MODFLOW-2005 files for numerical model simulations of potential changes in water levels and capture of natural discharge from groundwater withdrawals in Snake Valley and adjacent areas, Utah and Nevada

Metadata Updated: September 17, 2025

A previously developed numerical groundwater flow model of the eastern Great Basin was used to investigate where potential drawdown and capture of natural discharge is likely to result from potential groundwater withdrawals from existing and applied for groundwater rights in Snake Valley, Utah and Nevada. SIR 2014-5213 (https://doi.org/10.3133/sir20145213), SIR 2017–5011 (https://doi.org/10.3133/sir20175011), and SIR 2017-5072 (https://doi.org/10.3133/sir20175072) document the construction and calibration of the previous versions of this model. The eastern Great Basin model consists of a parent model and a child model. The parent model covers the focus study area and was used for the simulations presented in this data release, and documented in U.S. Geological Survey Open-File report 2019-1083 (https://doi.org/10.3133/ofr20191083). To investigate the potential effects of existing groundwater-right withdrawals and applications in Snake Valley, eleven withdrawal scenarios (scenarios A–G) were simulated. All scenarios were run as steady state to determine the ultimate long-term effects of the simulated withdrawals. Because only the parent model was used, the parent model was converted to run with MODFLOW-2005. Modifications were made to several of the the MODFLOW and ZONEBUDGET input packages and files including the MODFLOW-2005 Name File, the MODFLOW-2005 Hydrogeologic-Unit Flow Package, the MODFLOW-2005 Well Package, the MODLFOW-2005 Head Observation Package, the ZONEBUDGET Zone File, and the ZONEBUDGET Main Input File. 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/ofr20191083).
