Twentymile Creek, Pennsylvania
19.9 mapped river miles, draining 33 square miles, in the Lake Erie Tributaries basin watershed. No gauge stands in it; the nearest is 28.9 miles away, and what this page knows about its temperature is PA DEP'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 live reading

Thermal classification
PA DEP'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 | PA DEP type |
|---|---|---|---|
| RM 7.1–0.0 | 7.1 | cold | — |
PA DEP has classified 7.1 of the 20 miles NHD carries for this stream — 35% of it. Every typed reach carries the same class, cold. The untyped reaches are not warm water — they are water PA DEP's inventory does not reach, and the mile ranges above span only the reaches it does.
