Data

This data release contains model-calibration datasets in comma-separated value (CSV) format and model archive summaries in portable document format (PDF) for regression models developed to estimate suspended-sediment concentrations (SSC) at three U.S. Geological Survey monitoring stations along the Yellow River in northwestern Indiana (05516665 Yellow River near Oak Grove, IN; 05517000...

Methane is generated in subsurface hydrocarbon reservoirs through thermogenic and biogenic processes. Whereas thermogenic methane occurs through geological processes and time and is largely fixed with respect to production, microbial methanogenesis can be stimulated through the addition of nutrient amendments or bioaugmentation. The U.S. Geological Survey is actively researching the...

This data release contains estimates of the inflow and outflow components of a groundwater budget for San Juan County, Washington, and includes a Soil-Water-Balance (SWB) model used to estimate groundwater recharge, bias-corrected output from the SWB model, and detailed water use estimates. Groundwater recharge estimates were calculated by bias correcting SWB model net infiltration...

This U. S. Geological Survey (USGS) data release includes data for stream water, stream sediment, soil, and soil leachates for material collected in Lemhi County, Idaho to support a Mineral Resources Program funded study of mining and wildfire effects on water quality and aquatic ecosystem stability following the 2022 Moose Fire. The fire burned over 130,000 acres in Upper Napias, Arnett...

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...
