National Water Dashboard (NWD)
The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.
Visible and near-infrared spectroscopy for sediment samples collected across North-eastern U.S.
This data record contains a CSV file with spectral reflectance (420-2114 nm) for sediment samples collected from each of four source locations (cropland, stream bank, glaciolacustrine, and street dust) located across sites in the Northwestern US during prior studies. Data were collected in a laboratory setting using Spectrecology USB4000-VIS-NIR and NIRQuest512-2.2 spectrometers.
SPARROW model input datasets and predictions of nitrogen loads in streams of the Chesapeake Bay watershed
This data release contains mean-annual total nitrogen (TN) loads predicted by a SPARROW model for individual stream and shoreline reaches in the Chesapeake watershed as defined by NHDPlus, a 1:100,000 scale representation of stream hydrography built upon the National Hydrography Dataset (NHD) (Horizon Systems, 2010).
Data for Specific Gage Analysis on the Patapsco River, 2010-2017
The U.S. Geological Survey, in collaboration with American Rivers and other partners, conducted a monitoring program beginning in 2010 to track river response to a series of dam removals on the Patapsco River intended to restore anadromous fish habitat in the watershed.
Ephemeral channel heads and digital elevation models used to extract stream networks in Clarksburg, MD
This dataset describes the location of channel heads survyed in two headwater watersheds in Clarksburg, Montgomery County, Maryland, and the digital elevation models derived from light detection and ranging (lidar) covering the two watersheds. The digital elevation models were used to derive topographic attributes used to delineate drainage networks that were then assessed for accuracy using...
Water bodies within 500 meters of poultry feeding operations on the Delmarva Peninsula in 2016 and 2017.
Data release contains 1710 polygons representing small bodies of water within 500 meters of poultry feeding operations on the Delmarva Peninsula. Ponds were identified using the USDA's National Agriculture Imagery Program's 2016 and 2017 products. Poultry feeding operations were described in location by Soroka and Duren (2020).
Annual spring nitrogen fluxes for nine Chesapeake Bay tributary monitoring sites, 1985 to 2020
Data release includes the U.S. Geological Survey (USGS) estimate of spring nitrogen fluxes from nine tributaries to the Chesapeake Bay from 1985 to 2020. Data are presented from tributaries within the USGS River Input Monitoring (RIM) network identified by site numbers: 01491000, 01578310, 01594440, 01646580, 01668000, 01673000, 01674500, 02035000, 02041650. Periods of
Contiguous U.S. annual snow persistence and trends from 2001-2020
Snow persistence (SP) or the snow cover index (SCI), is the fraction of time that snow is present on the ground for a defined period. Cloud covered index (CCI) is the fraction of time that there is no data, cloud, or sensor saturation for the same period. SP and CCI were calculated on a pixel by pixel basis using MODIS/Terra Snow Cover 8-Day L3 Global 500m Grid, Collection 6
Low-streamflow and precipitation trends for 183 U.S. Geological Survey streamgages in the Chesapeake Bay Watershed.
This data release contains low-streamflow trend results from 183 U.S. Geological Survey (USGS) streamgages and precipitation trend results from gaged watersheds within the Chesapeake Bay Watershed. Data include streamgage identification number, trend slopes and significance for several low-streamflow and precipitation metrics.
Groundwater Quality and Plume Boundaries for Select Contaminants of Concern at Badger Army Ammunition Plant, Wisconsin (2000 – 2018)
This dataset describes concentrations of select contaminants in groundwater, collected at monitoring wells in the vicinity of the Badger Army Ammunition Plant in Sauk County, Wisconsin, between 2000 - 2018. The data were used to assess trends in contaminant concentrations over time, delineate plume boundaries at various time intervals, and assess the overall monitoring network at the Ba
Analytical Results for Ground Water Quality Monitoring Wells Around Badger Army Ammunition Plant, Wisconsin, 2000-2018
This dataset describes concentrations of select contaminants in groundwater, collected at monitoring wells in the vicinity of the Badger Army Ammunition Plant in Sauk County, Wisconsin, between 2000 - 2018. The original water quality data were compiled by the U.S. Army Environmental Command (AEC) and SpecPro Professional Services and provided to the U.S. Geological Survey (USGS). A
2,4-DNT Plume Boundaries
This dataset describes plume boundary extents for 2,4-dinitrotoluene (2,4-DNT) in the vicinity of the Badger Army Ammunition Plant in Sauk County, Wisconsin for various time intervals between 2000 - 2018.
