs arise.
