This data release contains time-lapse imagery taken at U.S. Geological Survey (USGS) stream gaging stations with associated hydrologic and meteorological data related to each image. These data are to help improve the development of models in detecting water elevation at a given stream gaging station. Images of the water surface and surroundings at USGS stream gaging stations were taken at varying time intervals ranging between every five minutes to an hour. Cameras used include trail cameras, web cameras, and the custom river imagery sensing (RISE) camera. Time-lapse images for each USGS stream gaging station are provided in compressed files (file extension .7z). These files are named in a format to identify the...

A total of 27 temperature sensors were deployed along the lower 90 miles of the Yakima River at 7 locations where cold water had been previously observed. These 7 cold-water areas had 3 to 6 temperature sensors installed to document the extent and duration of these cold-water areas and their impacts on mainstem temperatures of the Lower Yakima River. Cold-water areas included the mouths of tributaries, alongside channels, and within alcoves. Sensor deployments ranged from 1 to 2 years beginning in October 2018. All temperature data are included in the Yakima.temperatures.zip folder. Details of each monitoring location are provided in the site.locs.csv file. In addition to the raw data and site location information,...

This dataset, VegDischarge v1, represents a significant contribution to the understanding of hydrological dynamics across Africa from 2000 to 2021. It encompasses high-resolution (1km x 1km) monthly raster data of deep drainage, surface runoff, and total runoff, derived from the VegET (VegetationEvapoTranspiration) hydrological model (Senay et al., 2023). Additionally, routed discharge data (Mizukami et al., 2021) for over 63,000 river segments is provided, employing different routing algorithms (DW, KW, KWT, MC, and IRF) to demonstrate variability in river discharge patterns. This comprehensive dataset is stored in NetCDF and Shapefile formats, offering valuable insights for policymakers, stakeholders, and researchers...

This data release includes data processing scripts, data products, and associated metadata for a study investigating trends in Mississippi River nitrogen and phosphorus loads to the Gulf of Mexico. This data release consists of three main components: 1) Nitrogen and phosphorus balances and accumulation, which account for major nutrient inputs (fertilizer, manure, waste water treatment facility effluent, atmospheric deposition, weathering and nitrogen fixation) and outputs (crop harvest and removal and gaseous emissions of nitrogen). Annual balances and total accumulation are estimated for the entire Mississippi River Basin, which covers 2,887,854 km2 for the time period from 1950 to 2017, 2) Weighted Regression...

In support of a preliminary analysis performed by New York State Department of Environmental Conservation (NYSDEC) that found elevated nutrient levels along selected reaches of the Mohawk River, one-dimensional, unsteady, hydraulic and water-quality models using HEC-RAS and HEC-RAS Nutrient Simulation Module I (version 5.0.3) were developed by the U.S. Geological Survey (USGS) for the 127-mile reach of the Mohawk River between Rome and Cohoes, New York. The models were designed to accurately simulate within-channel flow conditions for this highly regulated, control structure dense river reach. The models were calibrated for the study period of May through September 2016 using best available streamflow, temperature,...

This dataset contains site information and results of flood-frequency analysis for 139 urban streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina. Developed imperviousness in the basins, based on the 2011 National Land Cover Database, was at least 10 percent (Homer and others, 2015). Drainage areas of the streamgage basins ranged from 0.15 - 161 square miles. Annual peak-flow data from the 1947 - 2022 water years were used in the study (U.S. Geological Survey, 2024). Peak-flow (.pkf), specification (.psf), output (.PRT), and export (.EXP) files from flood-frequency analysis in USGS PeakFQ...

This data release provides results from a watershed modelling effort to depict the use of natural infrastructure in dryland streams (NIDS), i.e., gabions, as a low-tech and low-cost, nature-based solution for increased water availability in the Buckeye area, west of the White Tank mountains and northwest of Phoenix, AZ, USA. Our goal was to identify impacts of current management and hypothetical installation of gabions, as NIDS to offset expected impacts of planned development (Norman et al., 2022; Tosline & Swick, 2023). This release and associated report (Norman & Petrakis, 2024) describes the methods and results acquired for modeling installation of gabion-style NIDS and the impacts at the apex and outlet of...

The U.S. Geological Survey (USGS), as part of the Next Generation Water Observing System (NGWOS) has collected discrete stream samples for analysis of suspended-sediment concentrations at eight real-time streamflow and water-quality monitoring (turbidity and suspended sediment) stations located in Pennsylvania, New Jersey, and New York in the Delaware River Basin. Data were collected from 2019-2022 at these stations for the application of predicting suspended-sediment concentrations using real-time continuous turbidity, suspended sediment from an uncalibrated sensor, and streamflow data. Regression equations were developed by relating discrete-sample suspended sediment and continuous turbidity, suspended sediment...

From October 2017 through September 2022, the National Water Quality Network (NWQN) monitored 110 surface-water river and stream sites and more than 1,800 groundwater wells for a large number of water-quality analytes, for which associated quality-control data and corresponding statistical summaries are included in this data release. The quality-control data—for samples that were collected in the field (at all 110 surface-water sites, 350 groundwater wells, and 16 quality-control-only sites), prepared in the laboratory, or prepared by a third party—can be used to assess the quality of environmental data collected by the NWQN through the estimation of bias and variability in reported results. The general analyte...

Estimates of various low-flow statistics were computed at 56 ungaged stream locations throughout New Jersey during the 2022 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with applications at partial-record streamgaging stations in New Jersey (Colarullo and others, 2018). The estimates are computed as needed for use in water resources permitting, assessment, and management by the New Jersey Department of Environmental Protection. The data release includes the stream name, location, drainage area, method of estimation,...

In October 2023, the U.S. Geological Survey Idaho Water Science Center (IDWSC), in cooperation with Lucky Peak Power Plant Project (LPPPP), completed bathymetric and topographic surveys at two dam intake structures using multibeam bathymetry and boat-mounted Light Detection and Ranging (LiDAR). Dam operators indicated a possibility that sediment aggradation was occurring near the intake structures that allow water to pass through the dam. The bathymetric and topographic data generally include complete coverage near the intake structures and banklines near Lucky Peak Dam.
