1. (b) Waters index number as appearing in table I shall mean that number or abbreviation 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 number 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 Mohawk-Hudson watershed in 1934 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 1934 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 Mohawk River drainage basin may be illustrated as follows:

      Waters Index Number	Name	Explanation
      H	Hudson River	Primary Waters
      H-240	Mohawk River	The 240th tributary of the Hudson River numbered consecutively upstream from the mouth.
      H-240-144	East Canada Creek	The 144th tributary of the Mohawk River numbered from its confluence with the Hudson River.
      H-240-144-13	Sprite Creek	The 13th tributary of East Canada Creek numbered consecutively upstream from the mouth.
      H-240-144-13-P 717	Canada Lake	The 717th pond, lake or reservoir encountered in the biological survey area of the Mohawk River-Upper Hudson River Watershed.
      H-240-144-13-P 717-3	Irving Pond Outlet	The 3rd tributary of Canada Lake numbered in a clockwise direction from the outlet.

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, lake, pond or other body of surface water. Where no tributaries are mentioned, the specifically designated waters shall include only the stream, pond or other body of surface water designated by such waters index number; where tributaries are mentioned after the waters index number, the specifically designated waters shall include the stream, 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 are identified as far as possible.

   (e) Description.

   The column headed Description contains designations 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 and standard.

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 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.
