Data

This dataset contains satellite-derived information on lake elevations for selected glacial dammed lakes (GDLs) monitored by the National Weather Service Alaska-Pacific River Forecasting Center in Anchorage, Alaska, as well as several Alaska lakes collocated with monitoring gages. The lake elevation data are derived from satellite-observed water surface elevations from the Surface Water...

The recently launched Surface Water and Ocean Topography (SWOT) satellite provides observations of Earth’s rivers and lakes, which sets the stage for innovative application of such data for hydrologic analysis. Here, we apply the LakeFlow algorithm, which leverages mass conservation principles and Bayesian optimization, to estimate lake inflow and outflow discharge at 1,061 North...

Multiple sources of mine drainage including discharge from the abandoned Dinero mine tunnel and two gulches flow into a wetland, known herein as the Dinero wetland along the Lake Fork Creek corridor. The Dinero wetland is approximately xx acres in extent. The Dinero wetland is being considered as a location for passive treatment of the mine drainage flowing through it. As such, study...

This data release provides maps of estimated performance metrics for the remotely sensed evapotranspiration (ET) models within the OpenET ensemble, at the scale of the conterminous U.S. (CONUS). It also provides relative weight maps for each of the ensemble models that can be used to produce performance-weighted ensemble estimates. These maps are provided at a 4 kilometer spatial...

The USGS is conducting a long-term study of a terrestrial crude oil spill that resulted from a ruptured pipeline in 1979. Samples of oil bailed from wells were analyzed for polyaromatic hydrocarbons by a commercial lab. A total of 32 samples were analyzed in three batches. A sample that serves as a surrogate for the original spilled oil was submitted with each batch. For each oil sample

A Lagrangian study was conducted in 2019 that followed two water masses in the Powder River from central Wyoming to southeastern Montana. The study characterized the changes of the in-stream transport of sediment and associated chemical and biological constituents. Depth-integrated water samples (using an isokinetic nozzle) and river bottom sediment samples were collected at six mainstem...

Needle samples from 140 Pinus ponderosa were analyzed for trace elements via inductively coupled plasma mass spectrometry (ICP-MS). Samples were collected from eight locations representing five distinct soil types across the Colorado Plateau near Flagstaff, Arizona and Boulder, Colorado. Data includes a full spectral scan between m/z 5-245 which was condensed to 72 dominant atomic masses

Sediment samples from sites affected by environmental releases of wastewater from oil and gas production were examined to determine sorbed versus mineral structure associations of barium, radium, strontium, and other elements. Archive samples were used from work at Blacktail Creek, North Dakota and Wolf Creek, West Virginia. The Blacktail Creek samples are described in publications and...

This metadata record documents four 30-meter raster data layers; 1) elevation, 2) hydro-enforced elevation, 3) flow direction, and 4) flow accumulation for the conterminous United States. The datasets are derived from the NHDPlus Version 2.1 regional raster datasets and presented here as Cloud Optimized GeoTIFFs (COGs).

This data release provides aerial images acquired through the National Agricultural Imagery Program (NAIP) used to test a method for inferring image acquisition time from shadow orientation. For many applications, such as linking remotely sensed data to streamflow recorded at a gaging station, knowing the time an image is acquired is important, but such metadata often is not available...

This data release contains concentration and isotope-dilution standard (IDS) recovery data from individual samples that are summarized and interpreted in the U.S. Geological Survey (USGS) Techniques and Methods (T&M) Report "Determination of Per- and Polyfluoroalkyl Substances in Water by Direct Injection of Matrix-Modified Centrifuge Supernatant and Liquid Chromatography-Tandem Mass...

This data release contains three different estimates of road deicing salt applications, which utilize different sources of deicing salt data, and climate, land cover, and imperviousness data to provide spatially distributed estimates of deicing salt application for states covering the Delaware River Basin from water and calendar years 2001 through 2023 at a 30-meter spatial resolution...
