Scarboro Creek, Wisconsin
13.9 mapped river miles, draining 22 square miles, in the Lakeshore basin watershed. No gauge stands in it; the nearest is 5.4 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 live reading
The nearest gauge is 5.4 miles away, at Kewaunee River — not a reading of this water, but of what the region is doing today.
The character of the water
Scarboro Creek is Class II water under Wisconsin DNR, managed as wild supplemented, and the thermal classification reaches a quarter of it: 4.2 miles typed Cold out of 15.92 NHD miles, 26 per cent, with nothing classed otherwise. There is no gauge in it; the nearest is on the Fox, 15.3 miles away. It is 7.6 feet across at the median — narrow — fourth order, draining 21.68 square miles over the 13.9 miles of axis mapped. Public ground is a corner of the Ahnapee State Trail corridor fronting seven-hundredths of a mile, which is a crossing rather than a bank. No named tributary is recorded, and Wisconsin has no access file, so the class and the size are most of what this page holds.
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 2.3–0.0 | 4.2 | cold | — |
Wisconsin DNR has classified 4.2 of the 15.9 miles NHD carries for this stream — 26% 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 2016 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.
