The groundwater discharge area (GDA) in Tule and part of Sevier valley represents the area where discharge from evaporation by open water or bare soil and transpiration from phreatophytic plants exceeds the volume of water contributed by precipitation. The GDA was delineated during field reconnaissance of the study area using techniques similar to those used in previous studies throughout Nevada and eastern Utah.

This USGS data release, supporting USGS Scientific Investigations Report 2020-5075, Estimates of Groundwater Discharge by Evapotranspiration, Stump Spring and Hiko Springs, Clark County, Southern Nevada, 2016–18, consists of five datasets - Normalized Difference Vegetation Indexes (NDVI) and a mapped groundwater discharge areas (GDA) for two spring areas, and a two-class land cover classification for Stump Springs and the Area of Critical Environmental Concern (ACEC) adjacent to Stump Springs. The mapped GDAs are the area within each spring’s riparian area where discharge from evaporation by open water or bare soil and transpiration from phreatophytic plants exceeds the volume of water contributed by precipitation....

This dataset, created in support of USGS Scientific Investigations Report 2020-5075, Estimates of Groundwater Discharge by Evapotranspiration, Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18, represents a Normalized Difference Vegetation Index calculated for vegetated areas in the Hiko Springs groundwater discharge area. Vegetated areas within the GDA are composed of phreatophytic shrubs interspersed with xeric vegetation and bare soil. The GDA was delineated by visual interpretation of 1-meter National Agriculture Imagery Program (NAIP) aerial imagery acquired in May of 2015. Areas of channel scour within the GDA resulting from a flood event in September 2015 were delineated from a 2016 1.84-meter...

A three-dimensional MODFLOW-NWT groundwater flow model was developed to evaluate the impacts of alternative water management scenarios on the groundwater resources of Eagle, Dayton, and Churchill Valleys, Nevada. In addition, the resulting impact on flows in the Carson River and Lahontan Reservoir are also evaluated. During the economic boom that occurred from 2004-2006 in northwestern Nevada, municipal and housing growth increased stress on the limited water resources of this semi-arid region. In 2008, when the economy slowed, new housing development stopped, and immediate pressure on finite groundwater resources abated. In anticipation of economic recovery and resumed growth, however, the U.S. Geological Survey...

The mean MSAVI image is based on two Landsat 5 Thematic Mapper (TM) scenes representing midsummer conditions in 2007 and 2008. MSAVI was calculated for each image which were then combined by calculating the mean for each pixel in the scenes. The resultant MSAVI image was used to estimate vegetation assemblages (ET units) within a mapped groundwater discharge area.
