An existing three-dimensional groundwater flow model of northern Utah County (https://doi.org/10.3133/sir20095049), was updated for use with the Groundwater Management Process(GWM) for MODFLOW-2005, to evaluate the optimal managed aquifer recharge scenarios with the objective of maintaining acceptable reductions in simulated discharge at 12 groundwater discharge areas along Utah Lake. Groundwater is a primary source of drinking water in northern Utah County. By 2066, the amount of groundwater withdrawn is estimated to be roughly 65 percent of annual average recharge. To prepare for anticipated future increases in groundwater withdrawals, local cities have identified 16 locations as feasible for managed aquifer recharge....
A previously developed three-dimensional steady-state numerical groundwater-flow model was modified to transient conditions with respect to well withdrawals, and used to simulate drawdown and capture of natural discharge from existing and proposed groundwater withdrawals in Snake Valley and adjacent areas in western Utah and eastern Nevada. The original steady-state model simulates and was calibrated to 2009 conditions and was used as the first stress period in this transient model. Six transient stress periods, spanning 2010-2114, were added to the model to assess timing of the potential withdrawal effects. A seventh steady-state stress period was also added to determine the ultimate long-term effects of the well...
A new version of previously published steady-state numerical groundwater flow models of the Great Basin carbonate and alluvial aquifer system (GBCAAS), and was developed in conjunction with U.S. Geological Survey (USGS) studies in Parowan, Pine, and Wah Wah Valleys, Utah. This version of the model is considered to be GBCAAS v. 3.0 and supersedes previous versions. This model added 15 transient calibration stress periods and 14 projection stress periods, aquifer storage properties, historical withdrawals in Parowan Valley, and observations of water-level changes in Parowan Valley to the previous steady-state versions. Recharge in Parowan Valley and withdrawal from wells in Parowan Valley and two nearby wells in Cedar...
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 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...
