Part 920: Moriches Bay Drainage Basin

(Statutory authority: Environmental Conservation Law, § 17-0301)

Contents:

Sec.

§920.1 Adopting Order

Pursuant to article 17 of the Environmental Conservation Law, after proper study and following public hearings held on due notice, the Department of Environmental Conservation hereby adopts and assigns the following classifications and standards of quality and purity to all surface waters within the designated drainage basin of Moriches Bay within Suffolk County, as hereinafter described.

§920.2 Definitions and Conditions

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 or portion thereof.

(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 are 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 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) This system was applied to the waters under consideration by the New York State Conservation Department in its Biological Survey of the Lower Hudson Watershed and Biological Survey of the Fresh Waters of Long Island in 1936 and 1938, respectively, and has been closely followed in connection with the numerical 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 1936 and 1938 surveys but not shown on later editions of maps reproduced herein. Conversely, streams, lakes and ponds not shown on the older maps but appearing on the newer maps are designated by suffix letters a, b, c, etc.

(3) The system as applied to the identification of the designated waters may be outlined as follows: There are several primary indices used to identify the designated waters. Those waters that drain Moriches Bay proper are identified by waters index numbers prefixed by the abbreviation MB. Waters draining Narrow Bay proper are identified by waters index numbers prefixed by the abbreviation NB. Waters of Tuthill Cove, Hart's Cove, Seatuck Cove, Speonk Cove and Beaverdam Cove are identified by TC, HC, SC, SPC and BC, respectively, prefixing the waters index numbers.

(4) The following table will illustrate how the designated waters may be identified through the use of the waters index system:

Waters Index Number Name of Waters Explanation
NB-1, NB-2 Narrow Bay Primary waters identified by an abbreviation.
NB-2-176 Pattersquash Creek The 176th stream encountered on Long Island proceeding in a clockwise direction around the island from Fort Hamilton (The Narrows).
MB-1, MB-2 MB-3, MB-4, MB-5, MB-6 Moriches Bay Primary waters identified by an abbreviation.
MB-1-174 Forge River The 174th stream encountered on Long Island proceeding in a clockwise direction around the island from Fort Hamilton (The Narrows).
MB-1-174-2 Old Neck Creek The second tributary entering the Forge River above the mouth.
MB-1-174-P 850 West Pond The 850th pond or lake encountered in the biological survey area of the Atlantic Ocean- Long Island Sound watershed.

(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 a 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 the specifically designated waters and their index numbers are shown.

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

Map Ref. No. Name of Quadrangle Edition Published By
1 Bellport 1947 U.S. Geological Survey
2 Moriches 1947 U.S. Geological Survey
3 Eastport 1947 U.S. Geological Survey

(2) The above-mentioned maps have been consolidated in section 920.6, infra, and are hereinafter known as Map 2.

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

(h) Standards, as appearing in Table I and denoted by the letters B, C, SA, SC and SD opposite each specifically designated waters, shall mean the quality standards established for Class B, C, SA, SC and SD, as the case may be, as set forth in Part 701, supra. 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 class designation shall mean that the designated waters are suitable for trout spawning and that the dissolved oxygen specification for trout spawning waters shall apply thereto.

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

(j) The Moriches Bay drainage basin shall be deemed to include the following areas:

(1) that portion of the Atlantic Ocean within the boundaries of New York State extending from a line passing due south through Potunk Point to a line passing due south through Smith Point;

(2) all of Moriches Bay and Narrow Bay as defined in Table I included herein; and

(3) all land and water areas which are directly or indirectly tributary to Moriches Bay or Narrow Bay, except those tidal salt waters which are tributary to said bays easterly of Potunk Point and westerly of Smith Point.

(k) Unless otherwise expressly defined in Table I, the mouth of any stream or estuary shall be considered to be represented by a continuation of the shoreline of the bay, cove, river, estuary or creek to which such stream or estuary is tributary across the channel axis of such tributary stream or estuary.

(l) All streams, ponds, estuaries or other bodies of water which appear as lines, to indicate natural waters, on the reference maps herein, and which are not specifically designated in Table I, shall be assigned the same classes and standards of quality and purity as the specifically designated waters to which they are directly tributary.

(m) All streams, ponds, estuaries or other bodies of water which are not shown on the reference maps herein shall be assigned to Class D, as set forth in Part 701, supra, except that any continuous flowing natural stream which is not shown on the reference maps shall have the same classification and assigned standards as the waters to which it is directly tributary; or, if they be tidal salt waters, such waters which are not shown on the reference maps herein shall be assigned to Class SD, as set forth in Part 701, supra, except that any continuous flowing natural stream which is not shown on the reference maps shall have the same classification and assigned standards as the waters to which it is directly tributary.
