This dataset presents data and analysis from a carbonate-rock aquifer test, conducted near Long Canyon, Nevada in 2016 by Newmont Mining Corporation. Data collected during the test include tabular pumping, subsurface loss from spring supplementation and aquifer-test discharge (ditch discharge), water-levels, and weather data. Water-level, pumping, and spring data were collected and furnished by Newmont Mining Corporation. The furnished data were input into water-level models to estimate monitoring-site drawdown or rise. Water-level models were created using SeriesSEE (Halford and others, 2012), an Excel Add-in. Water-level model input files, archived water-level models, the Excel Add-in, hydrographs, and estimates of monitoring-site drawdown or rise are presented.

This dataset presents tabular data and Excel workbooks used to analyze single-well aquifer tests in pumping wells and slug tests in monitoring wells near Long Canyon. The data also include pdf outputs from the analysis program, Aqtesolv (Duffield, 2007). The data are presented in two zipped files, (1) single-well aquifer tests in pumping wells and (2) slug tests in monitoring wells. The slug-test data were supplied by Newmont Mining Corporation and collected by Golder and Associates in 2011.

This data set represents the extent of the Basin and Range carbonate-rock aquifers in the states of Idaho, Utah, Arizona, Nevada, and California.

This data set represents the extent of the Basin and Range carbonate-rock aquifers in the states of Idaho, Utah, Arizona, Nevada, and California.

This dataset was created in support of a study focusing on groundwater resources in the Great Basin carbonate and alluvial aquifer system (GBCAAS). The GBCAAS is a complex aquifer system comprised of both unconsolidated and bedrock formations covering an area of approximately 110,000 square miles. The aquifer system is situated in the eastern portion of the Great Basin Province of the western United States. The eastern Great Basin is experiencing rapid population growth and has some of the highest per capita water use in the Nation. These factors, combined with the arid setting, have levied intensive demand upon current groundwater resources and, thus, predictions of future shortages. Because of the large regional extent of the aquifer system, rapid growth in the region, and the reliance upon groundwater for urban populations, agriculture, and native habitats, the GBCAAS was selected by the U.S. Geological Survey (USGS) Water Resources program as part of the National Water Census Initiative to evaluate the Nation's groundwater availability. The complex stratigraphic and structural framework of the GBCAAS region controls groundwater flow throughout the region. A three-dimensional (3D) hydrogeologic framework was constructed to represent the hydrogeologic units and major structures in the region to aid in the development of both the conceptual and numerical groundwater-flow models of the study area. The 3D hydrogeologic framework was constructed by extracting and combining information from digital elevation models, geologic maps, borehole lithologic logs, geologic cross sections, and digital geophysical models. This dataset is composed of nine raster layers: 1. ubfau_top - Altitude of the top of the upper basin-fill aquifer unit in meters above North American vertical datum of 1988. 2. lbfau_top - Altitude of the top of the lower basin-fill aquifer unit in meters above North American vertical datum of 1988. 3. vu_top - Altitude of the top of the volcanic unit in meters above North American vertical datum of 1988. 4. ucau_top - Altitude of the top of the upper carbonate aquifer unit in meters above North American vertical datum of 1988. 5. uscu_top - Altitude of the top of the upper siliciclastic confining unit in meters above North American vertical datum of 1988. 6. tlcau_top - Altitude of the top of the thrusted lower carbonate aquifer unit in meters above North American vertical datum of 1988. 7. lcau_top - Altitude of the top of the lower carbonate aquifer unit in meters above North American vertical datum of 1988. 8. tnccu_top - Altitude of the top of the thrusted noncarbonate confining unit in meters above North American vertical datum of 1988. 9. nccu_top - Altitude of the top of the noncarbonate confining unit in meters above North American vertical datum of 1988.

A three-dimension groundwater-flow model (MODFLOW-2005) was developed to improve understanding of groundwater flow and pumping effects near the Long Canyon Mine in Goshute Valley, northeastern Nevada. Bulk hydraulic properties of carbonate rocks and basin-fill aquifers were characterized by simultaneously interpreting steady-state flow during predevelopment conditions and changes in groundwater levels and spring flows from the 2016 multiple-well aquifer test with an integrated groundwater-flow model. This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report (https://doi.org/10.3133/sir20215021).
