This dataset consists of a polyline representing a groundwater divide for spring 1972, Smith Valley, Nevada digitized from plate 2 of the 1976 publication: Rush, F.E.,and Schroer, C.V., 1976, Geohydrology of Smith Valley, Nevada with special reference to the water-use period 1953-72: Nevada Department of Conservation and Natural Resources Water Resources Bulletin 43, 43p.

This dataset consists of polylines representing groundwater-level altitude contours for spring 1972, Smith Valley, Nevada, digitized from plate 2 of the 1976 publication: Rush, F.E.,and Schroer, C.V., 1976, Geohydrology of Smith Valley, Nevada with special reference to the water-use period 1953-72: Nevada Department of Conservation and Natural Resources Water Resources Bulletin 43, 43p.

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.

Abstract To aid in parameterization of mechanistic, statistical, and machine learning models of hydrologic systems in the contiguous United States (CONUS), flow-conditioned parameter grids (FCPGs) have been generated describing upstream basin mean elevation, slope, land cover class, latitude, and 30-year climatologies of mean total annual precipitation, minimum daily air temperature, and maximum daily air temperature. Additional datasets of upstream basin area and binary stream presence-absence are provided to help validate queries against the flow-conditioned data. These data are provided as virtual raster tile (vrt) mosaics of cloud optimized GeoTIFFs to allow point queries of the data (see Distribution Information)...

These contours represent water levels based on depth-to-groundwater measurements made at 98 wells in July of 2012 in the Lahontan Valley near Fallon, NV. Water level measurements collected before or after July of 2012 were included only in cases where the well was being pumped or was inaccessible in July 2012. The contours were developed to compare with 1992 water level altitude contoured by Seiler and Allander (1993).

This data set consists of 1:500,000-scale depth-to-water area polygons for the Humboldt River Basin, Nevada as published in the Nevada Department of Conservation and Natural Resources Water Resources Bulletin 32 titled "Hydrologic reconnaissance of the Humboldt River basin, Nevada", 1966.

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.
