Groundwater-Level Trends in Snake Valley and Adjacent Basins, Utah and Nevada (RI-285)

by Hugh A. Hurlow, Rebecca Molinari, Paul C. Inkenbrandt, and J. Lucy Jordan

The Utah Geological Survey conducted a regional groundwater-level campaign during 2020 in west-central Utah and in parts of east-central Nevada to document changes in groundwater levels from 2010 to 2020 and produce an updated potentiometric-surface map for Snake Valley and adjacent groundwater basins. This report presents the results conducted in 2020, designed to build on and contrast with a similar survey conducted by the U.S. Geological Survey in 2010. Investigations were done on the use of hydrographs of vertical hydraulic gradients in nested piezometers to illustrate changes in groundwater dynamics, and application of breakpoint analysis combined with Mann-Kendall analysis to identify key times of change.
