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...

Evaluation of Streamflow Depletion Related to Groundwater Withdrawal, Humboldt River Basin

The Humboldt River Basin (HRB) is the only major river basin that is entirely within the State of Nevada. Precipitation supplies all the water that enters the basin; consequently, the variability in climate has significant impacts on the hydrology of the area.

Nevada StreamStats

The USGS Nevada Water Science Center (NVWSC), in partnership with the Bureau of Land Management (BLM) and the Nevada Division of Water Resources (NDWR), is updating streamflow statistics for Nevada. Additionally, the project includes launching StreamStats, a web-based Geographic Information Systems (GIS) tool that provides streamflow statistics and information about drainage basins. Work on this...

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...

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...

Evaluation of Groundwater Flow in the Middle Carson River Basin, Eagle, Dayton, and Churchill Valleys, Nevada

Demand for water resources in the Carson River basin is increasing due to steady population growth and the resulting development and changes in land and water use throughout the middle part of the basin. Agricultural land is being urbanized while land not previously irrigated may be converted for agricultural use.

Lake Tahoe Nearshore Periphyton Study

Periphyton, a type of algae, is growing on bottom sediment and rocks along nearshore areas of Lake Tahoe. Periphyton is seen as a nuisance and negatively impacts the recreational value of the lake. Periphyton biomass (PB) data collected along the nearshore of Lake Tahoe exhibit increasing trends over the last decade. However, the mechanisms that have caused these changes are not well understood.

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 and...

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).
