Abstract:
The USDA-Natural Resources Conservation Service, Raleigh Office in
cooperation with the NC Center for Geographic Information & Analysis, and
the NC Dept. of Environment, Health and Natural Resources, Division of
Water Quality developed the Hydrologic Units-North Carolina digital data
to track resource and conservation activities in the state's river basins
and subbasins. Using the 14-digit hyrologic unit code the regional,
subregional, accounting, cataloging, NRCS sub-unit, and NRCS reporting
unit boundaries id's are recorded.  The area attributes allow the user
to see hydrologic unit, river basin and subbasin levels of geography.
This file specifically shows the North Carolina subbasins.
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 from the protected and critical watersheds layer for the
state was used during the development of the HU boundaries.
This coverage supersedes data on past versions, particularly
the cama24.hu coverage, which was completed as a preliminary
to this statewide version.  Some boundaries may have changed
between the two versions.
There are two additional coverages which were generated from
this data, the huncrb-river basins; and huncsb-subbasins files.
See the cross references section for details.

The following is an excerpt from the "North Carolina Hydrologic
Unit River Basin Study," USDA, Natural Resources Conservation
Service, November 1995.
Under the sponsorship of the Water Resources Council,
a nationally uniform hydrologic unit system was developed in
1974 by the US Geological Survey's Office of Water Data
Coordination. This system divides the country into 21 regions,
222 subregions, 352 accounting units, and 2,149 cataloging units,
based on surface hydrologic features.  A hierarchical code
consisting of two digits for each of the above four levels
combine to form an eight-digit hydrologic unit. The hydrologic unit
system is used to identify any hydrologic area of interest.  An
eight-digit hydrologic unit generally covers 700 or more square
miles.
In 1978, the USDA-Natural Resources Conservation Service (NRCS)
issued a policy that all resource inventories and surveys were
to be coded with and capable of being retrieved by hydrologic
unit codes (HUCs).  At about the same time, NRCS initiated a
national program to further subdivide HUCs into watershed-sized
areas (nominally 250,000 acres, or 390 square miles) for use in
water resource planning.  An extension of three digits was added
to the eight-digit HUC to designate sub-watersheds, thus forming
elevin-digit HUCs.
This 1995 Hydrologic Unit (HU) Study divides the state river basins
and subbasins into smaller fourteen-digit hydrologic units
that will be useful in targeting project activities, resource
inventories, and reporting conservation activities. These
fourteen-digit hydrologic units of approximately 4,000 acres
(6 sqare miles) to 50,000 acres (78 square miles) are small enough
in size to be useful as a planning and reporting tool for the
USDA-Natural Resources Conservation Service (NRCS) and other
government and state agencies.
This 1995 fourteen-digit HU map will replace the 1974 eight-
digit HU map [U.S. Water Resource Council (WRC)] and the 1978
NRCS eleven-digit HU map as the locating tool for planning in
NRCS.  The 1995 HU map were produced using 7.5 minute USGS
quadrangle base maps (1:24,000 scale).

NOTE: The subbasin 6-digit code (SUBBASIN#) was developed independently
from the hydrologic unit codes, from an entirely different numbering
system.  (Example of code: 03-03-01.)  The first two numbers identify the
river basin designations adopted by the Environmental Protection Agency.
(Date of source: 1974.)  Subbasin boundaries were added within individual
river basin boundaries (by the office that is now known as the Division
of Water Quality, Water Quality Planning Section).  Sequential numbers
(example -01) were added by DWQ to the first four-digit EPA code to give
each subbasin a unique six-digit identifier.  (Each subbasin incorporates
three or more hydrologic units.  The subbasin boundaries have been
modified to be coincident with the hydrologic unit boundaries.)
Contact Alan Clark at DWQ for more information on the subbasin# code
(733-5083, extension 570).

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The USDA-Natural Resources Conservation Service delineated the
hydrologic units for North Carolina on 24k USGS topographic maps.
These boundaries were attributed with USDA-NRCS classification
information, acres per polygon, and square miles per polygon.
The digital files were plotted and overlayed to the originals and
linework and label corrections were made. Once complete
and under the direction of DENR-DWQ, the digital file was further
defined by subbasins derived from HUs and the river basins derived by
subbasins. Appropiate ids were added to the attribute files. Attribute
accuracy is considered high. There are no lookup tables, annotation or
cartosets for this data.
Logical_Consistency_Report:
Using ESRI's ARC/INFO GIS software, the data set 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 depict the boundaries and unit numbers from the
USDA-NRCS Hydrologic Unit River Basin Study, 1995. The study
divides the state river basins into subbasins used to track
resource and conservation activities.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Hydrologic Units for North Carolina were delineated on 7.5 Minute
USGS paper topographic maps which meet National Map Accuracy Standards,
using a best estimate with reference to surrounding features.
Boundaries drawn were digitized and checkplots were used to ensure
correct boundary location, within a line-width. map units: meters,
precision: single,   fuzzy: 1.0,  dangle: 10.0.

Paper maps used to delineate the hydrologic units
Process_Step:
Process_Description:
Hydrologic Units were delineated on USGS 1:24,000 paper topographic
maps by following contour lines.  HU codes were written onto the
topo maps for later attribute coding.  All topo maps within the Coastal
Area Management Act (CAMA) area were given to CGIA for digitization.
All other topos across the state were given to Westinghouse-Landmark
GIS, Inc. for digitization. The USDA-Natural Resources Conservation
Service delineated the hydrologic units for North Carolina on 24k
USGS topographic maps.  The digital files were plotted by CGIA and
overlayed to the originals and reviewed by staff at NRCS and DENR-DWQ.
Needed corrections were made. Once an agreed upon, digital file was
created.  DWQ assisted NRCS in modifying certain boundaries which were
not at the time coincident with the subbasins that DWQ manages.
After that was completed, NRCS met with officials from neighboring states
(Virginia, South Carolina, Georgia, and Tennessee) to edgematch the
Hydrologic Unit boundaries across the state line. This was done to the
11-digit boundary, not the 14-digit.  Once this file was complete, DWQ
assisted CGIA in establishing new subbasin boundaries derived from HU
boundaries, and then established new river basin boundaries derived
from subbasin boundaries.  This digital file is updated as changes occur.

Hydrologic units were digitized from hand delineated boundaries on
USGS 7.5 Minute series paper base maps.  The digital files were
attributed and checkplots were created for review by the Natural
Resources Conservation Service and the NC Division of Water Quality.
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.  CGIA updates the digital
file as needed.
