Sec. 885.3. Definitions

The several terms, words or phrases hereinafter mentioned shall be construed as follows:

(a) Item No.

In Table I an item number is assigned consecutively to each specifically designated waters.

(b) Waters index number as appearing in Table I shall mean that number or abbreviation assigned to any designated waters or portion thereof for the purpose of identification.

(1) The numbering or index system used to identify specific waters of New York State was adapted from that used by the New York State Conservation Department in its biological survey series of reports on watersheds of the State. The primary waters of a drainage area, such as a river, large lake, bay or sound is usually referred to by name or an abbreviation. Tributaries of primary river waters are consecutively numbered progressing upstream from the mouth. Tributaries of primary lake, bay or sound waters are consecutively numbered in a clockwise order from a defined point, usually the outlet of the primary waters. Subtributaries are numbered as encountered along the tributary proceeding from its mouth to the source, and in like manner all of its other stream courses are so numbered. Ponds and lakes are numbered in the order they are encountered within the system. Tributaries of such lakes and ponds are numbered consecutively as they enter, progressing clockwise around the lake or pond from its outlet or mouth. The numbers assigned to such lakes and ponds are prefixed by the letter P. When isolated lakes and ponds are referenced by a waters index number, it it merely for convenience of their identification and location within a subdrainage basin, and it is not necessarily indicative of their being tributary to any waters to which no surface connection is shown on the reference maps.

(2) This system was applied to the basin under consideration by the Conservation Department in its report, A Biological Survey of the Fresh Waters of Long Island—1938, and has been closely followed in connection with the identification of the waters with the following exceptions: Some of the stream numbers do not run consecutively due to the omission of streams originally shown on the older maps employed by the Conservation Department at the time of its survey but not shown on newer maps reproduced herein. Conversely, a few streams not shown on the older maps but appearing on the newer maps are designated by the letters a, b, c, etc.

(3) There are several primary indices used to identify the designated waters. Those waters that drain Long Island proper are identified by waters index numbers prefixed by a hyphen. Those waters within the designated drainage basin that have not been assigned waters index numbers, such as Long Island Sound and Atlantic Ocean, have been identified by an abbreviation of their name. Waters identified by a waters index number or abbreviation, prefixed by a hyphen, are tributary to the nearest preceding waters which have been identified by an abbreviation which is not prefixed by a hyphen.

(4) The system as applied to the identification of waters in the drainage basin of Nassau County may be illustrated as follows:

Waters index number	Name of waters	Explanation
LIS AO	Long Island Sound Atlantic Ocean	Primary waters identified by an abbreviation and not prefixed by a hyphen.
HH MB	Hempstead Harbor Manhasset Bay	These abbreviations are not directly used to index tributaries.
LIS-42	Frost Creek	The 42nd stream encountered on Long Island proceeding in a clockwise direction around the island from Fort Hamilton.
OBH-MNC-45-P 152	Lower Francis Pond	The 152nd pond or lake encountered in the Conservation Department's report, A Biological Survey of the Fresh Waters of Long Island.

(c) The abbreviations trib., tribs., subtrib. and subtribs., indicating tributary, tributaries, subtributary and subtributaries, respectively, shall mean any stream, pond or other body of surface water which flows into any other stream, pond or other body of surface water; where no tributary, tributaries, subtributary or subtributaries are mentioned, the specifically designated waters shall include only the stream, pond or other body of water referenced by such waters index number; where tributary, tributaries, subtributary or subtributaries are mentioned after the waters index number, the specifically designated waters shall include the stream, pond or other body of water referenced by such waters index number and all tributaries and subtributaries thereof which are shown on the reference maps, excluding numbered ponds, unless exceptions are expressly stated.

(d) Name as appearing in Table I shall mean the name by which the specifically designated waters are known and which name may appear on the reference maps. In cases of specifically designated waters which have no name, the named waters to which the unnamed waters are tributary are identified as far as possible.

(e) Description.

The column headed “Description” contains designations of segments or sections of waters under consideration to which a particular assignment of a class and standards shall apply. Also included in this column is any useful information pertinent to the classification or standards.

(f) Map Ref. No. as appearing in Table I means map reference number and indicates one or more of the following numbered maps reproduced herein completely, or in part, on which maps the specifically designated waters and their index numbers are shown within the topographical limit line of the described drainage basins or areas. An index for map numbers is shown on Map 2, quadrangle arrangement, reproduced in section 885.8, infra. The following maps were produced from original maps which may be procured through the Washington Distribution Section, Geological Survey, Silver Spring, Maryland.

(g) Class as appearing in Table I and denoted by the letters A, C, D, SA, SB or SC opposite each specifically designated waters, shall mean class A, C, D, SA, SB or SC, as the case may be, as set forth in Part 701, supra.

(h) Standards as appearing in Table I and denoted by the letters A, C, D, SA, SB or SC opposite each specifically designated waters, shall mean the quality standards established for class A, C, D, SA, SB or SC, as the case may be, established by the aforementioned rules. The symbol (T) appearing after any class designation shall mean that the designated waters are trout waters and that the dissolved oxygen specification for trout waters shall apply thereto. The symbol (TS) after any standard designation shall mean that the designated waters are suitable for trout spawning and that the dissolved oxygen specification for trout spawning waters shall apply hereto.

(i) The term trout as used in this Part means any fish in the following genera: Coregonus, Oncorhynchus, Prosopium, Salmo, Salvelinus and Thymallus.
