Nevada Water Science Center

Hydrologic Research

The NVWSC scientists are developing state-of-the-art methods for water quantity and quality assessments, predictive hydrologic models that are key to evaluating future responses of the water cycle to climate change, water resource assessments instrumental to policy makers for clearly weighing the competing energy alternatives and evaluating the environmental cost for energy development, and water-quality monitoring to detect emerging and other drinking-water contaminants that pose a risk to public health.

Evaluation of Groundwater Flow in the Southern Part of the Amargosa Desert, Nevada and California

Since the original publication of the Death Valley regional groundwater flow system (DVRFS) numerical model in 2004, more information on the regional groundwater flow system in the form of new data and interpretations has been compiled. 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,...

Monitoring Hydrogeologic Conditions in the Regional Carbonate Aquifer, Clark County, Nevada

The USGS Nevada Water Science Center is evaluating and enhancing our current understanding of the hydrologic condition of the regional groundwater flow system in Clark County, Nevada. In order to achieve this objective, monitoring wells were installed in consolidated bedrock in six select regions throughout Clark County. Water-level, elevation, and borehole geophysical data were synthesized...

Water Quality of Springs in the Spring Mountains

The USGS Nevada Water Science Center, in cooperation with the Bureau of Land Management, is sampling and analyzing water from Grapevine, Kiup, and Rainbow Springs to determine the source of water to these springs. These Springs, located in the Spring Mountains in southern Nevada, provide habitat for endangered spring snail species including the southeast Nevada Pyrg (Pyrgulopsis turbatrix) and...

Hydraulic Characterization of Aquifers near Long Canyon, Nevada

USGS scientists are characterizing hydraulic connectivity and bulk hydraulic properties of carbonate-rock and basin-fill aquifers in the vicinity of and downgradient from the Long Canyon Mine Project area in Goshute Valley, Nev., to better understand groundwater-flow paths and evaluate pumping effects on the hydrologic system. The Long Canyon Mine Project requires groundwater pumping from the...

Effects of Groundwater Withdrawals, Tracy Segment

The USGS Nevada Water Science Center began an investigation in 2010 to quantify hydrologic effects of groundwater withdrawals on Truckee River streamflow in the Tracy Segment hydrographic area, Storey, Washoe and Lyon Counties, Nevada. Groundwater gradients have been monitored at sites near pumping wells and the river. Water-level fluctuations resulting from local pumping are interpreted with...

Nevada Flood Chronology

The lowest annual average precipitation and one of the fastest growing populations in the United States contribute to a tendency for both the general public and land-use planners to underestimate flood hazards in Nevada, despite historical evidence of frequent flooding.

Spring Valley-Snake Valley Aquifers

Supplementary water supplies are needed for a rapidly growing population in southern Nevada. Ground-water resources from basin-fill and consolidated rock aquifers in southern Spring and Snake valleys in eastern Nevada have been identified as a potential water-supply source. These aquifers provide water to springs, streams, wetlands, limestone caves, and other biologically sensitive areas on...

Delineation of Vegetation Using Satellite Imagery, Clark County

In 2006, USGS, in cooperation with the Bureau of Land Management (BLM), began a 4-year study of the Red Rock Canyon National Conservation Area (NCA) to produce a land-cover data set from DigitalGlobe’s QuickBird high-resolution (2.4-meter) satellite imagery and field vegetation data. In 2010, the study was extended to include the Clark County portion of Mormon Mesa, and Coyote Springs and...

Occurrence and Mobility of Arsenic in Groundwater Used for Public Supply in Southern Carson Valley, Douglas County, Nevada

Over the past 15 years, Douglas County, Nev., has removed production wells in northern Carson Valley from use due to relatively high arsenic concentrations.  To maintain the supply of water to the public, the town of Minden has been providing water to Douglas County and Carson City.  Due to the projected increases in municipal demand, water resource managers are concerned that increasing...

Evaluating Artificial Storage and Recovery Potential of Bedell Flat, Washoe County, Nevada

Truckee Meadows Water Authority (TMWA) is a public water purveyor in northwest Nevada with responsibility for providing water to approximately 385,000 people in the Reno/Sparks metropolitan area and suburban communities north of Reno. TMWA has a conjunctive use strategy, which includes aquifer storage and recovery (ASR), to both maintain the health of local aquifers and supplement limited...

Evaluation of the Migration of Palliative Chemicals Used for Dust Abatement, Clark County, Nevada

The USGS Nevada Water Science Center is collaborating with the Bureau of Land Management and PolyAnalyltik Laboratory in Ontario, Canada to evaluate the potential migration of butyl acrylate vinyl acetate (dust palliative) in soil and storm runoff from areas of application in southern Nevada. There is concern regarding the exposure of the desert tortoise and other wildlife to palliative...

Monitoring Sediment and Water Quality in Clear Creek

Clear Creek is a small alpine stream that begins near Lake Tahoe in the Sierra Nevada. The creek flows roughly parallel to U.S. Highway 50 and discharges to the Carson River near Carson City, Nevada. The Nevada Department of Transportation (NDOT) is concerned about how historical and ongoing development in the Clear Creek drainage basin has/is affecting Clear Creek and its sediment-transport...
