11.2 mapped river miles, draining 37 square miles, in the Upper Ohio basin watershed. No gauge stands in it; the nearest is 16.2 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 gauge is 19.6 miles away, at Allegheny R At Cw Bill Young L&d At Acmetonia, Pa — not a reading of this water, but of what the region is doing today. A closer gauge has stopped reporting — USGS carries no water-temperature series for it at all, so no number here comes from it.
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 11.2–0.0 | 13.6 | cool | — |
PA DEP has classified 13.6 of the 13.7 miles NHD carries for this stream — 99% of it. Every typed reach carries the same class, cool. 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.
PA DEP classifies this water as Trout Stocking. The management tier on those reaches is Trout Stocking. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.
9 units of public or open-access land touch this river, 1,045 acres in total. Acreage is the whole unit, not the part beside the water.

PA DEP designates this as trout water — Trout Stocking — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
5 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Montour Run sits in HUC 8 05030101, the Upper Ohio basin, and drains 37 square miles, Strahler order 4 at the mouth. 15 NHD reaches carry the name for 13.7 miles in total — more than the 11.2 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
