**Uploaded to SDE on 11/18/10 by Malinda Ford.** The North Carolina Center for Geographic Information and Analysis, in cooperation with the North Carolina Division of Water Quality, developed this digital hydrography dataset with
Use Support information and water quality classifications to enhance planning, siting and impact analysis. This file enable users to identify surface water features
which have special restrictions for building and development based on the locations of the features and their water quality classifications.
Surface waters consist of streams, rivers, lakes, ponds, reservoirs, and shorelines. This file also enables users to determine whether a particular surface water is meeting its intended water quality uses. The linework is based on the USGS 1:24,000-scale
Digital Line Graphs but has had additions from other sources as needed to include the hydrographic features in the stream classification codes.
The data are updated as changes occur.
This dataset was created to provide a large and diverse group of users a data resource of North Carolina surface waters to enhance planning for sustainable growth and assist governmental
agencies in making resource management decisions through use of a Geographic Information System (GIS).
Post DLG and data refinements include:
a) Translation of DLG to ARC/INFO data format
b) Review and correction for incompleteness and/or incorrect
DLG attributes
c) Internal and external (in-progress) coordinate edgematching
of features along map edges
d) Addition of hydrographic features as required by DWQ for
stream classifications
e) Addition of hydrographic attributes as identified in attribute
table specifications
Use support for the basin will be updated on a 5-year schedule concurrent with the North Carolina Division of Water Quality basinwide planning schedule.
Stream classification information will be updated as changes occur.

All attribute codes have been reviewed for accuracy by the associated agency. NCDENR, Division of Water Quality is responsible for stream classifications and use
support. The NC Center for Geographic Information and Analysis is responsible for linework and DLG codes.
Software checks for topology. There are no duplicate features, but coincident lines are maintained between data layers where appropriate.
Polygonal features begin and end at the same point, contain no overshoots or undershoots. Linear features are continuous where appropriate, i.e., dangling arcs are removed if they are not required.
These data represent the locations and identities of surface shorelines, waters consisting of streams and rivers, lakes, ponds, and as depicted on USGS 1:24,000-scale digital line graphs
and supplemented to reflect hydrographic features classified by the state but not represented on the original DLG linework. Each stream reach is labeled with stream classification and use support information.
Hydrography 1:24,000-scale features were taken from the USGS 1:24,000-scale DLGs. Supplemented hydrographic features were digitized from 1:100,000-scale bases and the linework checked
against the bases to within a linewidth.

The statewide 1:24,000 hydrography tiles were edgematched and mapjoined. The neatlines and extraneous labels points were removed. The coverages
were clipped to the North Carolina river basin boundaries derived from the HUNCRB data layer. Each river basin was edited such that index numbers matched their corresponding stream reach. Attributes
were re-named and edited in cooperation with the Division of Water quality. CGIA and DWQ updates the digital files as needed.

Water quality for specific stream reaches were assessed by DWQ and a use support ratings assigned. This rating identifies
how well a stream reach meets its designated uses. Ratings and additional attributes are maintained in an ACCESS database and updated by river basin on a 5-year rotation. The
Division of Water Quality joins these data to the 24k hydrography data layer. DWQ provides CGIA with updates as they occur either from a new assessment, reclassification or correction.
