This dataset consists of point gravity station data for 95 stations in the middle Carson River basin as published on figure 7 in the U.S. Geological Survey Scientific Investigations Report 2011-5055. The points have values of the complete Bouguer anomaly and observed gravity. In addition, 641 selected gravity stations from the U.S. Geological Survey Data Series 42 titled "Gravity data of Nevada" used in this study are included for reference and users are advised to reference that publication for information on those data.

This dataset consists of polyline estimates of the thickness of basin-fill sediments at 200-foot contour intervals for the middle Carson River basin as published on figure 9 in the U.S. Geological Survey Scientific Investigations Report 2011-5055. The estimates were made using gravity data collected at 736 stations in the middle Carson River basin reduced to a residual complete Bouguer anomaly. A relation between residual gravity and depth to bedrock was developed from descriptions on drillers logs of 25 wells that encountered bedrock.

This data collection consists of a synthetic stream network and associated catchments developed as the foundation for a Spatially Referenced Regressions on Watershed Attributes (SPARROW) dissolved-solids source and transport model for the Upper Colorado River Basin (UCRB). The SPARROW model requires a hydrologically connected representation of a stream network through which loads are transported from an upstream reach to the next reach downstream (Schwarz and others, 2006; Moore and others, 2004). Each stream reach or segment within this synthetic stream network has an associated local drainage area or catchment used to calculate catchment characteristics that may have an effect on loads being modeled. The synthetic...

This dataset consists of points representing selected well site locations and water-level measurements used by Lopes and Allander (2009) to develop autumn 2006 groundwater-level altitude contours for Smith and Mason Valleys, and the lower Walker River basin, Nevada. Since the publication of Lopes and Allander (2009), the positional coordinates and land-surface altitudes at selected well sites used to develop autumn 2006 groundwater-level contours in that report were updated as part of a 2022 U.S. Geological Survey study (Davies and Naranjo, 2022).

This data set consists of polylines representing groundwater-level altitude contours, 1982, for middle Humboldt River basin, north-central Nevada as published on plate 2, figure 3 in the U.S. Geological Survey Water-Resources Investigations Report 98-4209 titled "Hydrogeologic framework and ground-water levels, 1982 and 1996, middle Humboldt River basin, north-central Nevada," 1999. A subset of the contours were published as part of a larger data set representing water-table contours for Nevada (Buto and others, 2006). The remaining contours have been added to complete this data set.

These contours represent static groundwater levels based on depth-to-water measurements made at 165 monitoring wells during water years 2016-2020 in Smith Valley and Mason Valley, Nevada. For each monitoring well, the median groundwater-level altitude during the five-year period (2016-2020) was used for developing the groundwater-level contours. Depth-to-water measurements were collected by the USGS and the Nevada Division of Water Resources (NDWR).

This polygon shapefile represents model simulated flood-inundation extents for the Muddy River, near Moapa Nevada. A flood frequency analysis was performed at USGS streamgage 09416000 - Muddy River near Moapa, Nevada, to estimate the 50, 20, 10, 4, 2, and 1-percent annual exceedance probability (AEP) flood streamflows. The flood-inundation extents for the 50-, 20-, 10-, 4-, 2-, and 1-percent AEP floods were simulated for the current levee location in 2019 and for the new levee location of the proposed restoration. One model simulation represents the levee at its current (existing) location in 2019 on the east bank of the river and referred to as ‘current conditions (2019).’ A second model simulation removes the...

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 dataset consists of 1:500,000-scale polygons of geologic units grouped into hydrogeologic units and estimated specific yield ranges for the easternmost 4–5 miles of the middle Carson River basin as published on figure 3 in the U.S. Geological Survey Scientific Investigations Report 2011-5055. This dataset does not extend to the western side of the study area. The dataset titled "1:100,000-scale hydrogeologic units and estimates of specific yield, western part of middle Carson River basin, Nevada (from U.S. Geological Survey Scientific Investigations Report 2011-5055, figure 3)" was used for the western part of the study area.

This dataset represents one of three derived outlets or "pour points" for each 12-digit hydrologic unit (HU12) in the Watershed Boundary Dataset (WBD) snapshot delivered with NHDPlus V2.1. The three related pour point locations, each delivered in a stand-alone dataset, are: "from" (fpp) and "to" (tpp) points that identify the location where flow leaves the HU12 polygon based on a flow direction raster, and a third "vector pour point" (vpp) selected "upstream" used to identify flow confluences near the "from" and "to" pour point locations. The points are derived from the NHDPlus V2.1 flow direction rasters and the WBD snapshot delivered with NHDPlus V2.1. This metadata document describes the "vector" pourpoints (vpp).

These contours represent water level change in the shallow aquifer in Lahontan Valley from 1992 - 2012 based on depth-to-groundwater measurements made in 73 wells in 1992 and 2012, with limited measurements made in 2013. Measurements collected in 2013 were used to develop the contours only in limited cases where the measurement well was being pumped or was inaccessible in 2012. Water-level change in the shallow aquifer was determined by differencing measurements made in 1992 with current measurements. The difference values were used to interpolate a change surface and contours were developed from that surface.
