     "text": "USGS has revised the regional-scale Death Valley regional groundwater flow system (DVRFS) numerical model with new data and interpretations since the original numerical flow model was published in 2004 and republished in 2010. Since the original publication of the DVRFS flow model, additional data have been collected and interpretations have been made. Cooperators such as the Bureau of Land Management, National Park Service, U.S. Fish and Wildlife Service, the Department of Energy, and Nye County, Nevada, recognized a need to update the existing regional numerical flow model to maintain its viability as a groundwater management tool for regional stakeholders."

     "text": "The Death Valley regional groundwater flow system (DVRFS) is located in the southern Great Basin physiographic province in southern Nevada and eastern California.  Because of the arid nature of this region and its increased urbanization, there are many varying and competing interests involving the regional ground-water resources. Federal land-management agencies and Nye County are concerned that increased ground-water pumping from existing and new wells in southern Amargosa and Pahrump Valleys could impact nearby water-dependent ecosystems by reducing the amount of natural groundwater discharge and decreasing shallow water tables. Groundwater discharges at Ash Meadows National Wildlife Refuge, at numerous springs and seeps, and along parts of the Amargosa River. Additionally, groundwater is intersected at Devils Hole, a fissure in a regional carbonate-rock aquifer. These areas support habitat for numerous species of plants and animals, including several federally-listed threatened and endangered species. To evaluate potential impacts from pumping to water levels and discharge within these areas of concern, USGS is"
