Rush River, Wisconsin
15.3 mapped river miles, draining 207 square miles, in the Rush Vermillion basin watershed. No gauge stands in it; the nearest is 7.2 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 7.2 miles away, at Eau Galle River At Spring Valley, Wi — not a reading of this water, but of what the region is doing today.
The character of the water
The Rush is Class I and Class II water under Wisconsin DNR, managed as wild and as wild supplemented, with 36.5 of its 54.12 NHD miles typed Cold — 67 per cent, and nothing classed otherwise. There is no gauge in it and no measured temperature. The channel is 22.3 feet across at the median, fifth order, draining 207.25 square miles over the 15.3 miles of axis mapped. Public ground is slight against that: two parcels of the Western Prairie habitat restoration area, 124 acres each, covering the same 0.71 of a mile of river between them. No named tributary is recorded entering along the mapped length, and Wisconsin has no access file, so most of what this page can say about the Rush is in its size and its class.
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 0.9–0.0 | 36.5 | cold | — |
Wisconsin DNR has classified 36.5 of the 54 miles NHD carries for this stream — 67% 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 classification
Wisconsin DNR classifies this water as Class I and Class II. 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 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
Wisconsin DNR designates this as trout water — Class I, Class II — without naming the species. No fish survey or stocking record for this water is in the files this site reads.
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
Rush River sits in HUC 8 07040001, the Rush Vermillion basin, and drains 207 square miles, Strahler order 5 at the mouth. 189 NHD reaches carry the name for 54.1 miles in total — more than the 15.3 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
