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

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The NC DEHNR-DEM delineated the boundaries on 24k USGS paper topographic maps. NCCGIA digitized these boundaries and attributed them with DEM classification information, river basin and stream names, and acres per polygon. The digital files were plotted and overlayed to the originals and linework and label corrections were made. This digital file is updated as changes occur.
Logical_Consistency_Report:
Using ESRI's ARC/INFO GIS software, the dataset was built for arc and polygon topology using the "build" command. The data set was then cleaned with a fuzzy tolerance of 1 foot. Topology has not been edited since the last build or clean.
Completeness_Report:
These data represent the locations and identities of Water Supply Watersheds in North Carolina as mapped by the NCDEM. Each watershed is labeled with either a protected or critical area classification. All boundaries are approved by DEM whether they are the original DEM boundaries or changes to original boundaries submitted for revision by local or county governments.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Water supply watershed boundaries were marked on 7.5 Minute USGS paper topographic maps which meet National Map Accuracy Standards, using a best estimate with reference to surrounding features. Ridge lines were interpolated from contours by cartographers and reviewed by DEM staff. Counties and municipalities have restudied certain boundaries in detail for adjustment by DEM. Boundaries drawn were digitized and check plots used to ensure correct boundary location, within a line width. map units: feet, precision: single, fuzzy: 1.0, dangle: 10.0

Process_Description:
Water supply watershed boundaries were delineated by cartographers interpolating ridgelines on paper USGS 7.5 minute topographic maps. Boundaries were delineated around known water supply intakes. Intakes on streams or rivers had critical areas delineated as ridgelines or half mile buffers, whichever was closest, upstream of the intake location. Protected areas were delineated with ridgelines or ten mile buffers, which ever was closer. For intakes on lakes and reservoirs, buffers were delineated from the apparent pool elevation of the water body as shown on the USGS quadrangle using the same limits as above. Boundaries were reviewed by DEM staff. After the linework was digitized by NCCGIA (see below), DEM staff reviewed the linework and attributes for accuracy. DEM supplies CGIA with updates as they occur.

Process_Description:
Water supply watersheds were digitized from hand delineated water supply watershed boundaries on USGS 7.5 Minute series paper basemaps. The digital files were attributed and checkplots were created for review by the Water Quality Section. Necessary corrections were made and new plots were run. Post processing involved edgematching and mapjoining of USGS 7.5 Minute series maps used to create the digitized data. This process generated one statewide polygon coverage. Boundaries of the watersheds throughout the state, in an effort to have them coincident with the Hydrologic Units adopted earlier by EHNR-DEM and USDA-NRCS, were replaced with the hydrologic units Boundaries for the watersheds. Boundaries coincident in both coverages were deleted from the watershed file and copied back from the hydrologic units file. CGIA updates the digital file as needed.

Entity_and_Attribute_Overview:
A polygon coverage depicting areas classified by the Division of Environmental Management as having either protected or critical water supply watershed areas. The polygon attribute table (PAT) has attribute data including total area in coverage units (square feet), total perimeter (linear feet), polygon internal identification number, polygon user identification number, a DEM internal index number that relates to the identification of the stream which runs through the watershed, the classification of the watershed, the river basin the watershed is contained in, the name of the stream which runs through the watershed, the classification date of the watershed, the DEM internal grid number that relates to the 7.5 minute USGS topographic map, the type of watershed -whether (P)roposed or (C)ritical, and the number of acres per polygon. There are no look up tables, annotation or cartosets for this data. A deductive estimate was used to determine the attribute accuracy value. The value domains used are as follows: High - greater than 90% reliability; Medium - greater than 75% reliability; Low - less than 75% reliability.
