Science in the Colorado River Basin
The Colorado River is one of the longest rivers in the Western United States. It begins in the Rocky Mountains of Colorado and flows southwestward until it reaches Mexico where it becomes a small stream or dry riverbed. The Colorado River forms the border between southeastern Nevada and northwestern Arizona. In Nevada, Hoover Dam and Davis Dam control the flow of the river and create two...
Measurements of Stream Discharge and Analysis of Surface Water/Groundwater Interactions in Las Vegas Wash, Las Vegas, NV
The Black Mountain Industrial (BMI) complex, in Henderson, Nevada, has been the site of industrial chemical production since 1942. Perchlorate contaminants, from activities at BMI, have moved through the groundwater system and have been discovered in the Las Vegas Wash, prompting water resource investigations and groundwater treatment by the Nevada Division of Environmental Protection (NDEP). The...
Amargosa Integrated Monitoring Network
The National Park Service, Nye County, U.S. Fish and Wildlife Service, and USGS Nevada Water Science Center (NVWSC) have established a water-level and spring discharge monitoring network in the southern Amargosa Desert to identify long-term trends and monitor potential impacts of activities on groundwater resources. The Amargosa Integrated Monitoring Network (AIMN) continues the long-term...
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 and...
Trace of the lower Las Vegas Wash study area, 2017
This vector line dataset represents the lower Las Vegas Wash study area. Surface-water trace was digitized onscreen from Landsat8 and ESRI World Imagery. The trace is used in an accompanying surface-water study to evaluate discharge gains and losses at selected locations in the Lower Las Vegas Wash.
Drilling, Construction, Water Chemistry, Water Levels, and Regional Potentiometric Surface of the Upper Carbonate-Rock Aquifer in Clark County, Nevada
This USGS data release contains the regional potentiometric contours representing the regional potentiometric surface for Clark County, Nevada, 2009-2015. Contours represent the groundwater-level altitude with a 250-foot contour interval and were created from groundwater elevations from 58 wells and surface elevations from 5 springs.
Drilling, construction, water chemistry, water levels, and regional potentiometric surface of the upper carbonate-rock aquifer in Clark County, Nevada, 2009–2015
The U.S. Geological Survey (USGS) and the Bureau of Land Management (BLM) initiated a cooperative study through the Southern Nevada Public Land Management Act (Bureau of Land Management, 1998) to install six wells in the carbonate-rock and basin-fill aquifers of Clark County, Nevada, in areas of sparse groundwater data. This map uses water levels from these new wells, water levels from existing we
Discharge data collection and analysis and implications for surface-water/groundwater interactions in the lower Las Vegas Wash, Clark County, Nevada, 2016–18
The lower Las Vegas Wash represents the terminal surface drainage for the Las Vegas Valley in southern Nevada. In 1997, high concentrations of perchlorate were found in seeps contributing to discharge in this area and traced to an industrial byproduct from manufacturing operations in the mid-1900s at the nearby Basic Magnesium, Incorporated, plant. The discovery prompted a water-resources investig
Moving in the Anthropocene: Global reductions in terrestrial mammalian movements
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of t
Hydrogeology and sources of water to select springs in Black Canyon, south of Hoover Dam, Lake Mead National Recreation Area, Nevada and Arizona
Springs in Black Canyon of the Colorado River, directly south of Hoover Dam in the Lake Mead National Recreation Area, Nevada and Arizona, are important hydrologic features that support a unique riparian ecosystem including habitat for endangered species. Rapid population growth in areas near and surrounding Black Canyon has caused concern among resource managers that such growth could affect the
Synoptic Discharge, Water-Property, and pH Measurements for Muddy River Springs Area and Muddy River, Nevada, February 7, 2001
On February 7, 2001, synoptic discharge measurements at selected sites along the Muddy River in Nevada, indicated three trends in discharge resulting from contributions of spring discharge, influences of diversionary flow, and contributions from shallow ground water. Effects from diversionary and tributary flow were local in nature and resulted in a net gain of 2.6 cubic feet per second throughout
