Hyner Run, Pennsylvania

2.5 mapped river miles, draining 29 square miles, in the Middle West Branch Susquehanna basin watershed. No gauge stands in it; the nearest is 4.0 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

The nearest gauge is 13.2 miles away, at Kettle Creek At Cross Fork, Pa — not a reading of this water, but of what the region is doing today. A closer gauge has stopped reporting — its water-temperature series is empty, and was last stamped 25 June 2025, so no number here comes from it.

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 2.5–0.0 6.2 cold —

PA DEP has classified 6.2 of the 7.1 miles NHD carries for this stream — 87% 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.
