19.8 mapped river miles, draining 32 square miles, in the Conococheague Opequon basin watershed. No gauge stands in it; the nearest is 14.5 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 14.5 miles away, at Cacapon River — not a reading of this water, but of what the region is doing today.
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 19.8–9.6 | 10.3 | cold | — |
| RM 8.0–0.0 | 8.7 | cool | — |
PA DEP has classified 19.0 of the 29 miles NHD carries for this stream — 65% of it. The typed water splits 10.3 mi cold, 8.7 mi 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 Cold Water Fishes and Trout Stocking. More than one class appears because the classification changes along the river. The thermal bar above shows where. The management tier on those reaches is Cold Water Fishes, Trout Stocking. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.
2 units of public or open-access land touch this river, 7,708 acres in total. Acreage is the whole unit, not the part beside the water.
| Unit | Owner | Acres |
|---|---|---|
| State Game Land 128 | another state agency | 1,709 |
| State Game Land 065 | another state agency | 5,999 |
PA DEP designates this as trout water — Cold Water Fishes, Trout Stocking — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
7 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Little Tonoloway Creek sits in HUC 8 02070004, the Conococheague Opequon basin, and drains 32 square miles, Strahler order 5 at the mouth. 90 NHD reaches carry the name for 29.2 miles in total — more than the 19.8 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
