These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data set contains the main stem of the Humboldt River as defined by Humboldt Project personnel of the U.S. Geological Survey Nevada District, 2001. The data set was digitized on screen using digital orthophoto quadrangles from 1994.
The USGS and Newmont Mining Corp. surveyed 51 cross sections to determine hydraulic characteristics throughout 12 model reaches. The accuracy of the surveyed cross sections is believed to be +/- 0.5 ft. Field surveys included measuring the channel cross section up to the approximate altitude of the highest flood and includes auxiliary channels. Surveyed cross sections generally were at representative locations about every 3 miles along the Humboldt River channel. In areas where long overbank sections occurred, supplemental altitudes were determined from topographic maps in order to extend surveyed parts of cross sections so that each section represented the full width of the floodplain. In this dataset there is...
This digital vector dataset represents the Northern Nevada Rift as published in an article describing the relationship of epithermal gold deposits to large-scale fractures in Northern Nevada (Ponce and Glen, 2002). The data are represented on figures 1-5 in the source publication and were later provided in an Esri shapefile via written communication from D.A. Ponce in 2017. An attribute field was added to distinguish the northern Nevada rift-east, northern Nevada rift-central, and northern Nevada rift-west.
This data release contains depth-to-groundwater, water withdrawal, and analyses associated with multiple aquifer tests conducted between March 2017 and April 2018 in Lovelock, NV. Seven slug tests, one single-well pumping test, and two multi-well pumping tests were conducted to evaluate properties of the Lahontan clays and silts, fluvial deposits, and coarser, water-bearing deposits of the Younger Alluvium. Data and analyses are presented in folders named according to type of test and aquifer analyzed, as described in the larger work.
