Description:
Abstract: This shapefile contains the boundaries of the 8-digit watersheds
that intersect New York State.
Purpose: These hydrologic unit boundaries provide a uniquely identified
and uniform method of subdividing the state into large drainage areas at
1:250,000 scale.
Supplemental_Information: The 8-digit hydrologic unit codes for each watershed indicate the
hydrologic region (first two digits), hydrologic subregion (second two
digits), accounting unit (third two digits), and cataloging unit (fourth
two digits), as defined by the USGS. This dataset was extracted from the
national 1:250,000-scale dataset that is available on the USGS Water
Resources website:
