Water quality and contaminants in stream surface waters collected in Southeast Pennsylvania and Maryland Piedmont mixed agriculture, 2023 Water quality and contaminants in stream surface waters collected in Southeast Pennsylvania and Maryland Piedmont mixed agriculture, 2023
This data release contains the concentration and quality assurance results for 30 streams, sampled twice. In 2023, the typology sampled was Pennsylvania and Maryland Piedmont mixed agriculture. Each dataset consisted of 30 sampling sites. Samples were analyzed for the following constituent classes (count of constituents); field and water-quality parameters (9), nutrients/anions (13)...
Monthly and daily twelve-digit hydrologic unit code aggregations of the WRF-Hydro modeling application with CONUS404BA Atmospheric Forcings, 1979-2022 Monthly and daily twelve-digit hydrologic unit code aggregations of the WRF-Hydro modeling application with CONUS404BA Atmospheric Forcings, 1979-2022
This data release contains spatially and temporally aggregated data from a particular application of the Weather Research and Forecasting hydrological model (WRF-Hydro; Gochis and others, 2025) from water year 1980 through 2022 for the conterminous United States (Rafieeinasab and others, 2026). This modeling application is climatologically forced with a modified version of the CONUS404...
Electrical resistivity tomography (ERT) data collected near Summerset, South Dakota, between July 28 and August 5, 2025 Electrical resistivity tomography (ERT) data collected near Summerset, South Dakota, between July 28 and August 5, 2025
The U.S. Geological Survey, in cooperation with the City of Summerset, South Dakota, performed electrical resistivity tomography (ERT) surveys between July 28 and August 5, 2025. ERT data were collected using an Advanced Geosciences Incorporated SuperSting with 2 passive cables with 14 electrodes per cable. In total, ERT data were collected along 13 transects using 2 passive cables and...
Model predictions of biological condition metrics for small streams in the Chesapeake Bay Watershed, USA from 1985 to 2023 Model predictions of biological condition metrics for small streams in the Chesapeake Bay Watershed, USA from 1985 to 2023
This data release contains predictions of stream biological condition as defined by the Chesapeake basin-wide index of biotic integrity for stream macroinvertebrates (Chessie BIBI) as well as prediction of the percentage of the benthic macroinvertebrate assemblage as 1) Ephemeroptera, Plecoptera, Trichoptera less Hydropsychidae, 2) Ephemeroptera, and 3) Clingers using Random Forest...
CE-QUAL-W2 theoretical dam operational scenarios for select U.S. Army Corps of Engineer reservoirs and tributaries downstream of U.S. Army Corps of Engineer dams in the Willamette River Basin, Oregon: 2011, 2015, and 2016 CE-QUAL-W2 theoretical dam operational scenarios for select U.S. Army Corps of Engineer reservoirs and tributaries downstream of U.S. Army Corps of Engineer dams in the Willamette River Basin, Oregon: 2011, 2015, and 2016
Reservoir outflows and downstream water temperatures in the Willamette River Basin, Oregon, are influenced by the operation of 13 U.S. Army Corps of Engineer (USACE) dams that comprise the Willamette Valley System (WVS). CE-QUAL-W2 models have been developed to simulate water release temperatures from a subset of WVS dams, and thermal effects to downstream reaches that may result from...
Results of weighted least-squares (WLS) regression for 42 USGS streamgages in urban areas in Alabama and Mississippi Results of weighted least-squares (WLS) regression for 42 USGS streamgages in urban areas in Alabama and Mississippi
This dataset contains results of weighted least-squares (WLS) regression for 42 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) on urban streams in Alabama and Mississippi. WLS regression was used to relate drainage area and the percentages of the drainage basins of the streamgages in developed land use (the sum of classes 21-24 from the 2011...
