These data were created as part of a hydrologic study to characterize groundwater budgets and water quality in the Diamond Valley Flow System (DVFS), central Nevada. This dataset represents 2011 irrigated agricultural lands and associated land disturbances in the DVFS. The locations of irrigated agricultural lands were interpreted using Landsat imagery from the summer of 2011, National Agricultural Imagery Program imagery from 2010, and well water use information from the U.S. Geological Survey National Water Information System. Some areas classified as agricultural lands may be irrigated using diverted surface water or springs. Associated disturbances are areas that have been or may have been disturbed as a result of current or past agricultural activities.
