MODFLOW-2005 and PEST Models used to simulate the 2016 carbonate-rock aquifer test and characterize hydraulic properties of carbonate-rock and basin-fill aquifers near Long Canyon, Goshute Valley, northeastern Nevada

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).
