NYSDEC Water Quality Classifications - Stream/Rivers [NYS.WTRCLS_LINE]
Dataset Identification:
Resource Abstract:
This data set provides the water quality classifications of New York State's lakes, rivers, streams and ponds, collectively
referred to as water bodies. All water bodies in the state are provided a water quality classification based on existing,
or expected best usage, of each water body or water body segment. Under New York State's Environmental Conservation Law (ECL),
Title 5 of Article 15, certain waters of the state are protected on the basis of their classification. Streams and small water
bodies located in the course of a stream that are designated as C (T) or higher (i.e., C (TS), B, or A) are collectively referred
to as "protected streams."

State laws contain mandates to protect the public health and safety. NYSDEC implements and enforces these legislative mandates,
which are the fundamental source of the department's powers. Regulations are drafted by experts in environmental or natural
resource fields, with input from the regulated community and the general public. NYSDEC presents all proposed regulations
for public comment, a process that often includes public hearings. After revisions in response to the comments, the regulations
are officially promulgated and their provisions acquire the force of law.

Additional information on resource:
1. These digital water quality classifications are an unofficial version of the State's water quality classifications. For
the official version please refer to Title 6 of the Official Compilation of Codes, Rules and Regulations of the State of New
York (6NYCRR) Part 800 et seq. ( http://www.dec.ny.gov/regulations/regulations.html ). The water quality classifications have
been developed by the Department of Environmental Conservation, Division of Water from the most current sources available.
Where there were inconsistencies in the maps the most current representation has been used. These data have not been submitted
to the Department of State and they are not official classifications. However, they are largely consistent with the official
regulations. Therefore, the public should not make any business decisions and/or financial commitments based on the water
quality classification data until they have secured the necessary permissions from the Department of Environmental Conservation.
2. Water bodies that are not represented in this data set always have classifications unless they are excluded from classification
in 6NYCRR, usually because they are located in a forest preserve. Please refer to the "Special Conditions" in 6NYCRR Chapter
X (parts 800-941) for specific information. In MOST cases, the following will apply: water bodies that are not represented
in this data set and have flow all year (perennial flow) have the classification of the water body they flow into; water bodies
that are not represented in this data set and have flow only seasonally (intermittent flow) have a classification of "D."
Since it may be difficult to determine if a water body has perennial or intermittent flow, please contact your DEC Regional
Office if there is any doubt. DEC has the final authority to determine if a waterbody has perennial or intermittent flow.
3. For additional information about NYSDEC's Water Quality Classification program, please see the Water Quality Standards
and Classifications page on the NYSDEC web site ( http://www.dec.ny.gov/chemical/23853.html ). 4. This data set should be
used to identify water quality classifications only; it is not a complete representation of water bodies. The USGS high-resolution
National Hydrography Dataset (NHD) should be used along with this data set to see a more complete representation of water
bodies (see http://nhd.usgs.gov ). 5. This data set includes a line and a polygon layer. Most water bodies, including most
lakes and ponds along the stream network, are represented in the line layer. Lakes and ponds along the stream network are
represented by flow lines (sometimes called centerlines) drawn through lakes and ponds to connect flow in a linear network.
Isolated lakes and ponds, and other features difficult to represent with flow lines (such as coastal waters), are represented
in the polygon layer. The NHD should be used along with this data set to see the polygons for lakes, ponds and large streams.
6. Water body features (lines and polygons) are based on the NHD whenever possible. Where water body features are not found
in the NHD, or are significantly different than described by 6NYCRR and associated maps, they were digitized using visual
estimation based on information from 6NYCRR and associated maps. 7. In some instances this data set may indicate assignment
of classifications for waters contained within the boundaries of the State-owned forest preserve lands and, therefore, controlled
under the provisions of the State Constitution and the Conservation Law. Such waters are excluded from classification to the
extent that any part of such waters may be located within the boundaries of the State-owned forest preserve lands. All waters
within 100 feet of the boundaries of the State-owned forest preserve lands shall be assigned to class A with standards of
quality and purity for class A.
