Coon Creek, Wisconsin
15.6 mapped river miles, draining 136 square miles, in the Coon Yellow basin watershed. No gauge stands in it; the nearest is 23.8 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 23.8 miles away, at Silver Creek At State Highway 21 Near Angelo, Wi — not a reading of this water, but of what the region is doing today.
The character of the water
Coon Creek is classified almost end to end — 39.1 of its 39.59 NHD miles typed, 99 per cent — and the classification is split rather than uniform: 24.5 miles Cold against 14.6 Cool. On a creek this completely covered that split is a real description of the water rather than an artefact of partial coverage, though these files cannot say which end each class sits at. Wisconsin DNR designates it under all three of its classes, managed as wild, wild supplemented and stocked. There is no gauge in it and no measured temperature. It runs 14.1 feet across at the median, fourth order, draining 136.41 square miles over 15.6 mapped miles. Public ground is slight: three-quarters of a mile of frontage in all, from the Coon Creek Fishery Area and a corner of the Upper Mississippi River refuge. Hasley Creek enters at river mile 14.8.
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 15.6–13.0 | 24.5 | cold | — |
| RM 13.0–0.0 | 14.6 | cool | — |
Wisconsin DNR has classified 39.1 of the 40 miles NHD carries for this stream — 99% of it. The typed water splits 24.5 mi cold, 14.6 mi cool. 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 I, Class II, and Class III. 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 stocked, wild, 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 brook trout into this water 20 times between 2015 and 2024. That is a stocking record rather than a survey — it says the fish were put in, not that a survey has found them since.
WDNR has stocked brown trout into this water 2 times between 2015 and 2017. That is a stocking record rather than a survey — it says the fish were put in, not that a survey has found them since.
WDNR has stocked rainbow trout into this water once, in 2015. 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
51 insects are recorded from the Wisconsin driftless, 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.

Tributaries and watershed
1 named stream meets this one. Confluence miles are above the mouth; the longest twelve are listed.
Coon Creek sits in HUC 8 07060001, the Coon Yellow basin, and drains 136 square miles, Strahler order 4 at the mouth. 92 NHD reaches carry the name for 39.6 miles in total — more than the 15.6 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
