  • MODFLOW-NWT groundwater model used for simulating potential future pumping scenarios and forecasting associated groundwater-level changes in the Truxton aquifer on the Hualapai Reservation and adjacent areas, Mohave County, Arizona

    Metadata Updated: November 12, 2020

    A three-dimensional, numerical groundwater flow model of the Hualapai Plateau and Truxton Basin was developed to assist water-resource managers in understanding the potential effects of projected groundwater withdrawals on groundwater levels and storage in the basin. The Truxton Basin Hydrologic Model (TBHM) was developed using previously published data, as well as, new geophysical data collected as part of this investigation (Ball, 2020; Kennedy, 2020). TBHM is a transient model that simulates the hydrologic system between the years 1976–2140, including three hypothetical groundwater withdrawal scenarios between 2020–2140. The predevelopment (before 1976) groundwater system is simulated using a steady-state model. The TBHM study area encompasses 1,200 square miles (mi2), including the Truxton basin (approximately 75 mi2) and much of the surrounding Hualapai Plateau. Potential future pumping scenarios are simulated in Truxton Basin at the existing Truxton well field and at a hypothetical new pumping location in the northern portion of the basin. 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/sir20205017E).
