Drainage network for the Greater Raleigh Area, North Carolina, 2015-2022

As part of a collaborative study with the City of Raleigh, North Carolina, the U.S. Geological Survey developed a drainage network for the Greater Raleigh Area, North Carolina using the most recent available lidar data, representing the years 2015 and 2022. This dataset includes the delineated drainage network ( and rasters representing the breached and filled digital elevatio

Associated Data for the Phytoplankton, Taste-and-Odor Compounds, and Cyanotoxin Occurrence in Drinking Water Supply Reservoirs in the Triangle Area of North Carolina

As part of the Triangle Area Water Supply Monitoring Project, the U.S. Geological Survey conducted a study to evaluate the occurrence and distribution of phytoplankton, taste-and-odor compounds, and cyanotoxin occurrence in four water-supply reservoirs in the Triangle area of North Carolina. This data release contains the associated data described in the Scientific Investigations Report, "Phytopla

Foundational Geospatial Layers for South Carolina StreamStats 2024

In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey updated the foundational geospatial layers for the South Carolina StreamStats web application (, which provides analytical tools useful for water-resources planning and management (Kolb and others, 2018). This dataset presents the digital elevation model, lidar-de

Associated data for the Triangle Area Water Supply Monitoring Project, North Carolina, October 2019 - September 2022

The U.S. Geological Survey and a consortium of local governments in North Carolina have partnered together to track water quality and quantity conditions in several of the area’s water-supply reservoirs and streams, known as the Triangle Area Water Supply Monitoring Project (TAWSMP). This data release contains the associated data described in the Open-File Report, "Triangle Area Water Supply Monit

MODFLOW-2000 data sets used in two predictive scenarios of groundwater flow and pumping (1900-2050) near Mount Pleasant, South Carolina

An existing three-dimensional model (MODFLOW-2000) by Fine, Petkewich, and Campbell (2017) ( was slightly updated to evaluate two water-management scenarios and predict the effects of increased pumpage on the groundwater flow and groundwater-level conditions in the Mount Pleasant, South Carolina area. This model was originally developed in 2007, by Petkewich and

Autonomous Underwater Vehicle Water-Quality Measurements in the Cape Fear River, multiple locations, North Carolina, 2020-2021

The Cape Fear River Basin was added to a nationwide program called The Sustainable Rivers Program (SRP) in 2016. SRP is a joint program between The Nature Conservancy (TNC) and the Army Corps of Engineers (Corps) to improve the health of rivers by analyzing how the Corps operates their infrastructure, such as the release of water out of dams. The SRP attempts to analyze the effects from dams and u

Streambank topographic lidar survey of the French Broad River near the Interstate 26 bridge located south of Asheville, NC – November 2019, Pre-construction

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 streambank light detection and ranging (lidar) survey of the streambanks of the French B

Target-Chemical Concentrations for Assessment of Mixed-Organic/Inorganic Chemical and Biological Exposures in Private-Well Tapwater at Campbell, Wisconsin, 2021

Tapwater samples were obtained from groundwater sources on French Island, in the town of Campbell, Wisconsin. Samples from three locations were collected multiple times over a period of three days to assess temporal variations in water quality. Samples from an additional eight locations, were collected one time, spatially distributed around Campbell. Due to privacy concerns, the exact location of

Estimate of Georgia water-use data by county for 2020

In cooperation with the Georgia Environmental Protection Division, the U.S. Geological Survey compiled four datasets summarizing 2020 water use for the state of Georgia by county. These datasets include: annual aquifer withdrawals; industrial water use by category; public supply water use; and total water use across multiple variables, including domestic, commercial, industrial, mining, thermoelec

Stream stage, stream temperature, and climate metrics for 30 streams spanning land use and management gradients in the Shenandoah Valley region of West Virginia and Virginia, 2021

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 pasture land uses and agricultural best management practice implementation in the Shenandoah Valley region of Virginia and West Virginia, USA. This setting is the first of four setti

Land Cover Basin Characteristics Rasters from NLCD 2019 for South Carolina StreamStats

In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey calculated four land cover basin characteristics rasters from the National Land Cover Database (NLCD) 2019 as part of updating the South Carolina StreamStats application. These datasets are raster representations of impervious surface, developed, forested, and storage land cover attributes within the So

Application of the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System (NHM-PRMS),1980-2016, Daymet Version 3 calibration

This data release contains inputs and outputs for hydrologic simulations of the conterminous United States (CONUS) using the National Hydrologic Model (NHM) application of the Precipitation Runoff Modeling System (PRMS) in ASCII and binary format and explanatory graphics in pdf format. These simulations were developed to provide estimates of water availability for historical conditions for the per
