This USGS data release represents the evapotranspiration units and potential areas of groundwater discharge geospatial data from the following publication: Plume, R.W., and Smith, J.L., 2013, Properties of basin-fill deposits, a 1971–2000 water budget, and surface-water-groundwater interactions in the upper Humboldt River basin, northeastern Nevada: U.S. Geological Survey Scientific Investigations Report 2013-5077, 38 p., http://pubs.usgs.gov/sir/2013/5077/. The data set consists of 2 separate items: 1. evapotranspiration units 2. potential areas of groundwater discharge

Over the past 15 years Douglas County, NV has removed production wells in northern Carson Valley from use due to relatively high arsenic concentrations (Carl Ruschmeyer, January 2013, Douglas County Public Works Director, verbal communication). To maintain the supply of water to the public, the town of Minden has been providing water to Douglas County and Carson City. Due to the projected increases in municipal demand, water resource managers are concerned that increasing pumping rates from wells in Minden may change groundwater chemistry and degrade the resource by potentially drawing in arsenic enriched water. Naturally occurring arsenic is one of the most common contaminants in groundwater in the western United...

The U.S. Geological Survey (USGS), in cooperation with the Arkansas Natural Resources Commission, Arkansas Geological Survey, and the Union County Water Conservation Board, has monitored water levels as a part of an ongoing effort to provide information for management of the Sparta-Memphis aquifer. The USGS has produced reports, at various intervals, to describe groundwater conditions in the Sparta-Memphis aquifer. These datasets provide the locations of and groundwater-level altitudes from 306 wells that were used to construct a potentiometric contour surface of the Sparta-Memphis aquifer. Measurements were made from January through May 2013 and represent synoptic conditions. All wells were cased completely in...

This USGS data release represents the 1:500,000-scale geospatial data for the following publication: Eakin, T.E., and Lamke, R.D., 1966, Hydrologic reconnaissance of the Humboldt River basin, Nevada: Nevada Department of Conservation and Natural Resources, Water Resources Bulletin 32, 107 p. The data set consists of 3 separate items: 1. Depth-to-water area polygons 2. Isopleths showing mean annual runoff, 1912-1963 3. Water-level altitude contours

This USGS data release consists of two geospatial datasets. One dataset contains contours representing water levels based on depth-to-groundwater measurements made at 98 wells in July of 2012 in the Lahontan Valley near Fallon, NV. The second dataset contains contours representing 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. These data support USGS Scientific Investigations Report 2016-5045 - Groundwater-Level Change and Evaluation of Simulated Water Levels for Irrigated Areas in Lahontan Valley, Churchill County, West-Central Nevada, 1992‒2012
