This feature layer displays the protected and critical areas of water supply watersheds as designated by NC DEQ Division of Water Resources. This data was uploaded in November 2014. Additional information about water supply watersheds and how these areas are classified and the rules that accompany these classifications, can be found on the NC DEQ-DWR Classifications and Standards website.This feature layer can be found in the NC Surface Water Classification map application.

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).

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.

Wake County is split between two River Basins (6-digit Hydrologic Unit Code), the Cape Fear River Basin and Neuse River Basins. River basins are determined by the US Geological Survey (USGS). USGS delineates drainage areas at 6 different levels all nesting within each other. These levels start at a regional scale and are given a 2-digit Hydrologic Unit Code (HUC). Two digits are added to the code at each level as it progresses to a smaller drainage area. River basins are at the third level and designated with a 6-digit HUC. Additional information about USGS's WDB can be found at this link.If you would like to find out more about River Basins across the state of NC, visit the Find Your HUC website.

This web site contains the Federal Geographic Data Committee-compliant metadata (documentation) for digital data produced for the North Carolina, Department of Environment and Natural Resources, Public Water Supply Section, Source Water Assessment Program. The metadata are for 11 individual Geographic Information System data sets. An overlay and indexing method was used with the data to derive a rating for unsaturated zone and watershed characteristics for use by the State of North Carolina in assessing more than 11,000 public water-supply wells and approximately 245 public surface-water intakes for susceptibility to contamination. For ground-water supplies, the digital data sets used in the assessment included unsaturated zone rating, vertical series hydraulic conductance, land-surface slope, and land cover. For assessment of public surface-water intakes, the data sets included watershed characteristics rating, average annual precipitation, land-surface slope, land cover, and ground-water contribution. Documentation for the land-use data set applies to both the unsaturated zone and watershed characteristics ratings. Documentation for the estimated depth-to-water map used in the calculation of the vertical series hydraulic conductance also is included.

A NatureNet project was initiated in 2018 in by The Center for Biodiversity Outcomes and The Nature Conservancy to identify solutions for water quality management under extremes ranging from floods to droughts with a focus on agroecosystems. Hurricanes that damage lives and property are accompanied by poor water quality that affects both human and natural communities, yet these water quality impacts are difficult to quantify. To aid in understanding the implications of elevated storm frequency and intensity, we developed an operational remote sensing-based hurricane flood extent mapping method, analyzed potential impacts to human and natural assets from Hurricane Matthew (2016) and Hurricane Florence (2018) in North Carolina, and identified options that could reduce impacts and increase resilience to future storms. Flooding detected with synthetic aperture radar (>91% accuracy) extended beyond state-mapped hazard zones. This data package provides the training datasets and flood map products for Hurricanes Matthew and Florence, as well as a map of opportunities where watershed-scale interventions could be implemented in flooded areas across the Piedmont and Coastal Plain. Accompanying code is available as supporting information for the peer-reviewed publication, and can also be accessed from https://github.com/dschaffersmith/repeatFloodingNC. The methods for these and other analyses are also described in greater detail in: Schaffer-Smith, D., Myint, S.W., Muenich, R.L., Tong, D., & DeMeester, J.E. 2020.

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...
