16.2 mapped river miles, draining 43 square miles, in the Finger Lakes basin watershed. No gauge stands in it; the nearest is 25.6 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 25.6 miles away, at Tioga 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 9.9–0.0 | 16.6 | cold | — |
NYSDEC has classified 16.6 of the 23 miles NHD carries for this stream — 72% 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 C — fishing. 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.
