6.0 mapped river miles, draining 19 square miles, in the Southern Long Island basin watershed. No gauge stands in it; the nearest is 2.3 miles away, and what this page knows about its temperature is NYSDEC's classification of the water itself.
50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands, breaking at 58, 64 and 70°F, that the app paints. Grey is water nobody has measured.
The nearest gauge is 2.3 miles away, at Connetquot River — not a reading of this water, but of what the region is doing today.
NYSDEC's classification of this water, reach by reach. A class, not a temperature — no July mean, because none was measured here.
| Reach | Typed miles | Band | NYSDEC type |
|---|---|---|---|
| RM 6.0–0.2 | 5.6 | cold | — |
NYSDEC has classified 5.6 of the 6.1 miles NHD carries for this stream — 91% of it. Every typed reach carries the same class, cold. The untyped reaches are not warm water — they are water NYSDEC's inventory does not reach, and the mile ranges above span only the reaches it does.
NYSDEC classifies this water as Class B — swimming and contact recreation, Class C — fishing, and Class SC — fishing, saline. More than one class appears because the classification changes along the river. The thermal bar above shows where. On those reaches DEC also designates it trout spawning waters, trout waters — which is the half of the classification that is about temperature, and the half this map paints by. The class is a designation of best usage under 6 NYCRR — what the water is protected for — and not the season and creel rules, which change yearly and live with the agency.

NYSDEC designates this as trout water — Trout spawning waters, Trout waters — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
1 named stream meets this one. Confluence miles are above the mouth; the longest twelve are listed.
Connetquot Brook sits in HUC 8 02030202, the Southern Long Island basin, and drains 19 square miles, Strahler order 2 at the mouth. 20 NHD reaches carry the name for 6.1 miles in total — more than the 6.0 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
