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 adopted from that used by the New York State Conservation Department in its biological survey series of reports on the watersheds of the State. The primary waters of a drainage basin such as rivers or large lakes are usually referred to by name or 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 or 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 Lake Ontario watershed in 1939 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 1939 survey, but not shown on newer maps reproduced herein. Conversely, a few streams and ponds 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 Lake Ontario drainage basin may be illustrated as follows:

      Waters index number	Name of waters	Explanation
      Ont.	Lake Ontario	Primary waters.
      Ont. 99	Fourmile Creek	The 99th tributary entering Lake Ontario numbering clockwise from the mouth at Tibbetts Point.
      Ont. 107	Shipbuilders Creek	The 107th tributary entering Lake Ontario numbering clockwise from the mouth at Tibbetts Point.
      Ont. 107-P 112a	Unnamed Pond	Indicates that this body of water is within or adjacent to Shipbuilders Creek sub-basin and follows the 112th pond encountered in the waters index system.

2. (c) The abbreviations trib., tribs., subtrib. and subtribs. indicating tributary, tributaries, subtributary and subtributaries shall mean any stream, lake, pond, or other body of surface water which flows into any other stream, 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 water designated 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 designated 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 by which the specifically designated waters are generally known and which name 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. Also included in this column is any useful information pertinent to the classification or 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 in section 847.9, infra, on which maps the specifically designated waters and their index numbers are shown within the topographical limit line of the described drainage basin.
