The purpose of the project was to determine the magnitude and extent of groundwater drawdown and stream depletion occurring due to high-capacity irrigation pumping from aquifers, and to evaluate possible impacts to sloughs and the Beaverhead River from future groundwater development.
Groundwater/surface-water interactions and pumping effects on water resources were examined through a detailed hydrogeologic investigation of the study area, which included field studies, analysis of data, and numerical modeling.
This GWIP study characterizes the hydrogeology and examines how the groundwater and surface-water systems respond to pumping through the following tasks:
