Graham Creek, Wisconsin
4.8 mapped river miles, draining 8 square miles, in the Lower Chippewa basin watershed. No gauge stands in it; the nearest is 25.0 miles away, and what this page knows about its temperature is Wisconsin DNR'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, and why there is no reading from it
The nearest gauge, 25.0 miles away at Drywood Creek At Covered Footbridge Nr Cadott, Wi, is not reporting water temperature: its water-temperature series is empty, and was last stamped 23 December 2024. A stopped gauge repeats its last value in silence, so there is no live temperature here. What is below is modelled from the years that gauge did report: this gauge's own fitted line, its intercept plus its slope against the 3-day mean air temperature over it, fitted on its own daily record, ±1.7 °F. The shape of the week at that gauge, not a thermometer in this stream.
Thermal classification
Wisconsin DNR'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 | Wisconsin DNR type |
|---|---|---|---|
| RM 4.8–0.0 | 4.8 | cold | — |
Wisconsin DNR has classified 4.8 of the 4.8 miles NHD carries for this stream — 99% of it. Every typed reach carries the same class, cold. The untyped reaches are not warm water — they are water Wisconsin DNR's inventory does not reach, and the mile ranges above span only the reaches it does.

Wisconsin DNR classification
Wisconsin DNR classifies this water as Class II. The management tier on those reaches is wild supplemented. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.

Species
WDNR has stocked brown trout into this water 10 times between 2015 and 2025. That is a stocking record rather than a survey — it says the fish were put in, not that a survey has found them since.
Hatches on this water
42 insects are recorded from northern Wisconsin, which is the region this river sits in. That is a claim about the region and not a survey of this stream: nobody has recorded which of them has been caught here. Open the river in the app and the hatch panel will narrow it to the ones whose temperature window today's reading is inside.
