Water temperature — the colour of the river, and of every dot on it

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.

Live from the USGS — every pill above is live, so the numbers you are reading are the latest continuous readings at each gauge. Provisional and unreviewed, as all real-time data is. If that fetch cannot happen — you are offline, or the USGS is down — the pills fall back to the last value we cached, 30 September 2026, 14:04 UTC.

Thermal classification

Each gauge carries a July mean built from its own daily record — 8 Julys, 2019–2026, measured rather than modelled. A July mean is what decides which of the four bands a stretch of water belongs to, because July is when a trout river either holds or does not.

Reach July mean Band Groundwater
Youghiogheny R at Dam Outlet Tunnel Nr Confluence
RM 16.8–0.0
55.4 °F cold high
Dam, Pa
RM -39.2–0.0
55.2 °F cold high
Confluence, Pa
RM -40.2–0.0
57.5 °F cold high
Sutersville, Pa
RM -69.3–0.0
76.7 °F warm low

Every gauge sits at the bottom of its segment, so each number is the warm end and the water above it runs colder. ±2.48 °F on the fit.

Questions about this river

PA DEP classification

PA DEP classifies this water as Cold Water Fishes and Warm Water Fishes. 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, Warm Water Fishes. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.

Fishable reaches

River miles are measured above the mouth, along the mapped mainstem. The reach breaks are the gauges, which is also how the temperature model divides the river.

Species

PA DEP designates this as trout water — Cold Water Fishes — without naming the species. No fish survey or stocking record for this water is in the files this site reads.

Tributaries and watershed

4 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.

Youghiogheny River sits in HUC 8 05020006, the Youghiogheny River basin, and drains 429 square miles, Strahler order 5 at the mouth. 223 NHD reaches carry the name for 92.9 miles in total — more than the 16.8 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
