Potomac River ADCP Bathymetric Survey, October 4-7, 2021 Potomac River ADCP Bathymetric Survey, October 4-7, 2021
Bathymetric LiDAR technology was used to collect riverbed elevation data along the Potomac River. In support of this effort, a bathymetric survey with a boat-mounted acoustic Doppler current profiler (ADCP) was conducted in the study area during October 4-7, 2021. The study area consisted of four verification reaches on the Potomac River including: 1) Williamsport accessed through the...
Virginia Bridge Scour Pilot Study Streamflow Data Virginia Bridge Scour Pilot Study Streamflow Data
The objective of the Virginia Bridge Scour Pilot Study is to investigate methods for improving the utility of estimates of hydrologic flow in streams and rivers used when evaluating potential pier scour over the design-life of highway bridges in Virginia. Data measuring daily discharge and instantaneous discharge were required for analysis. The provided daily value and instantaneous...
Inputs and Selected Outputs Used to Assess Stormwater Quality and Quantity in Twelve Urban Watersheds in Hampton Roads, Virginia, 2016 - 2020 Inputs and Selected Outputs Used to Assess Stormwater Quality and Quantity in Twelve Urban Watersheds in Hampton Roads, Virginia, 2016 - 2020
Nitrogen (N), phosphorus (P), and total suspended solids (TSS) loads, in Hampton Roads, Virginia stormwater conveyance systems have been calculated using monitoring data from 12 intensively monitored watersheds for the period from water year (October - September) 2016 through 2020. Nutrient and TSS loads were computed using a surrogate (multiple-linear regression) approach with lab...
Environmental Sampling of Per- and Polyfluoroalkyl Substances in the Middle Chickahominy River Watershed, Virginia, 2021-2022 (ver. 2.0, September 2023) Environmental Sampling of Per- and Polyfluoroalkyl Substances in the Middle Chickahominy River Watershed, Virginia, 2021-2022 (ver. 2.0, September 2023)
These data were collected to understand the occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in the middle Chickahominy River watershed. Specifically, this effort was initiated to: 1. Determine concentrations of PFAS in surface water at select locations in the middle Chickahominy River watershed; 2. Determine concentrations of PFAS in edible portions of fish at select locations...
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2021 Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2021
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2021. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach...
Ecological Data Mapper Ecological Data Mapper
This application was created to visualize and interact with the ecological data from the ongoing monitoring effort on two previously restored streams in Reston, Virginia - Snakeden Branch and The Glade. The “Reston monitoring program” includes the measurement of hydrologic, water-quality, and ecological data and evaluations of changes in these measurements over time. For more information...
Shapefiles of hydrogeologic unit extents and top-surface altitude contours used in the revised hydrogeologic framework for the Virginia Coastal Plain Southwest of the James River Shapefiles of hydrogeologic unit extents and top-surface altitude contours used in the revised hydrogeologic framework for the Virginia Coastal Plain Southwest of the James River
A revision to the hydrogeologic framework of the Virginia coastal plain southwest of the James River was developed by USGS during 2019-2021. This revision includes modifications to existing understanding of the groundwater system in Prince George, Surry, Sussex, Isle of Wight, and Southampton counties and the cities of Franklin and Suffolk in southeast Virginia. This USGS data release...
Data Collected to Assess the Occurrence and Distribution of Per- and Polyfluoroalkyl Substances in West Virginia Public Source-Water Supplies, 2019 - 2021 Data Collected to Assess the Occurrence and Distribution of Per- and Polyfluoroalkyl Substances in West Virginia Public Source-Water Supplies, 2019 - 2021
Source water for West Virginia’s public water systems is pumped from groundwater aquifers or withdrawn from the state’s rivers and lakes. These systems provide drinking water to a majority of the state’s population and require constant monitoring for known and emerging contaminants. Groundwater contamination from Per- and Polyfluoroalkyl Substances (PFAS) has occurred in West Virginia...
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay Nontidal Network stations: Water years 1985-2020 (ver. 2.0, January 2023) Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay Nontidal Network stations: Water years 1985-2020 (ver. 2.0, January 2023)
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations stations for the period 1985 through 2020. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach...
Benthic macroinvertebrate, fish, and physical habitat data for selected streams in Reston, VA Benthic macroinvertebrate, fish, and physical habitat data for selected streams in Reston, VA
The United States Geological Survey Virginia and West Virginia Water Science Center (USGS VA-WV-WSC) and Fairfax County assembled this data release in support of ongoing USGS VA-WV-WSC monitoring and evaluations of stream conditions overtime of two previously restored, urban-suburban streams in Reston, Virginia – Snakeden Branch and The Glade. The aquatic benthic macroinvertebrate, fish...
Raster and vector geospatial data of interpolated groundwater level altitude associated with a groundwater-level map of Fauquier County, Virginia, October - November 2018 Raster and vector geospatial data of interpolated groundwater level altitude associated with a groundwater-level map of Fauquier County, Virginia, October - November 2018
This dataset is the product of a geospatial interpolation using groundwater-level data obtained from a U.S. Geological Survey (USGS) synoptic survey of 129 groundwater wells in Fauquier County, VA from October 29 through November 2, 2018 and selected points from the National Hydrography Dataset (NHD). Methodology is detailed in USGS SIR 2022-5014 "Groundwater-level contour map of...
