Data

This data release compiles concentrations of biomass-burning biomarkers, including the monosaccharide anhydride levoglucosan and its stereoisomers mannosan and galactosan, measured in water samples collected during the summer of 2018 in the Green Lakes Valley (GLV) watershed of the Colorado Front Range (Table_1_Site_Locations.csv and Table_2_Constituents_Analyzed.csv). Sampling sites are...

This is accompanying data produced for the study "Implications of Model Selection: Inter-Comparison of Publicly-Available, CONUS-Extent Hydrologic Component Estimates". These datasets were converted from their primary structures (rasters and shapefiles) to EPA Ecoregions Level I. Conversion was performed by averaging timestep layers via mean area weight to produce a single vector of...

This dataset includes model projections of seasonal temperature (T), precipitation (P), and runoff (R) from 214 climate simulations from coupled model intercomparison project (CMIP) 3 and CMIP5 scenarios for 19-year periods centered on 2030, 2060, and 2090. The summaries of the climate model projections are presented as percentiles (5th, 25th, 50th, 75th, and 95th) of seasonal (October...

Agricultural activities can impact water quality and the health of aquatic ecosystems. A conceptual framework was developed that combined generalized concepts on the movement of water, the environmental behavior of chemicals and eroded soil, and the designed functions of various agricultural activities. The framework addresses the impacts on water quality of a broad range of agricultural...

This model archive provides all data, code, and model outputs used in the corresponding manuscript (Barclay and others, 2026) to test machine learning (ML) methods for downscaling and multi-scale modeling of stream temperature to combine an ML model and/or input data at coarse spatial resolution with an ML model and/or input data at fine spatial resolution to predict stream temperatures...

This data release package contains water-use estimates from 1985 to 2015 aggregated to 8-digit Hydrologic Unit (HUC8), county, and aquifer level for the United States. The U.S. Geological Survey (USGS) is responsible for estimating water-use in the United States. In cooperation with local, State, and Federal agencies, the USGS has published estimates of water use in the United States...

Between May 2022 and April 2023, 57 passive seismic measurements were collected in select subwatersheds and arroyos near Los Planes, Mexico. The horizontal‑to‑vertical spectral ratio (HVSR) method is a passive seismic technique that uses a three‑component seismometer to measure the vertical and horizontal components of seismic noise in the range of ~0.3 to 40 Hertz (Hz). Common sources...

News articles which described issues of water availability in the Upper Colorado River Basin were retrieved from the Lexis Nexis database. Articles covered the period January 1, 2000 to March 2, 2024. Thematic coding was used to assess how media described risks associated with water availability, the consequences of and responses to those risks. These data support a multidisciplinary...

Fiber-Optic Distributed Temperature Sensing (FO-DTS) measurements were collected along the Tuolumne River within the Dos Rios Ranch area of River Partners restored floodplain properties, located downstream of Modesto, California. The deployment site was selected because the river at this location flows between a restored riparian floodplain on the left bank and an rip-rap bank stabilized

This data release provides spreadsheets of slope values between actual evapotranspiration and 13 equations for potential or reference evapotranspiration, evaluated at annual or daily time scales. The data release also provides the data underlying supporting tables and figures in the associated paper.

This data release contains prepared input attributes, monthly streamflow observations (minimum, mean, and maximum of the daily mean streamflow within each month), model outputs (predicted mean), and the code used to fetch and process these data. Code is also provided to generate confidence intervals for the mean, and prediction intervals using the built Random Forest models. Random...

This data release contains image velocimetry results derived from the publicly available Video Globe Challenge 2020 (VGC2020) dataset, processed using the U.S. Geological Survey's IVyTools software application (version 1.4.0.0). The original VGC2020 dataset includes eight videos of riverine flow conditions, each accompanied by reference discharge values and associated uncertainties. In...
