Alder Creek, New York
8.6 mapped river miles, draining 16 square miles, in the Upper Hudson basin watershed. No gauge stands in it; the nearest is 13.9 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, and why there is no reading from it
The nearest gauge, 13.9 miles away at Durgin Brook At Boreas River Ny, is not reporting water temperature: USGS carries no water-temperature series for it at all. A stopped gauge repeats its last value in silence, so there is no live temperature here. What is below is modelled from the years that gauge did report: this gauge's own fitted line, its intercept plus its slope against the 4-day mean air temperature over it, fitted on its own daily record, ±1.8 °F. The shape of the week at that gauge, not a thermometer in this stream.
Thermal classification
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 4.3–0.0 | 4.3 | cold | — |
NYSDEC has classified 4.3 of the 8.7 miles NHD carries for this stream — 50% 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 classification
NYSDEC classifies this water as Class C — fishing. On those reaches DEC also designates it 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.

Tributaries and watershed
3 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.

Alder Creek sits in HUC 8 02020001, the Upper Hudson basin, and drains 16 square miles, Strahler order 3 at the mouth. 20 NHD reaches carry the name for 8.7 miles in total — more than the 8.6 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
