This data release consists of a Microsoft® Access database and Microsoft® Excel workbook that contain water-level data and other hydrologic information for wells in and near areas of underground nuclear testing at the Nevada Test Site (currently called the Nevada National Security Site). The database provides information for each well (well construction, borehole lithology, units contributing water to the well, and general site remarks) and associated water-level measurements (measurement source, status, method, accuracy, and specific water-level remarks). Additionally, the database provides hydrograph descriptions that document the water-level history and describe and interpret the water-level hydrograph for each...

This digital raster dataset represents depth to pre-Cenozoic bedrock in northern Nevada as published in Chapter 6: Geophysical Methods and Application in U.S. Geological Survey Bulletin 2218, Assessment of Metallic and Mineral Resources in the Humboldt River Basin, Northern Nevada by D.A. Ponce. The data are represented on figure 6-9 in this publication and were later provided as raster format geospatial digital data via written communication from D.A. Ponce in 2007. The data have been reprojected but are otherwise as provided. A thorough explanation of the production methods is available in the larger work.
Two-dimensional variably saturated heat and flow models (VS2DH) were used to examine seepage rates along the Birdspring drainage for the purpose of exploring the drainage channel for use in an managed aquifer recharge project. Six transect models were separately calibrated to sediment temperatures observed during episodic runoff events during water year 2017 and 2018. The models were calibrated to unsteady flow conditions, then estimates of seepage losses were made for steady state conditions assuming stage conditions associated with 4 cubic feet per second of imported water. This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report...

Selected evapotranspiration data were collected from 7/5/2011 to 1/1/2017 at the Amargosa Desert Research Site (ADRS, https://nevada.usgs.gov/adrs/) in support of ongoing research to improve the understanding of hydrologic and contaminant-transport processes in arid environments. The data presented in this data release includes 30-minute and daily evapotranspiration and associated energy-balance fluxes, precipitation, soil water content, air and soil temperature, wind speed and direction, humidity, and photosynthetically active radiation. Data methods follow those described in Moreo and others (2017). This is the third in a series of three releases of evapotranspiration data, which has been measured continuously...

This data release describes micrometeorological and soil-moisture data collected from January 1, 2017 through May 31, 2019 at the Amargosa Desert Research Site adjacent to a low-level radioactive waste and hazardous chemical waste facility near Beatty, Nevada. Micrometeorological data include precipitation, solar radiation, air temperature, relative humidity, saturated and ambient vapor pressure, wind speed and direction, barometric pressure, and soil-water content. Soil-moisture data include periodic measurements of volumetric water-content at four experimental sites that represent vegetated native soil, devegetated native soil, and two simulated waste disposal trenches—maximum measurement depths range from 5.25...

The USGS and Newmont Mining Corp. surveyed 51 cross sections to determine hydraulic characteristics throughout 12 model reaches. The accuracy of the surveyed cross sections is believed to be +/- 0.5 ft. Field surveys included measuring the channel cross section up to the approximate altitude of the highest flood and includes auxiliary channels. Surveyed cross sections generally were at representative locations about every 3 miles along the Humboldt River channel. In areas where long overbank sections occurred, supplemental altitudes were determined from topographic maps in order to extend surveyed parts of cross sections so that each section represented the full width of the floodplain. In this dataset there is...
This USGS data release represents supplemental tabular data for an annual groundwater discharge by evapotranspiration (ET) from areas of spring-fed riparian vegetation, Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18. The raw ET dataset contained multiple data gaps that were simulated and gap-filled with the water-level model utility in SeriesSEE, a USGS developed Microsoft Excel® addin. Continuous time-series data, including net radiation, sensible-heat flux, latent-heat flux, and ground-heat flux, from before and after the data gap(s) were used to simulate turbulent fluxes with multivariate regressions and the gramma transform, used for latent heat gaps after precipitation events. ET data were gap...

These data comprise the target and non-target VOC measurements collected from 1999 to 2016 from the shallow and deep unsaturated zone at the Amargosa Desert Research Site adjacent to a low-level radioactive waste and hazardous chemical waste facility near Beatty, Nevada. All data are compiled in electronic text files that are included with this release.
This USGS data release contains the regional potentiometric contours representing the regional potentiometric surface for Clark County, Nevada, 2009-2015. Contours represent the groundwater-level altitude with a 250-foot contour interval and were created from groundwater elevations from 58 wells and surface elevations from 5 springs.

This data release supports U.S. Geological Survey (USGS) Scientific Investigations Report 2023-5106, Groundwater Discharge by Evapotranspiration from the Amargosa Wild and Scenic River and Contributing Areas, Inyo and San Bernardino Counties, California. It consists of two comma-separated values (CSV) files containing data collected at two USGS atmospheric monitoring locations (USGS site identification numbers 355846116160401 and 355918116161801) beginning in January 2018 and lasting for approximately 1 year. The data include 30-minute values for cumulative normalized flux for 6 circular areas around each site and 30-minute values for unadjusted total evapotranspiration. The radii of the circular areas are 25, 50,...

Stakeholder science needs were determined by reviewing more than 200 recently published literature items and web pages from Colorado River Basin (CRB) stakeholders. These stakeholder communications were used to characterize over 400 stakeholder science needs by reviewing their priorities, strategies, issues, missions, and concerns related to drought in the CRB. Members of the CRB Integrated Science Pilot Project team identified each of the stakeholder’s science needs and categorized the needs based on science themes and science topics that the needs address in the landscape. The terms used as science topics were initially created by Pilot Project team members but then later were cross-walked to match terms in the...
This vector line dataset represents the lower Las Vegas Wash study area. Surface-water trace was digitized onscreen from Landsat8 and ESRI World Imagery. The trace is used in an accompanying surface-water study to evaluate discharge gains and losses at selected locations in the Lower Las Vegas Wash.

These data represent the extent and spatial distribution of irrigated acreage delineated from maximum Normalized Difference Vegetation Index (NDVI) derived from Landsat scenes in the Walker River Basin, California and Nevada, at five-year intervals from 1975-2010. The field boundaries in this data set are digitized from one-year composite maximum NDVI data derived from atmospherically corrected Landsat 2 Multispectral Scanner (MSS), Landsat 5 MSS, and Landsat 5 Thematic Mapper (TM) scenes. NDVI was calculated from the corrected reflectance data for each selected scene during the growing season (May through early October) and a single, composite image of maximum NDVI values was derived for each 5-year interval. Selecting...
