Nevada Water Science Center

Water Availability and Use

Water for agriculture and livestock is the largest use of both surface- and groundwater in Nevada. As the Nation’s most arid state, management of Nevada’s water resources is critical and complex. NVWSC is focused on developing new and innovative science to evaluate and answer the complex questions regarding Nevada’s water availabilty and use.

Quantifying watershed controls on fine sediment particles and nutrient loading to Lake Tahoe using data mining and machine learning

Since the late 1980’s, the USGS has collected discharge, sediment, and water quality data at seven major drainages under the Lake Tahoe Interagency Monitoring Program (LTIMP). Recently, continuous, real-time measurements of turbidity were added to the LTIMP. These data can be combined with in situ, model simulations, and remotely-sensed datasets available from the USGS, National Aeronautics...

Development of landscape variables to inform models of meadow vulnerabilities and adaptation under changing climate

The USGS Nevada Water Science Center is providing technical assistance for the collection of landscape variables hypothesized to influence meadow responses to climate and restoration activities. These data will be used in a decision support framework developed by the U.S. Forest Service (USFS) and Desert Research Institute (DRI).

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...

Quantifying Seepage Losses on the Truckee Canal, Derby Dam to Lahontan Reservoir

Seepage losses from the Truckee Canal poses major challenges to water managers. Seepage losses result in inefficiencies in water delivery and cause more water than is needed by farmers to be diverted from the Truckee River to meet required demands. Increased diversions from the Truckee River result in less water flowing through the lower Truckee River system and into Pyramid Lake, a terminal...

Hydrology of the Walker River Basin

Walker Lake is one of the few perennial, natural terminal lakes in the Great Basin.  The ecosystems and recreational uses of Walker Lake and other terminal lakes in the Great Basin have become at-risk due to consumptive water use.

Aquifer Tests in Nevada

Many aquifer tests have been conducted by the U.S. Geological Survey to estimate hydraulic properties of aquifers in Nevada and adjacent states. Transmissivity is the principal hydraulic property that has been estimated from the aquifer tests in Nevada because these values directly affect estimates of ground-water flow.

Evapotranspiration Studies in Nevada

Evapotranspiration (ET) is the process that transfers water from land surface to the atmosphere as evaporation (or sublimation when below freezing) from open water, soil, and plant canopies and as transpiration by plants. ET is measured by scientists for many different reasons. Hydrologists from the Nevada Water Scientist Center (NVWSC) typically measure ET to help quantify water budgets....

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...

Science in the Walker River Basin

The Walker River begins in the Sierra Nevada as the East Walker River and the West Walker River. In Mason Valley, just south of Yerington, Nev., the rivers converge to create the the Walker River. The Walker River terminates in Walker Lake.

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...

Water Resources of the Upper Humboldt River Basin

Elko County officials and citizens are concerned about growing demand for groundwater within the county and demands for groundwater that are occurring elsewhere in the state. Because the Humboldt River is fully appropriated, any additional water needed to support growth in the upper Humboldt River Basin will have to come from groundwater. County and state water-resource managers need...

Science in the Carson River Basin

The Carson River begins in the Sierra Nevada as the East Fork and West Fork of the Carson River. These two forks come together in the Carson Valley, not far from Carson City, Nev. The river then flows through the Carson River Basin until its terminus at the Carson Sink. The Carson River is a popular recreation spot with rafters, hikers, and fishermen.
