4.9 mapped river miles, draining 14 square miles, in the Upper Hudson basin watershed. No gauge stands in it; the nearest is 4.0 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, 4.0 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.
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 4.9–0.0 | 4.9 | cold | — |
NYSDEC has classified 4.9 of the 5.0 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 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.

NYSDEC designates this as trout water — Trout waters — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
3 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Sand Pond Brook sits in HUC 8 02020001, the Upper Hudson basin, and drains 14 square miles, Strahler order 4 at the mouth. 9 NHD reaches carry the name for 5.0 miles in total.
