Nevada Water Science Center
The Nevada Water Science Center (NVWSC) is committed to providing reliable, unbiased scientific information about Nevada's water resources to the public, cooperators, and stakeholders. To provide this information, we operate widespread data collection networks as well as conduct water-science research covering a wide range of scientific issues throughout Nevada and adjacent states.

Statistical analysis of Lake Tahoe secchi depth data
Secchi depth measurements in Lake Tahoe have been collected at a Long-Term Profile (LTP) monitoring site since 1968. Periodic updates in Secchi trend analysis are needed to understand changes in the long-term record, changes in seasonal pattern, and to provide insight into the progress of restoration efforts in improving lake clarity. As such, this analysis is intended to evaluate the long-term an
Assessment of water levels, nitrate, and arsenic in the Carson Valley Alluvial Aquifer and the development of a data visualization tool for the Carson River Basin, Nevada
Residents of Carson Valley, Douglas County, Nevada, rely on the basin-fill alluvial aquifer underlying the valley for drinking water. Since the 1980s, groundwater levels and water-quality data have been collected to monitor the status of the aquifer system and to assist in planning efforts to address current (2024) and future demand. The U.S. Geological Survey (USGS), in cooperation with Douglas C
A conceptual framework to assess post-wildfire water quality: State of the science and knowledge gaps
Wildfire substantially alters aquatic ecosystems by inducing moderate to catastrophic physical and chemical changes. However, the relations of environmental and watershed variables that drive those effects are complex. We present a Driver-Factor-Stressor-Effect (DFSE) conceptual framework to assess the current state of the science related to post-wildfire water-quality. We reviewed 64 peer-reviewe

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...
Actionable Science
The Colorado River Basin Pilot Project is exploring new approaches for the USGS to answer complex earth systems questions identified in partnership with stakeholders, which cannot be answered through a single discipline approach. Science coproduction is a method where scientists, managers, policy makers, and other stakeholders first identify specific decisions to be informed by science, and then...

Integrated Science Approach
The USGS has a long history of delivering science and tools to help decision-makers manage and mitigate effects of drought. The timing is critical for the USGS to consolidate its diverse expertise into a single landscape-scale effort to rapidly provide integrated transdisciplinary, targeted data, tools, and models required by decision makers in the Basin. This initiative unifies USGS expertise...
