Coal‑fired power plants generate large volumes of coal combustion products (CCPs) that can release trace elements to groundwater. Conventional geochemical indicators such as major ions and trace metals can signal CCP impacts but may be insufficient when background concentrations are naturally elevated or when multiple contaminant sources exist. Stable isotope ratios provide an additional...

In this dataset, there are three tabular data (.csv) files that provide: a) data on physical measurements (length, weight) of test individual fish (rows) and their immediate and delayed (12, 24, 36, 48, and 96 h) post-test mortalities (Fish Metrics and Mortality.csv); b) data on conditions for each test trial (rows) of the pneumatic lift at three test lift heights, the resultant number...

40Ar/39Ar geochronologic data presented in this data release are for a basaltic tuff exposed in a paleoseismic trench across the Anvil Lake fault, Clackamas River fault zone, Oregon. These data were collected to determine the age of volcanic bedrock in the footwall of the Anvil Lake fault, exposed during the paleoseismic trench study. These data provide constraints for the slip rate of...

40Ar/39Ar data presented in this data release are from the Tumalo volcanic center in central Oregon, which consists of predominantly rhyolitic to dacitic pyroclastic flows, tephra fallout deposits, cinder cones, domes, and lava flows. Data is presented for thirteen volcanic units from the Tumalo volcanic center, including three major ignimbrite eruptions (the Desert Springs Tuff, the...

Bias-corrected estimates of high and average water table elevation and depth below the land surface were generated for areas near the southern part of Puget Sound, Washington, on a 500‑ft‑by‑500‑ft grid. Simulated water table elevations were extracted from two published U.S. Geological Survey groundwater flow models, the Southeast Sound (SES) model (Long and others, 2024) and the Kitsap...

This data release provides a documentation of datasets and code used in a fisheries management analysis and a model application to reproduce results.

This data release archives Kentucky digital elevation models (DEM), flow accumulation rasters (FAC), flow direction rasters (FDR), and stream drainage rasters (STR) (hereafter, the combination of these are referred to as ‘fundamental layers’). These fundamental layers were developed to update the layers in StreamStats to the best available data (StreamStats | U.S. Geological Survey). The...

The data provided were used in a mark-recapture analysis conducted in 2026. Environmental covariates included water quality and Upper Klamath Lake surface elevation. Raw data were downloaded from the USGS Oregon Water Science Center for multiple sampling sites (422622122004000_MDNL_2026-4-13.csv, 422622122004003_MDNU_2026-4-10.csv, 422042121513100_RPT_2026-4-10.csv, 422719121571400_WMR...

The U.S. Army Corps of Engineers American River Watershed Common Features project (ARCF) seeks to reduce flood risk for the City of Sacramento, California, and surrounding areas and improve fish access to additional habitat. The project includes levee-remediation measures to address seepage, stability, erosion, and height concerns as well as the widening of the Sacramento Weir and Bypass...

This data release contains the output from the analysis of the intensity to human water budget modification following the standards of Weiskel and others (2007) according to hydrologic regions of the conterminous United States (CONUS) by Van Metre and others (2020). Initial water budget data were produced by Martinez and others (2026) by combining the monthly water balance from water...

This data release provides a vector digital dataset developed from the published metamorphic map on the Centennial geologic map of Vermont. This data release is a digital representation of the metamorphic map shown on the bedrock geologic map of Doll and others (1961). The original publication from 1961 was is available in as paper only. A scanned raster version of the 1961 map was...

Portions of the western U.S. are experiencing simultaneous increases in wildfire frequency, size, and intensity alongside worsening drought conditions. Despite the importance of quaking aspen (Populus tremuloides Michx.) as a keystone species, drivers of wildfire in aspen forests remain relatively understudied compared to neighboring vegetation types. These data supported investigation...
