Consistent, historic, and up-to-date ground-water data, such as water levels collected at wells and springs, are available from the USGS National Water Information System as graphs, tables, or files to download.
A systematic presentation of climatic and hydrogeologic framework of the area, regional analysis of ground-water recharge, and an overview of 8 site-specific case studies.
Description of the hydrogeologic framework of Antelope Valley and Bedell Flat in west-central Nevada north of Reno-Sparks area. Gravimetric and seismic-refraction methods were used in the study. Report available in PDF format or HTML format.
Links to research projects that will improve the ability to detect, monitor, and predict the effects of invasive species, including exotic animals, on native ecosystems of the Pacific Southwest (California, Nevada, Utah, and Arizona).
Describes and provides several detiled examples of impacts of human-induced land subsidence resulting from the extraction of subsurface water, including aquifer-system compaction, drainage of organic soils, dissolution and collapse of susceptible rocks.
Estimates of change in major types of land use and land cover from 1973 to 2000 should help model potential future change as climate, population, public policy, and technology change.
Field data and satellite images allow us to make a calibrated model of percent vegetation cover, which we can use to inform scientific investigations and land management efforts.
Geospatial analysis of factors affecting communities that are adjacent to Federal lands, especially those lands subject to varying public interest and visitation.
Near-real-time maps of location, ground motion, and shaking intensity of earthquakes in California and Nevada for the past hour, past day, and past week and links to other earthquake information.
Examples of the use of Satellite Interferometric Synthetic Aperture Radar to measure and map changes on the Earth's surface as an aid to understanding how ground-water pumping, hydrocarbon production, or other human activities cause land subsidence.
