Floods in Nevada
For more than 100 years, the USGS has played a critical role in reducing flood losses by operating a nationwide streamgage network that monitors the water level and flow of the Nation's rivers and streams. Through satellite and computer technology, streamgages transmit real-time information, which the National Weather Service (NWS) uses to issue flood warnings.
Drought in Nevada
Ongoing drought, in Nevada and across the West, will require scientists to develop new ideas and techniques for measuring, monitoring, modeling, and managing water resources. NVWSC has the capabilities to meet these challenges with our extensive scientific expertise in data collection, modeling, and research. We also are creating new ways to provide data to the public and stakeholders through...
Potential Effects of Changing Climate Patterns on Subalpine Lakes in Great Basin National Park
Great Basin National Park (GRBA), in White Pine County, Nev., has six small subalpine lakes. These lakes are a priority resource for park managers due to their pristine condition and high visitation. The only trout species native to these lakes is the Bonneville cutthroat trout (BCT). In the late 1990s, GRBA began a BCT reintroduction program. The success of this program was one of the major...
Delineation of Flood-Inundation Areas in Grapevine Canyon near Scotty’s Castle, Death Valley National Park, California
On October 18, 2015 an intense, nearly stationary, thunderstorm triggered flooding in Grapevine Canyon. Grapevine Canyon Road, power and water infrastructure, and several buildings at Scotty’s Castle were damaged by the flood water, necessitating closure of the area to the public. In response to the flood event, the National Park Service requested the USGS Nevada Water Science Center perform a...
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...
