11.5 mapped river miles, draining 18 square miles, in the Black basin watershed.
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.
There is no USGS gauge within 40 miles of this stream in the record this site holds, so there is no live temperature on this page and no measured July mean. Everything below the bar is NYSDEC's own classification of the water.
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 11.5–0.0 | 21.6 | cold | — |
NYSDEC has classified 21.6 of the 22 miles NHD carries for this stream — 99% 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 and Class C — fishing. 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.
2 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Alder Creek sits in HUC 8 04140301, the Black basin, and drains 18 square miles, Strahler order 4 at the mouth. 111 NHD reaches carry the name for 21.8 miles in total — more than the 11.5 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
