Data

Through data sharing agreements with Federal and State agencies, the U.S. Geological Survey (USGS) collects time-series of environmental management practice data to inform studies that guide resource management decisions. These data include agricultural conservation practices, best management practices (BMPs), and pollution control strategies in the Chesapeake Bay watershed. This data...

This data was created to support the Washington D.C. StreamStats project funded by the Washington D.C. Department of Energy and Environment (DOEE). This dataset contains basin characteristics for 154 urban streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in Delaware, District of Columbia, Maryland, New Jersey, Pennsylvania, and Virginia...

This dataset contains 3,229 feather files with time series of all model inputs for machine learning models predicting streamflow drought across the conterminous United States (CONUS). Files contain weekly time series of streamflow percentiles, meteorology, snow water equivalent, forecast meteorology, estimated water use, soil moisture, as well as lagged versions of these datasets. Values...

U. S. Geological Survey (USGS) scientists completed a data collection campaign from the 3rd of April to the 23rd of June in 2023, using various methods to record geomorphic and habitat indicators throughout 30 streams in southern Pennsylvania and northern Maryland. Field methods included GNSS surveys, gravelometer-based pebble count readings, visual assessments, and riparian analyses...

Dynamic Surface Water Extent (DSWE) Annual Proportions data summarize occurrence of water on the land surface. DSWE Annual Proportions data are statistical summaries of the USGS Landsat Collection 2 Level-3 DSWE data product (C2-DSWE), a raster dataset of per-pixel surface water inundation status based on the analysis of Landsat 4-9 satellite imagery. DSWE Annual Proportions data average

This dataset contains topographic, climatic and land cover attributes for headwaters (stream orders 1 and 2 ) as defined by the National Hydrography Dataset High Resolution (NHDHR) and downstream areas (stream orders 3 and up) for a subset of Conterminous United States (CONUS) HUC12s. Specifically, this dataset contains 2021 National Land Cover Database (NLCD) land cover for the...

Digital imagery was obtained by Elevated Media Concepts LLC from small unmanned aerial systems (UAS), over Historic Ellicott City on June 18, 2018 after major flooding events. The imagery was collected to document and monitor effects of flooding, including property damage and erosion in Ellicott City, Maryland. A DJI Inspire 2 quadcopter with camera model FC6520 and a DJI Mavic Pro...

This metadata record contains 14 tables of biogeochemical data collected to evaluate the fate and transport of chlorinated ethenes in Area B groundwater, Fort Detrick, Frederick, Maryland collected during 2018-2020. Included in the dataset are (1) FtD_All_Constituents_NA_2019: concentrations of all non-VOC constituents analyzed as part of the natural attenuation sampling event in 2019,...

This metadata record consists of 16 tables containing data generated from laboratory experiments of trichloroethene (TCE) biodegradation and during field characterization and performance monitoring of a groundwater bioremediation pilot test conducted at Site K, Former Twin Cities Army Ammunition Plant, Arden Hills, Minnesota. The data was collected from December 2020 through December...

This metadata record documents one comma delimited table that contains information on the grain size distribution, fallout radionuclide activity, and geochemical characteristics of urban sediments within the Hickey Run watershed in Washington, D.C. Measurements include radiological activity, sediment particle size information, and elemental composition of source and target sediments.

This metadata record contains one table and one shapefile with results from field sampling at locations of groundwater discharge (seeps) identified by autonomous boat survey at the Lower Darby Creek Area (LDCA) Superfund Site, near Folcroft, Pennsylvania, in 2024. Included in the dataset are (1) PFAS concentrations, volatile organic compound (VOC) concentrations, cations/trace metals...

This metadata record consists of 3 tables containing per-and-poly-fluoroalkyl substances (PFAS) and polychlorinated biphenyls (PCB) concentration data of wastewater and biosolid samples from wastewater treatment plants within the Patapsco and Potomac watersheds. The PCB concentration data was used to assess the occurrence and fate of PCB in wastewater treatment plants within the Patapsco...
