A three-dimensional, groundwater-flow model (MODFLOW-2005) was developed to estimate the hydraulic properties (e.g., transmissivity, hydraulic conductivity, specific yield, and specific storage) of volcanic rocks in Pahute Mesa, Nye County, Nevada. The model was calibrated using parameter estimation (PEST) by fitting estimated drawdowns to simulated drawdowns from 16 multiple-well aquifer tests. Water-level models were used to estimate drawdowns from continuous water-level data collected during multiple-well aquifer testing. This USGS data release contains all of the input and output files for the simulations described in the associated model documentation report (http://doi.org/10.3133/sir20165151). This data release...
This data release consists of four directories: GroundwaterWithdrawals, Precipitation, WaterLevelDatabase, and WLMs. The GroundwaterWithdrawals directory contains a Microsoft Excel workbook with groundwater withdrawal data from 1996-2015 for water-supply wells in Beatty and Bullfrog Hills, Nye County, Nevada. The Precipitation directory contains four Microsoft Excel workbooks with data from precipitation stations and analyses used to construct long-term precipitation index records. The WaterLevelDatabase directory contains a Microsoft Excel workbook with hydrographs and well information for the 79 wells analyzed in the larger work. The WLMs directory contains 11 water-level models that were used to determine hydrologic...
