Groundwater Modeling for the Dry Lake Valley North SEZ

The purpose of the Dry Lake Valley North model is to assess potential impacts associated with groundwater withdrawals to support solar energy development in the vicinity of the Dry Lake Valley North SEZ. This SEZ is located in Dry Lake Valley (Hydrologic Area 181).

The Dry Lake Valley North SEZ model is an update of the one-dimensional modeling performed as part of the Programmatic Environmental Impact Statement. The model is based on the Theis-Jacob method, and it relies on a thorough review of available hydrogeologic data and an assessment of the sensitivity of parameter values. Twenty years of high-, medium-, and low-demand groundwater pumping at the SEZ were modeled, producing estimates of the additional groundwater drawdown due to full build-out of the SEZ. The medium-demand case was selected for sensitivity analyses.
