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 publication provides digital flight line data for a high-resolution magnetic and radiometric survey over an area of southeast Illinois, western Kentucky, and southern Indiana. The survey includes airborne geophysical data collected as part of the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) effort (Day, 2019). Earth MRI is a cooperative effort between the USGS, the Association of American State Geologists, and other Federal, State, and private sector organizations to improve our knowledge of the geologic framework of the United States. Data for this survey were collected by EON Geosciences under contract with the USGS using a fixed wing aircraft with a magnetometer mounted in...

These contours represent static groundwater levels based on depth-to-water measurements in Smith Valley and Mason Valley, Nevada, for fall 2006. Groundwater-level contours were first published by Lopes and Allander (2009) and subsequently published electronically by Medina and others (2022). Since the time of the dataset's original publication, the position and land-surface altitude at 23 monitoring wells in Smith Valley used to develop the original 2006 groundwater-level contours have been updated. As such, 10 contours in Smith Valley were revised using the updated monitoring well locations and land-surface altitudes while maintaining, to the extent possible, the original interpretation made by Lopes and Allander...

This dataset consists of points representing selected monitoring well locations and median groundwater-level altitudes for the water year period 1991-1995 that were used to develop groundwater-level contours in Smith and Mason Valleys, Nevada. Groundwater-level measurements were collected by the USGS and the Nevada Division of Water Resources (NDWR).

These contours represent static groundwater levels based on depth-to-water measurements made at 96 monitoring wells during water years 1991-1995 in Smith Valley and Mason Valley, Nevada. For each monitoring well, the median groundwater-level altitude during the five-year period (1991-1995) 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 represents the areal extent used to estimate groundwater-level and groundwater storage-volume change in Smith Valley and Mason Valley, Nevada. Each groundwater-level dataset used in this study (1970, 1995, 2006, 2020) contained a unique areal extent because the monitoring wells used to create each dataset was different and as a result, the extent of groundwater-level contours differed. Defining a common extent among all datasets was needed to evaluate water-level change and groundwater storage-volume change using a consistent approach.

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...

These contours represent static groundwater levels based on depth-to-water measurements in Smith Valley and Mason Valley, Nevada. Groundwater-level contours for Smith Valley were first published by Rush and Schroer (1976) and subsequently published electronically by Welborn and Medina (2022). The Smith Valley groundwater-level contours represent conditions in the spring of 1972. Groundwater-level contours for Mason Valley were first published by Huxel and Harris (1969) and subsequently published electronically by Lopes and others (2006). The Mason Valley groundwater-level contours represent conditions during 1965-1966. The original groundwater-level contours from Smith Valley and Mason Valley (Huxel and Harris,...
