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).

Data for the 2009 report Hydrologic Setting and Conceptual Hydrologic Model of the Walker River Basin, West-Central Nevada
This U.S. Geological Survey data release contains data for Smith and Mason Valleys, California and Nevada, from the 2009 publication: Lopes, T.J.,and Allander, K.K., 2009, Hydrologic Setting and Conceptual Hydrologic Model of the Walker River Basin, West-Central Nevada: U.S. Geological Survey Scientific Investigations Report 2009–5155, https://doi.org/10.3133/sir20095155. Data include (1) 1:24,000-scale hydrographic areas, (2) selected well sites used to develop autumn 2006 groundwater-level contours, and (3) autumn 2006 groundwater-level contours. 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...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
