The major river basin lines in NC are drawn based on the nationally recognized hydrologic unit codes (6-digits). Some basins have been split apart due to previously written general statutes. This feature service was uploaded in December 2014. This feature layer can be found in the NC Surface Water Classification map application.

The North Carolina Department of Environment, Health, and Natural Resources, Division of Environmental Management, in cooperation with the NC Center for Geographic Information and Analysis, developed the digital Water Supply Watersheds data to enhance planning, siting and impact analysis in areas directly affecting water supply intakes. This file outlines the extent of protected and critical areas and stream classifications for areas around water supply watersheds in which development directly affects a water supply intake. This file enables users to identify the areas which have special restrictions for building and development based on water supply intakes. This file is updated as changes occur.

This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).

The Pee Dee and Cape Fear River Basins in North Carolina and South Carolina were chosen as a focus area study (FAS) for the U.S. Geological Survey (USGS) National Water Census (NWC) in 2016. The objective of the NWC is to place technical information and tools in the hands of stake holders so that they can make decisions on water availability. The USGS South Atlantic Water Science Center, comprised of North Carolina, South Carolina, and Georgia, conducted a 3-year study of water use and availability to provide information related to the competing societal and ecological water needs in the Southeastern Atlantic Coastal Basins of the Carolinas. One task to meet this objective was compiling water withdrawal and return data by category from local, regional, and state-scale data sources so that those data could be utilized in surface-water models, a groundwater model, an ecological flow model, and for predictions of future water needs. This dataset presents wastewater-return estimates from years 2000, 2005, 2010, and 2015 which are aggregated to the Soil and Water Assessment Tool (SWAT) model catchment-area level developed for the Pee Dee and Cape Fear River Basins.

This airborne LiDAR terrain mapping data was acquired January through March 2001. The data were collected for the floodplain mapping program for the state of North Carolina. The data were collected for the state in three phases: 1, 2, and 3. This metadata record describes that data that were in phase 1 of collection and fall within the Neuse, Pasquotank, Tar-Pamlico, and White Oak River Basins...

The Cape Fear and Pee Dee River Basins in North Carolina and South Carolina were chosen as a focus area study (FAS) for the U.S. Geological Survey (USGS) National Water Census (NWC) in 2016. The objective of the NWC is to place technical information and tools in the hands of stake holders so that they can make decisions on water availability. The USGS South Atlantic Water Science Center, comprised of North Carolina, South Carolina, and Georgia, conducted a 3-year study of water use and availability to provide information related to the competing societal and ecological water needs in the Southeastern Atlantic Coastal Basins of the Carolinas. The Coastal Carolinas study area includes the Pee Dee and Cape Fear River Basins and the Atlantic Coastal Plain from Brunswick, Georgia, to near Greenville, North Carolina. The study is divided into 5 main components: 1) Societal Water-Use Data Compilation and Refinement, 2) Land-Use, Population, Water-Use and Climate Change Scenarios, 3) Surface-Water Modeling, 4) Ecological Response Modeling, and 5) Groundwater Modeling. One task to meet this objective was to compile water withdrawal and return data by water-use category from local, regional, and state-scale data sources in order to utilize those data in surface-water models, a groundwater model, an ecological flow model, and for predictions of future water needs. This data release contains (1) Groundwater withdrawals for Georgia, South Carolina, and North Carolina aggregated by groundwater MODFLOW model cell area, year, and water-use category; (2) Surface-water withdrawal estimates for years 1983 – 2017 aggregated to the Soil and Water Assessment (SWAT) model catchment level developed for the Pee Dee and Cape Fear River Basins; (3) Wastewater return estimates from years 2000, 2005, 2010, and 2015 aggregated to the Soil and Water Assessment (SWAT) model catchment level developed for the Pee Dee and Cape Fear River Basins; and (4) Surface-water and groundwater off-stream water-use estimates in the Coastal Carolinas study area for selected water-use categories from years 2000, 2005, 2010, and 2015 aggregated to the 8-digit (subbasin) hydrologic unit level within state boundaries in the Coastal Carolinas study area.

This shapefile contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the state of South Carolina. This dataset is the result of clipping the feature class 'NFHAP 2010 HCI Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the state boundary of South Carolina. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites. The source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units. In this data set, these variables are linked to the catchments of the National Hydrography Dataset Plus Version 1 (NHDPlusV1) using the COMID identifier. They can also be linked to the reaches of the NHDPlusV1 using the COMID identifier. Catchment attributes are available for both local catchments (defined as the land area draining directly to a reach; attributes begin with "L_" prefix) and network catchments (defined by all upstream contributing catchments to the reach's outlet, including the reach's own local catchment; attributes begin with "N_" prefix). This shapefile also includes habitat condition scores created based on responsiveness of biological metrics to anthropogenic landscape disturbances throughout ecoregions. Separate scores were created by considering disturbances within local catchments, network catchments, and a cumulative score that accounted for the most limiting disturbance operating on a given biological metric in either local or network catchments. This assessment only scored reaches representing streams and rivers (see the process section for more details). Please use the following citation: Esselman, P., D.M. Infante, L. Wang, W. Taylor, W.

The latest 12-Digit HUC boundaries, along with the calculated US Census population within each subwatershed area. HUC boundaries are from the USGS National Hydrography Watershed Boundary Dataset. US Census 2020, 2010, and 2000 Block Data was acquired through NC OneMap.Subwatershed population estimates were derived from the 2020, 2010, and 2000 Block population data from the US Census. The ArcGIS Tool "Summarize Within" was used to calculate the total population within each subwatershed for each census period. As census blocks and subwatershed boundaries do not always coincide, the calculated population is only an estimate and is not to be used as an exact figure.

Baseflow grab samples and flow measurements were collected bi-weekly from 27 urbanized catchments in the NC piedmont over periods of one to fours years between Fall 2013 and Fall 2019. A subset of 13 catchments were sampled for isotopic nitrate in 2018. Sampled catchments were selected to approximate the median and span most of the range in metrics of landcover, infrastructure, and population density for developed NHD+ catchments in the Haw and Upper Neuse River basins. Land cover, infrastructure, topography, geology, and hydrogeomorphic position of development features were characterized for the study area. This data supports the findings of the manuscript "The sources and transport of baseflow N loading across a developed rural-urban gradient" submitted to WRR for review in Nov. 2021.
