5.4 mapped river miles, draining 5 square miles, in the Sugar basin watershed. No gauge stands in it; the nearest is 9.0 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 9.0 miles away, at Sugar River Near Verona, Wi — not a reading of this water, but of what the region is doing today.
This is inferred, not measured. Wisconsin DNR does not publish a temperature classification for this water. What it publishes is a management tier — whether the trout in it are wild, hold over through summer, or are stocked and fished out — and the bands below are read off that tier, because a stream that sustains wild trout is a cold stream and one that does not hold fish past July is not. It is the agency's judgement of the fishery translated into the four bands this site paints everywhere else; it is not a thermometer, and where the two disagree the thermometer is right.
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 2.8–0.0 | 2.8 | cold | — |
Wisconsin DNR has classified 2.8 of the 5.4 miles NHD carries for this stream — 52% 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 classifies this water as Class I. The management tier on those reaches is wild. 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, 245 acres in total. Acreage is the whole unit, not the part beside the water.
| Unit | Owner | Acres |

| Sugar River State Trail | state natural-resources agency | 245 |
WDNR has stocked brown trout into this water 3 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.
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.

And 37 more — the year-round records, mostly: midges, scuds and sculpins, which are in the water every day and are therefore never the news.
1 named stream meets this one. Confluence miles are above the mouth; the longest twelve are listed.
Ward Creek sits in HUC 8 07090004, the Sugar basin, and drains 5 square miles, Strahler order 2 at the mouth. 13 NHD reaches carry the name for 5.4 miles in total.
