Kelly Brook, Wisconsin
15.7 mapped river miles, draining 58 square miles, in the Oconto basin watershed. No gauge stands in it; the nearest is 12.3 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 12.3 miles away, at Oconto River Near Oconto, Wi — not a reading of this water, but of what the region is doing today.
The character of the water
Kelly Brook is Class I water under Wisconsin DNR, managed as wild, with 16.3 of its 29.16 NHD miles typed Cold — 56 per cent, and no reach classed anything else. A wild designation over water that is cold wherever it has been typed is the strongest thing these files say about a stream, and it covers a little over half of this one. There is no gauge in it; the nearest is on the Oconto, 12.3 miles off, and its July mean of 74.7 °F belongs to that river. The brook is 16.7 feet across at the median, fourth order, draining 58.5 square miles over the 15.7 miles of axis mapped. No block of public land in these files fronts it and no named tributary is recorded, so where a reader may stand is not something this page can answer.
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 15.7–12.7 | 16.3 | cold | — |
Wisconsin DNR has classified 16.3 of the 29 miles NHD carries for this stream — 56% 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.

Species
Wisconsin DNR designates this as trout water — Class I — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
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.
