Project study area (polygon) for the Arizona Apache-Sitgreaves National
Forest with six HUC5 study watersheds. Note this dataset includes the
six (6) watersheds and supercedes the dataset with three (3) watersheds (http://app.databasin.org/app/pages/datasetPage.jsp?id=4d93a76be66543169c46365d08dd5283).
Original Description:
A data set describing the 2-dimensional spatial location of
hierarchical hydrologic unit delineations based on Natural Resource
Conservation Service and U.S. Geological Survey approved subbasins
within or partially within a Forest Service administrative unit.
Multiple subbasins are typically managed in a single data set for a
Forest or administrative unit.
This data is a set of merged datasets for the Southwest Region.
There is a complete digital hydrologic unit boundary layer to the
Subwatershed (12-digit) 6th level for the states of New Mexico, Oklahoma,
Arizona, and Texas. This data set consists of geo-referenced
digital data and associated attributes created in accordance with the
"FGDC Proposal, Version 1.0 - Federal Standards For Delineation of
Hydrologic Unit Boundaries 3/01/02"
(http://www.ftw.nrcs.usda.gov/huc_data.html).

The distributor shall not be held liable for improper or incorrect
use of this data, based on the description of appropriate/inappropriate uses
described in this metadata document. It is strongly recommended that this data is
directly acquired from the distributor and not indirectly through other sources
which may have changed the data in some way. These data should not be used at scales
greater than 1:24,000 for the purpose of identifying hydrographic watershed boundary
feature locations. United States Department of Agriculture-Natural Resources
Conservation Service should be acknowledged as the data source in products derived
from these data. The Watershed Boundary Dataset is public information and may be
interpreted by all organizations, agencies, units of government, or others based on needs;
however, they are responsible for the appropriate application of the data. Federal,
State, or local regulatory bodies are not to reassign to the Natural Resources
Conservation Service any authority for the decisions they make. The Natural Resources
Conservation Service will not perform any evaluations of these maps or purposes related
solely to State or local regulatory programs. Photographic or digital enlargement of
these maps to scales greater than that at which they were originally delineated can
result in misrepresentation of the data. If enlarged, the maps will not include the
fine detail that would be appropriate for mapping at the small scale. Digital data
files are periodically updated. Files are dated, and users are responsible for
obtaining the latest version of the data from the source distributor.
