Monitoring the chloride (Cl) flux in the major rivers draining Yellowstone National Park (YNP) provides a holistic view of the thermal output from the underlying magma reservoir, and abrupt fluctuations in the Cl flux may signify changes in hydrothermal activity. The U.S. Geological Survey (USGS) and the National Park Service (NPS) have collaborated on Cl flux monitoring of the major rivers since the 1970s. In the past, researchers collected water samples from the major rivers in YNP, but funding restrictions, winter conditions, and the great distances between sites limited the number of samples collected annually. Beginning in 2010, specific conductance, which is relatively easy to measure and can be automated,...

The Shasta salamander (Hydromantes shastae) has been petitioned for listing under the Endangered Species Act. The greatest threat to the species is likely habitat loss that will be caused by the increase in elevation of Shasta Lake that will occur with proposed increases in the height of Shasta Dam to increase water storage capacity and maintain cold water for Chinook salmon (Oncorhynchus tshawytscha). Another potential threat is the fungus Batrachochytrium salamandrivorans, which has not yet been detected in North America but is lethal to related salamanders (Hydromantes strinatii) in Europe (Martel et al. 2014). In addition to these threats, recent genetic evidence suggests that the species as originally petitioned...
Static flood inundation boundary extents were created along the entire shoreline of Lake Ontario in Cayuga, Jefferson, Monroe, Niagara, Orleans, Oswego, and Wayne Counties in New York by using recently acquired (2007, 2010, 2014, and 2017) light detection and ranging (lidar) data. The flood inundation maps, accessible through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov/mission-areas/water-resources/science/flood-inundation-mapping-fim-program, depict estimates of the areal extent and water depth of shoreline flooding in 8 segments corresponding to adjacent water-surface elevations (stages) at 8 USGS lake gages on Lake Ontario. This item includes data sets for segment H - Lake Ontario...

This dataset presents water withdrawal estimates, consumption estimates, and associated information for 1,122 water-using, utility scale thermoelectric power plants in the United States for 2015. The U.S. Geological Survey (USGS) developed models to estimate thermoelectric water use based on linked heat-and-water budgets, including thermodynamically plausible ranges of minimum and maximum withdrawal and consumption, to provide a consistent method for water-use estimation across the fleet of U.S. thermoelectric plants. Historically, thermoelectric water withdrawal and consumption has been estimated by the Department of Energy's Energy Information Administration (EIA) based on surveys of plant operator-reported data...

The U.S. Geological Survey (USGS) worked in cooperation with the Federal Emergency Management Agency (FEMA) to document the October, 2016 storm event in North Carolina. The passage of Hurricane Matthew through central and eastern North Carolina during October 7-9, 2016, brought heavy rainfall which resulted in major flooding. More than 15 inches of rain were recorded in some areas. Over 600 roads were closed including Interstates 95 and 40, and nearly 99,000 structures were impacted by floodwaters. Immediately after the flooding, the USGS documented 267 high-water marks (HWM), of which 254 were surveyed. The North Carolina Emergency Management documented and surveyed 353 HWMs. Using a subset of these HWMs, six flood-inundation...

Daily streamflow discharge data from 139 streamgages located on tributaries and streams flowing to the Gulf of Mexico were used to calculate mean monthly, mean seasonal, and decile values. Streamgages used to calculate trends required a minimum of 65 years of continuous daily streamflow data. These values were used to analyze trends in streamflow using the Mann-Kendall trend test in the R package entitled “Trends” and a new methodology created by Robert M. Hirsch known as a “Quantile-Kendall” plot. Data were analyzed based on water year using the Mann-Kendall trend test and by climate year using the Quantile-Kendall methodology to: (1) identify regions which are statistically similar for estimating streamflow characteristics;...

Note: this data release is currently being revised and is temporarily unavailable. Publicly available geospatial data were identified, collated, and analyzed for a region of karst terrain extending from Albany to Buffalo, New York. A series of geospatial datasets were assembled to determine the location and extent of karstic rock; bedrock geology and depth to bedrock; average water-table configuration; surficial geology; soil type, thickness, and hydraulic conductivity; land cover; and closed depressions in the land surface First release: 2021 Revised: July 2022 (ver. 2.0) Revised: October 2022 (ver. 3.0) .
This data release provides a map of the time-averaged shear-wave velocity in the upper 30 m (Vs30) for California using the method described by Thompson and others (2014). There are two adjustments to the algorithm described by Thompson and others (2014), which is built on the geology-based Vs30 map by Wills and Clahan (2006). In this data release, we use the Wills and others (2015) updated geology-based Vs30 map. The second change is that we have adjusted the kriging procedure so that measured Vs30 values do not affect the predictions across distinctly different geologic units. July 2022 Update (ver. 2.0) Resolution is now 3 arcseconds instead of 7.5 arcseconds Fixed a code error that prevented some of the Vs30...

A goal of the USGS Earth Mapping Resources Initiative (Earth MRI) program, which partners the USGS with State Geological Surveys, Federal agencies, and the private sector, is to collect new geological, geophysical, geochemical, and topographic (lidar) data in key areas of the U.S., with the purpose of stimulating domestic mineral exploration and production of critical minerals. As a first step, the Earth MRI program identified regional geographic areas within the United States that may have potential to host deposits containing critical minerals. These are the focus areas described in Dicken and others (2022) (https://doi.org/10.5066/P9DIZ9N8). As a further step to meet Earth MRI priorities, mineral deposit information...
