Water Data
Water Data
Nevada is the most arid state in the Nation, receiving as little as 3 inches of annual precipitation in some parts of the state, while total statewide annual precipitation measures less than 10 inches. Consequently, Nevada only has large streams but no large rivers and only a few large lakes. Water resources throughout the State are limited making data about streams and lakes extremely important.

Science in the Carson River Basin
The Carson River is an important water resource for residents, agriculture, and wildlife. At the headwaters, precipitation assnow and rain can produce runoff that is unregulated until it reaches Lahontan reservoir. Water flowing in the mainstem may be diverted in Carson Valley for agriculture and for municipal water uses. At Lahontan Reservoir, water imported from the Truckee River Basin is used...
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...
Evaluation of Black Rock Desert National Conservation Area
Minimal hydrologic data are available for the Black Rock National Conservation Area (BRNCA). USGS scientists collected baseline spring flow, groundwater level, and precipitation data to support concurrent ecological studies of perennial springs in the BRNCA by the Desert Research Institute. The collection of baseline hydrologic data is the initial step for determining how ecosystems in the BRNCA...
Water for the Seasons
Water for the Seasons (WftS) is a four year study funded by the National Science Foundation and the U.S. Department of Agriculture. WtfS uses the Truckee-Carson River System (TCRS) as a pilot study to learn how to best link science with decision-making in snow-fed arid-land river systems. By working collaboratively with stakeholders, WftS aims to create a model for improving community climate...
Amargosa Integrated Monitoring Network
The National Park Service, Nye County, U.S. Fish and Wildlife Service, and USGS Nevada Water Science Center (NVWSC) have established a water-level and spring discharge monitoring network in the southern Amargosa Desert to identify long-term trends and monitor potential impacts of activities on groundwater resources. The Amargosa Integrated Monitoring Network (AIMN) continues the long-term...
Groundwater Discharge by Evapotranspiration from Areas of Spring-Fed Riparian Vegetation, Stump Spring and Hiko Springs, Nev.
Stump Spring has been designated as an Area of Critical Environmental Concern by the Bureau of Land Management (BLM), and Hiko Springs currently is in the designation process. Both springs flow intermittently in drainages where the depth to groundwater is shallow. The shallow groundwater flowing to and from the springs sustain scarce desert riparian habitats. BLM has recognized a need for accurate...
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...
Water Quality of Springs in the Spring Mountains
The USGS Nevada Water Science Center, in cooperation with the Bureau of Land Management, is sampling and analyzing water from Grapevine, Kiup, and Rainbow Springs to determine the source of water to these springs. These Springs, located in the Spring Mountains in southern Nevada, provide habitat for endangered spring snail species including the southeast Nevada Pyrg (Pyrgulopsis turbatrix) and 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 flow...
Occurrence and Mobility of Arsenic in Groundwater Used for Public Supply in Southern Carson Valley, Douglas County, Nevada
Over the past 15 years, Douglas County, Nev., has removed production wells in northern Carson Valley from use due to relatively high arsenic concentrations. To maintain the supply of water to the public, the town of Minden has been providing water to Douglas County and Carson City. Due to the projected increases in municipal demand, water resource managers are concerned that increasing pumping...
