Evaporation from Lake Mead and Lake Mohave, Lower Colorado River Basin, Nevada and Arizona

The Bureau of Reclamation currently operates a model that projects future Colorado River reservoir volumes and potential dam operations based on current and forecasted hydrologic conditions, and operational policies and guidelines (the 24-Month Study). Each month a water budget is developed and Colorado River reservoir...

Budgets and Chemical Characterization of Groundwater for the Diamond Valley Flow System, Central Nevada

The Diamond Valley flow system (DVFS) consists of six basins or hydrographic areas (HAs) in central Nevada: southern and northern Monitor Valleys, Antelope Valley, Kobeh Valley, Stevens Basin, and Diamond Valley. The six basins are, in part, hydrologically connected by ephemeral streams, by groundwater flow in shallow basin-fill aquifers, and, possibly, by subsurface flow in deeper carbonate-...

Groundwater Discharge by Evapotranspiration, Flow of Water in Unsaturated Soil, and Stable Isotope Water Sourcing in Areas of Sparse Vegetation, Amargosa Desert, Nye County, Nevada

The USGS conducted a study to evaluate the potential for groundwater discharge from sparsely vegetated areas in the Amargosa Desert. The study objectives were to: (1) compute groundwater discharge based on evapotranspiration and precipitation measurements at instrumented sites, and (2) improve understanding of hydrologic-continuum processes controlling groundwater discharge through analysis of...

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,...

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...

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...
