Data

Within New Jersey’s Raritan Basin Water Supply Complex, multiple lakes and reservoirs with persistent and recurrent cyanobacterial harmful algal blooms (cyanoHABs) discharge water which ultimately travels downstream in surface water to drinking-water intakes. Cyanobacteria and other water-quality data were collected as part of a collaborative study among multiple agencies, including the...

In cooperation with the Tennessee Wildlife Resources Agency (TWRA) and University of Tennessee Knoxville (UTK), the U.S. Geological survey (USGS) collected cyanobacterial toxin concentrations (i.e., microcystin, anatoxin, cylindrospermopsin, and saxitoxin) and water-quality field data at 4 sites on the Clinch River from November 2020 to December 2023. The goal for the sample data was to...

In cooperation with the Tennessee Department of Environment and Conservation (TDEC), the U.S. Geological Survey (USGS) measured cyanobacterial toxin concentrations (i.e., microcystin, anatoxin, cylindrospermopsin, and saxitoxin) and collected water-quality field data at 18 sites in North-central Tennessee from August 2022 to November 2024. Additionally, selected sites also were sampled...

This data release presents cyanotoxin and multiparameter water-quality sonde data collected from July-October 2020, at eleven sites in the Salem River, New Jersey. Data-collection sites included seven flowing and four impounded reaches of the main stem Salem River. Solid Phase Adsorption Toxin Tracking (SPATT) samplers were deployed at 11 sampling locations during the study period and...

This dataset is comprised of cyanotoxin concentrations in extracts from solid phase adsorption toxin tracking (SPATT) samplers deployed at fixed sampling stations in the Sacramento-San Joaquin Delta, beginning in 2020. SPATT samplers are a form of passive sampler constructed of adsorbent resin beads that concentrate cyanotoxins over time. Cyanotoxin congeners were measured from SPATT...

This dataset is comprised of cyanotoxin concentrations from whole water cyanotoxin samples collected at water quality stations in the Sacramento-San Joaquin Delta, beginning in 2020. Cyanotoxin congeners were measured from whole water cyanotoxin samples within the cyanotoxin classes: microcystins, anatoxins, cylindrospermopsins, saxitoxins, anabaenopeptins, and nodularin. Concentrations...

This data release contains measured stream discharge and total dissolved solids (TDS) data and estimated values for daily stream TDS loads, daily baseflow discharge, and daily baseflow TDS loads for 205 locations in the Upper Colorado River Basin. The estimated values, which represent conditions between 10/1/1985 and 9/30/2020, were obtained using the Weighted Regressions on Time...

This dataset provides estimated daily ice cover fractions for 107,257 lakes across the Northern Hemisphere from 1980 to 2022. The ice cover fractions were generated using a deep learning model trained on Landsat observations. The model's code is publicly available in the USGS GitLab repository: https://doi.org/10.5066/P13ZGUGE. The dataset consists of 42 CSV files, each corresponding to...

This model application data release provides the data processing and model code used to generate predictions of daily stream water temperature across the contiguous United States from 1979-2021. We used a recurrent graph convolutional network (RGCN) algorithm to make daily stream temperature predictions. Stream water temperature observations, along with forcing data consisting of daily

Potential evapotranspiration (PET) and reference evapotranspiration (ETo) are estimated at an approximately 1-kilometer spatial grid and daily time-step from January 1, 2024 to December 31, 2024 for Florida, Alabama, Georgia, South Carolina, and parts of Mississippi, North Carolina, and Tennessee. PET and ETo were computed from solar radiation, meteorological data (min/max temperature...

Potential evapotranspiration (PET) and reference evapotranspiration (ETo) are estimated at an approximately 2-kilometer (approximately 0.019 degrees longitude and 0.018 degrees latitude) spatial grid and daily time-step from January 1, 2024 to December 31, 2024 for the entire State of Florida. PET and ETo were computed from solar radiation, meteorological data (min/max temperature, min...

This data release contains three variables from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System (NHM-PRMS) version 1.1 modeling application forced with CONUS404-BA (Markstrom and others, 2024) from January 1st, 1980 through September 25th, 2021 that are summarized to a twelve-digit hydrologic unit code for the spatial extent of the conterminous...
