Red River, Wisconsin
22 mapped river miles, draining 159 square miles, in the Wolf basin watershed. A USGS gauge stands in it, but its record is too short for a measured July mean, so what this page knows about its temperature is today's reading and 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
This gauge stands in the Red River. Its record is too short for a July mean, so the class below is Wisconsin DNR's — but the reading is this water.
The character of the water
Wisconsin DNR designates the Red Class II and Class III, managed as wild supplemented and as stocked, and has typed 89 per cent of its 48.73 NHD miles: 26.5 miles classed Cold against 16.7 classed Cool, 43.2 in all. That split is the fact worth carrying — this is not one thermal regime end to end, and these pages cannot say which end each class sits at. There is no gauge in the river and no measured temperature. It runs 17.8 feet across at the median, fourth order, draining 159.06 square miles over the 22.4 miles of axis mapped. No block of public land in these files fronts it, and Wisconsin has no access file, so this page can say nothing about where the bank is open. Mayking Creek comes in high at river mile 19.7 and Camp Creek at 12.6; the West Branch meets the river at the mouth.
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.

Wisconsin DNR has classified 43.2 of the 49 miles NHD carries for this stream — 89% of it. The typed water splits 26.5 mi cold, 16.7 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 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.
WDNR trout stream classification →
Species
WDNR has stocked brown trout into this water 3 times between 2016 and 2018. 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 6 times between 2019 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.

And 28 more — the year-round records, mostly: midges, scuds and sculpins, which are in the water every day and are therefore never the news.
Tributaries and watershed
3 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Red River sits in HUC 8 04030202, the Wolf basin, and drains 159 square miles, Strahler order 4 at the mouth. 91 NHD reaches carry the name for 48.7 miles in total — more than the 22.4 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
