1. (b) Waters index number as appearing in table I shall mean that number or abbreviation which has been assigned to any specifically designated waters or portions thereof for the purpose of identification.

   1. (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 basin, such as rivers or large lakes are usually referred to by name or an abbreviation. Tributaries of primary waters are consecutively numbered progressing upstream from the mouth. Ponds and lakes are numbered consecutively as they are encountered, such numbers being preceded by the letter P. Tributaries of such lakes and ponds are numbered consecutively as they enter, progressing clockwise around the lake or pond from its outlet or mouth. When isolated lakes and ponds are referenced by a waters index number, it is 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. (2) This system was applied to the basin under consideration by the Conservation Department in its biological survey of the Upper Hudson River watershed in 1932 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 older maps employed by the Conservation Department at the time of its 1932 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. (3) The system as applied to the identification of waters in the Upper Hudson River drainage basin may be illustrated as follows:

      Waters index number	Name	Explanation
      H	Hudson River	Primary waters within New York State extending upstream from The Battery, New York City.
      H-301	Batten Kill	The 301st tributary entering the Hudson River, numbering consecutively upstream from the mouth at The Battery.
      H-301-17	Whittacker Brook	The 17th tributary entering the Batten Kill numbering upstream from the mouth.
      H-301-17-P 79	Cossayuna Lake	The 79th pond, lake or reservoir encountered in the biological survey of the Upper Hudson River watershed, and specifically located in the drainage basin of Whittacker Brook.
      H-301-17-P 79-4	Unnamed tributary	The 4th tributary entering Cossayuna Lake numbering clockwise from the outlet of the lake.
      H-301-17(3.8)	Whittacker Brook	A point on Whittacker Brook measured three and eight-tenths miles upstream from the mouth, which point is a road crossing at the hamlet of Cossayuna.

2. (c) The abbreviations trib., tribs., subtrib. and subtribs. indicating tributary, tributaries, subtributary and subtributaries, respectively, shall mean any stream, lake, pond or other body of surface water which flows into any other stream, lake, pond or other body of surface water. Where no tributaries or subtributaries are mentioned, the specifically designated waters shall include only the stream, lake, pond or other body of surface water referenced by such waters index number; where tributaries or subtributaries are mentioned after the waters index number, the specifically designated waters shall include the stream, lake, pond or other body of surface water referenced by such waters index number and all tributaries and subtributaries thereof, which are shown on the reference maps, unless exceptions are expressly stated.
3. (d) Name as appearing in table I shall mean the name, if any, by which the specifically designated waters are generally known and which may appear on the reference maps. In cases of specifically designated waters which have no name, the named tributary to which the unnamed waters are tributary is indicated as far as possible.
4. (e) Description as appearing in table I shall mean a brief indication as to the location of the specifically designated waters. Entries may include designations of segments or sections of waters to which a particular assignment of a class and standards shall apply. Entries may also include any useful information pertinent to the classification and standards.

5. (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 the specifically designated waters and their index numbers are shown. The following maps were produced from original maps which may be procured through the Washington Distribution Section, Geological Survey.
