Davies Ramon C. Naranjo 2022 document Scientific Investigations Report 2022-5123 https://doi.org/10.3133/sir20225123 This raster dataset represents groundwater-level change from 2007 to 2020 in Smith Valley and Mason Valley, Nevada, calculated using approach 1. For this approach, groundwater-level contours from 2006 and 2020 were interpolated into rasters and differenced to calculate groundwater-level change. These datasets were created as part of a 2022 cooperative study by the U.S. Geological Survey with the Bureau of Reclamation and U.S. Bureau of Indian Affairs. The purpose of the study was to examine the effects of pumping on groundwater storage and stream efficiency of the Walker River in Smith Valley and Mason Valley, Nevada. The intended uses of this dataset include, but are not limited to, natural resource modeling, mapping, and visualization applications. 20061231 20200930 ground condition Complete None planned -119.4267 -119.0113 39.1804 38.7068 ISO 19115 Topic Category inlandWaters geoscientificInformation None Groundwater Water-level change USGS Thesaurus groundwater USGS Metadata Identifier USGS:61f4270dd34e622189bb482b None Smith Valley Mason Valley Smith Yerington Lyon County Nevada Great Basin None.

Carson City NV 89701 USA (775) 887-7600 GS-W-NVcrs_Webmaster@usgs.gov Compilation of this dataset and the associated metadata was done in cooperation with the Bureau of Reclamation and the U.S. Bureau of Indian Affairs. Version 6.2 (Build 9200); Esri ArcGIS 10.7.1.11595 No formal attribute accuracy tests were conducted. Verification was done by interactive on-screen review. Tests of valid values were performed throughout processing. Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. No formal horizontal positional accuracy tests were conducted on water-level change rasters. Horizontal positional accuracy depends on the horizontal accuracy of input water-level contours and the automated interpolation process used to interpolate contours to rasters. The input water-level contours were interpolated to produce 30-meter rasters. The data were visually inspected to confirm that pixel size did not negatively influence horizontal accuracy. No formal vertical positional accuracy tests were conducted on water-level change rasters. Vertical positional accuracy depends on the vertical accuracy of input water-level contours and the automated interpolation process used to interpolate contours to rasters. The input water-level contours were interpolated to produce 30-meter rasters. The data were visually inspected to confirm that pixel size did not negatively influence vertical accuracy. Davies, G.D.

Naranjo, R.C. 2022 Spatial information https://doi.org/10.5066/P9LI9XY7 online 2020 ground condition Common Extent Spatial information Approach 1: Source inputs sir20225123_SmithMason_wla_2006 and sir20225123_SmithMason_wla_2020 were interpolated into 30-meter rasters using the Esri ArcGIS Topo to Raster Spatial Analyst tool with default setting. The interpolation bounding extent was set to the following dimensions: Top = 4341142.584100 m, Right = 329761.696600 m, Bottom = 4281029.130500 m, Left = 286793.277400 m. This was to ensure interpolation on the fringes of the extent were not biased by the Common Extent source input boundary. The resulting rasters were clipped to the Common Extent source input using the Esri ArcGIS Extract by Mask Spatial Analyst tool. The clipped rasters were differenced using the Esri ArcGIS Raster Calculator Spatial Analyst tool with the raster interpolated from the sir20225123_SmithMason_wla_1970 source input as the snap raster. sir20225123_SmithMason_wla_1970 sir20225123_SmithMason_wla_2006 sir20225123_SmithMason_wla_2020 Common Extent 20210928 2007-2020 water-level change approach 1 Raster Grid Cell 1725 1159 1 Universal Transverse Mercator 0.9996 -117.0 0.0 500000.0 0.0 coordinate pair 0.6096 0.6096 meter North_American_Datum_1983 GRS_1980 6378137.0 298.257222101 National Geodetic Vertical Datum of 1929 10 Feet Attribute values sir20225123_SmithMason_wl_change_2007-2020_m1.tif TIF raster dataset User-defined Value Groundwater-level change in feet User-defined -195.6484375 63.099609375 feet U.S. Geological Survey - ScienceBase Mailing and physical address
