Data in support of estimation of magnitude and frequency of floods for rural, unregulated streams in and near Virginia and West Virginia Data in support of estimation of magnitude and frequency of floods for rural, unregulated streams in and near Virginia and West Virginia
This data release contains the supporting datasets, tables, and geospatial information generated and analyzed in the 2025 flood-frequency study for Virginia and West Virginia. In this study, the magnitude and frequency of annual peak streamflows were estimated using the Expected Moments Algorithm for 813 streamgages on rural, unregulated streams in and near Virginia and West Virginia...
Status and trends in stream temperature, salinity, flow, hydromorphology, and biological assemblages across the Chesapeake Bay Watershed Status and trends in stream temperature, salinity, flow, hydromorphology, and biological assemblages across the Chesapeake Bay Watershed
The Chesapeake Bay watershed is home to over 18.5 million people and continues to experience rapid population growth. With changes in population and land development, understanding current conditions of streams within the watershed (status), and changes in condition over time (trends) is important for assessing stream health. This data release contains the output files for results of...
Upper Colorado River Basin Accumulated Wastewater Ratios and PFAS Model Predictions (ver. 2.0, August 2025) Upper Colorado River Basin Accumulated Wastewater Ratios and PFAS Model Predictions (ver. 2.0, August 2025)
A wastewater reuse model was applied to the Upper Colorado River basin to assess the (1) percent of accumulated wastewater (ACCWW%) from municipal and industrial wastewater treatment plants (WWTPs) in each initialized (that is, has an assigned hydrosequence number for flow-routing) National Hydrography Dataset Version 2.1 (NHDPlus V2.1) stream segment; and (2) predicted environmental
Per- and Polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2024 (ver. 2.0, September 2025) Per- and Polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2024 (ver. 2.0, September 2025)
These data were collected to understand the occurrence of per- and polyfluoroalkyl substances (PFAS) in drinking water samples at selected public water systems in West Virginia identified to have detections for PFAS above laboratory reporting levels in previously collected raw-water samples (McAdoo and others, 2022). These data are stored in the USGS National Water Information System...
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2024 Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2024
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed were calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2024. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach...
Estimated aquifer distribution for private-domestic wells; estimated spatial distribution of the self-supplied domestic population for 2020 and 2010; and estimated monthly self-supplied domestic withdrawals of groundwater for the Virginia Coastal Plain Estimated aquifer distribution for private-domestic wells; estimated spatial distribution of the self-supplied domestic population for 2020 and 2010; and estimated monthly self-supplied domestic withdrawals of groundwater for the Virginia Coastal Plain
The USGS developed methods and results to improve estimation of the aquifer system, location, and quantity of private-domestic well groundwater withdrawals and the self-supplied domestic population of the Virginia Coastal Plain. This USGS data release includes (1) tabular datasets with the estimated aquifer distribution of 8,264 private-domestic wells aggregated by locality/county, USGS...
Vertical Land Motion Global Navigation Satellite System Campaigns, Southeast Virginia, 2023 Vertical Land Motion Global Navigation Satellite System Campaigns, Southeast Virginia, 2023
This data release contains the original campaign survey files in Receiver Independent Exchange Format (RINEX) and summaries of the survey results for 9 vertical control points in the Hampton Roads region of southeastern Virginia. In this 2023 survey campaign, a subset of 9 the original 24 benchmarks were occupied with Global Navigation Satellite System (GNSS) antennas and receivers as...
Data for the Potomac River Watershed Accumulated Wastewater Viewer Data for the Potomac River Watershed Accumulated Wastewater Viewer
This data release contains measured streamflow data from U.S. Geological Survey (USGS) streamgages and reported wastewater data from wastewater treatment plants (WWTP) discharge monitoring reports (DMRs) within the Potomac River watershed between October 1, 2021 and September 30, 2024. Mean monthly streamflow data was obtained from 117 USGS streamgages (Table1_Streamgages.csv). Average...
Streamflow and precipitation data and characteristics of selected storms for four stream basins in West Virginia, 2017-2020 Streamflow and precipitation data and characteristics of selected storms for four stream basins in West Virginia, 2017-2020
In cooperation with the West Virginia Division of Transportation, Department of Highways (WVDOH), precipitation and streamflow were measured at four streamgages in West Virginia to compute time of concentration (Tc) and compare it to Tc estimates made using accepted methods. Precipitation and streamflow data were collected during 2017-2020. Storms were identified and classified through...
Fairfax County Monitoring Network 2007 - 2022: Annual Loads, Regression Models, and Ancillary Data Fairfax County Monitoring Network 2007 - 2022: Annual Loads, Regression Models, and Ancillary Data
Nitrogen (N), phosphorus (P), and suspended sediment (SS) loads in Fairfax County, Virginia streams were calculated using monitoring data from 5 intensively monitored watersheds for the period from water year (October - September) 2008 through 2022. Nutrient (N and P) and SS loads were computed using a surrogate (multiple-linear regression) approach with lab analyzed N, P, and SS samples...
Data from 126 logged groundwater wells analyzed to assess geologic, topographic, and physiographic controls on the occurrence and distribution of fractures and transmissivity of water-bearing fractures in West Virginia Data from 126 logged groundwater wells analyzed to assess geologic, topographic, and physiographic controls on the occurrence and distribution of fractures and transmissivity of water-bearing fractures in West Virginia
This data release summarizes 126 borehole geophysical logs collected in fractured rock aquifers within the state of West Virginia. Data includes site information for the wells logged, in addition to all fractures identified as part of processing of borehole logs collected for the study.
