Discrete chloride and specific conductance (SC) measurements, chloride-SC regression equations, and daily and hourly mean SC values and chloride predictions for 88 USGS water quality monitoring stations in the Delaware River Basin, 2019-2022 Discrete chloride and specific conductance (SC) measurements, chloride-SC regression equations, and daily and hourly mean SC values and chloride predictions for 88 USGS water quality monitoring stations in the Delaware River Basin, 2019-2022
Freshwater salinization, or the increase of dissolved ions like chloride, threaten freshwater streams and rivers across the globe. Continuous (e.g., daily or hourly mean) predictions of chloride concentration were used in an analysis to quantify the extent to which chloride concentrations exceeded ecological thresholds at U.S. Geological Survey (USGS) water quality monitoring sites...
Positive openness for the Delaware River Basin Positive openness for the Delaware River Basin
In support of the U.S. Geological Survey Water Mission Area’s assessment of Integrated Water Science (IWS) basins across the United States (Van Metre and others, 2020), this data release contains a positive openness raster dataset that was developed for the Delaware River Basin. The raster was developed to help characterize the landscape and channel features within the Delaware River...
Georgia active streamgages with attributes and their upstream drainage basins, 2024 Georgia active streamgages with attributes and their upstream drainage basins, 2024
In cooperation with the Georgia Department of Transportation, the U.S. Geological Survey (USGS) has prepared geospatial layers representing the locations of USGS streamgages, other weather monitoring locations, and upstream drainage basins of streamgages in the State of Georgia. These layers also include streamgages in nearby states which directly measure waters within Georgia. The...
Local and Global Geodatabases Used in South Carolina StreamStats 2024 Local and Global Geodatabases Used in South Carolina StreamStats 2024
In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey (USGS) updated the foundational geospatial layers for the South Carolina StreamStats web application (https://www.usgs.gov/streamstats), which provides analytical tools useful for water-resources planning and management (Kolb and others, 2018). This dataset comprises the 45 local geodatabases...
Stream stage, stream temperature, and climate metrics for 30 streams spanning land use and management gradients in the Delmarva Peninsula of Delaware, Maryland, and Virginia, 2022 Stream stage, stream temperature, and climate metrics for 30 streams spanning land use and management gradients in the Delmarva Peninsula of Delaware, Maryland, and Virginia, 2022
This data release contains summary metrics describing stream stage, stream water temperature, and short-term climate conditions (daily precipitation and air temperature) for 30 streams spanning gradients of forest and row-crop land uses and agricultural best management practice implementation in the Delmarva Peninsula of Delaware, Maryland, and Virginia, USA. This setting is the second...
Autonomous Underwater Vehicle Water-Quality Measurements in the Cape Fear River, multiple locations, North Carolina, 2022 Autonomous Underwater Vehicle Water-Quality Measurements in the Cape Fear River, multiple locations, North Carolina, 2022
This U.S. Geological Survey (USGS) data release presents water-quality and bathymetric data measured with an Autonomous Underwater Vehicle (AUV) during spatial surveys in the Cape Fear River near Lock and Dam 1 near Riegelwood, NC and at the confluence of the Haw and Deep Rivers near Moncure, NC in 2022. The Cape Fear River Basin is contained entirely within North Carolina and has a...
Predictions of specific conductance and departures from background specific conductance in the Chesapeake Bay watershed, 2001-2016 Predictions of specific conductance and departures from background specific conductance in the Chesapeake Bay watershed, 2001-2016
Freshwater salinization is an emerging water quality issue for non-tidal streams and rivers in the Chesapeake Bay watershed (CBW), USA region. A model was developed to predict specific conductance (SC; a proxy for salinity) conditions across the CBW and departures from background SC. Discrete observations of SC from 1999-2016 were acquired from a published SC data inventory and...
Topographic datasets compiled for the Lower Roanoke River corridor in 2003, 2014, and 2020, North Carolina Topographic datasets compiled for the Lower Roanoke River corridor in 2003, 2014, and 2020, North Carolina
This data release contains topographic information compiled for the Lower Roanoke River corridor located in eastern North Carolina. The Lower Roanoke River corridor includes the mainstem of the Roanoke River from Roanoke Rapids, NC (below the Roanoke Rapids dam) to the mouth of the Roanoke River at its confluence with the Albemarle Sound, and the associated floodplains and wetland areas...
Landscape characteristics for urban gradients in United States cities across multiple scales Landscape characteristics for urban gradients in United States cities across multiple scales
This dataset contains tabular data at three scales (city, tract, and synoptic site) and related vector shapefiles (for watersheds or buffers around synoptic sites) for areas included in the Carbon in Urban River Biogeochemistry Project (CURB) to assess how social, built, and biophysical factors shape aquatic functions. The city scale included 486 urban areas in the continental United...
Datasets for Assessment of Nutrient Load Estimation Approaches for Small Urban Streams in Durham, North Carolina, 2009-2020 Datasets for Assessment of Nutrient Load Estimation Approaches for Small Urban Streams in Durham, North Carolina, 2009-2020
In cooperation with the City of Durham Public Works Department Stormwater Division, the U.S. Geological Survey (USGS) conducted a study to evaluate whether alternate monitoring strategies that incorporated samples collected across an increased range of streamflows would improve nutrient load estimates for Ellerbe and Sandy Creeks, two small, highly urbanized streams in the City of Durham...
Streambank topographic lidar survey of the French Broad River near the Interstate 26 bridge located south of Asheville, NC – December 2021, Mid-construction #2 Streambank topographic lidar survey of the French Broad River near the Interstate 26 bridge located south of Asheville, NC – December 2021, Mid-construction #2
In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S Geological Survey (USGS) in cooperation with the NCDOT conducted a pre-construction light detection and ranging (lidar) survey of the streambanks...
