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.

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

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

Science in the Truckee River Basin

The Truckee River flows for 120 miles from the outlet of Lake Tahoe in California, into Nevada, through the city of Reno, until it terminates at Pyramid Lake and is the only source of surface-water outflow from Lake Tahoe. The majority of the streamflow in the Truckee River comes from the Sierra Nevada snowpack. Contributions to the river in Nevada are small due to the Sierra Nevada’s “rain shadow...

Evaluation of water-level decline and aquifer properties in the Virginia City Highlands and Highland Ranches Volcanic Rock aquifer system, Storey County, Nevada

The Virginia City Highlands and Highland Ranches (VC Highlands) are a rural residential housing area established along the ridge of the Virginia Range in Storey County, Nevada. Approximately 1,400 residents exclusively rely on domestic wells for water supply and domestic well depths range from 75 to 1,175 ft below land surface. NVWSC monitors water levels annually in two domestic wells in the VC...

Science in the Humboldt River Basin

The Humboldt River is in north-central Nevada. The river is about 330 miles long and provides water for mostly agricultural purposes. One of the largest industries in Nevada is gold mining and the majority of those mines are in the Humboldt River Basin on the Carlin Trend. Gold mines in Nevada produce 72 percent of all the gold in the U.S. and are the 5th largest in the world. In 2022, Nevada...

Arsenic in Nevada Groundwater

From 2007 to 2021, the U.S. Geological Survey (USGS) collaborated with the Nevada Bureau of Mines and Geology on evaluating the forms of arsenic in Nevada groundwater resources. A total of 190 groundwater samples were collected from wells and springs throughout Nevada. Concentrations of arsenic ranged from <1.6 to 2,408 micrograms per liter (µg/L); in most cases, arsenate was the dominant species...
