13.1 mapped river miles, draining 22 square miles, in the Nemadji basin watershed. No gauge stands in it; the nearest is 22.5 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 is 22.8 miles away, at Saint Louis River — not a reading of this water, but of what the region is doing today. A closer gauge has stopped reporting — USGS carries no water-temperature series for it at all, so no number here comes from it.
The pills above go to USGS. These are this site's pages for the same gauges — a thirty-day chart, the monthly means, the record, and today's reading against the five-year normal for today: 04026005.
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 13.1–6.0 | 7.1 | cold | — |
| RM 6.0–0.0 | 6.9 | cool | — |
Wisconsin DNR has classified 14.0 of the 14.2 miles NHD carries for this stream — 98% of it. The typed water splits 7.1 mi cold, 6.9 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 classifies this water as 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 supplemented. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.

1 unit of public or open-access land touches this river, 295,165 acres in total. Acreage is the whole unit, not the part beside the water.

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

Little Amnicon River sits in HUC 8 04010301, the Nemadji basin, and drains 22 square miles, Strahler order 4 at the mouth. 30 NHD reaches carry the name for 14.2 miles in total — more than the 13.1 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
