1. (b) Waters index number as appearing in table I shall mean that number assigned to any designated waters for the purpose of identification.

   1. (1) The numbering or index system used to identify specific waters of New York was adapted from that used by the New York State Conservation Department in its stocking lists. The primary waters of a drainage basin, a stream or large lake, is referred to by name or abbreviation. Ponds and lakes are numbered consecutively as they are encountered, such number being preceded by the letter P. This system also involves the consecutive numbering or tributaries as they enter a stream, progressing upstream from the mouth. Tributaries of lakes or ponds are numbered consecutively as they enter, progressing clockwise around the lake or pond from its outlet or mouth. Isolated lakes and ponds are referenced by a waters index number 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 “Revised Stocking List of the Genesee River System — March 1952” 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 the list's publication 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 Genesee River drainage basin may be illustrated as follows:

      Waters index number	Name	Explanation
      Ont.	Lake Ontario	Primary waters.
      Ont. 117	Genesee River	A primary drainage basin of the State numbering clockwise from the St. Lawrence River.
      Ont. 117-27	Honeoye Creek	The 27th tributary of the Genesee River numbering from the mouth upstream.
      Ont. 117-27-34	Hemlock Outlet	The 34th tributary of Honeoye Creek numbering from the mouth upstream.
      Ont. 117-27-34 -P 44	Hemlock Lake	The 44th pond encountered in the Genesee River drainage basin.
      Ont. 117-27-34 -P 44-7	Springwater Creek	The 7th tributary of Hemlock Lake numbering clockwise from the mouth.

2. (c) The abbreviations trib and tribs indicating tributary and tributaries, and the terms subtributary and subtributaries 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 water 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.

3. (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 or standards shall apply. Also, included in this column is any useful information pertinent to the classification or standards.

4. (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 basin.

   1. (1) The following maps were produced from original maps which may be procured through the Washington Distribution Section, Geological Survey, Silver Spring, Maryland.
