Scuppernong River, Wisconsin
14.6 mapped river miles, draining 80 square miles, in the Rock basin watershed. No gauge stands in it; the nearest is 26.4 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 26.4 miles away, at Fox River Near New Munster, Wi — not a reading of this water, but of what the region is doing today.
The character of the water
The Scuppernong is Class II and Class III water under Wisconsin DNR, managed as wild supplemented and as stocked, and the thermal classification barely reaches it: 4.4 miles typed out of 19.18 NHD miles, 23 per cent, split 3.4 Cool against 1.0 Cold. Under a quarter of the river classified says very little about the river. There is no gauge in it; the nearest is on the Milwaukee, thirty-six miles away. The channel is 13.8 feet across at the median, fifth order, draining 79.56 square miles over the 14.6 miles of axis mapped. The public ground is the striking fact: 7.27 miles of the river run inside the southern unit of the Kettle Moraine State Forest, half the mapped length. No named tributary is recorded entering it.
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 14.6–13.6 | 1.0 | cold | — |
| RM 13.6–10.2 | 3.4 | cool | — |
| RM 9.6–9.5 | 0.0 | cold | — |
Wisconsin DNR has classified 4.4 of the 19.2 miles NHD carries for this stream — 23% of it. The typed water splits 3.4 mi cool, 1.0 mi 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 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.

Public land on the river
1 unit of public or open-access land touches this river, 22,889 acres in total. Acreage is the whole unit, not the part beside the water.
| Unit | Owner | Acres |
|---|---|---|
| Kettle Moraine State Forest-Southern Unit | state natural-resources agency | 22,889 |
Species
WDNR has stocked brook trout into this water 10 times between 2015 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.

Tributaries and watershed
Scuppernong River sits in HUC 8 07090001 and 07090002, the Rock basin, and drains 80 square miles, Strahler order 5 at the mouth. 62 NHD reaches carry the name for 19.2 miles in total — more than the 14.6 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
