14.0 mapped river miles, draining 76 square miles, in the Black basin watershed. No gauge stands in it; the nearest is 32.3 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 32.3 miles away, at La Crosse River @ Cnty Trunk Highwy Bb Nr Tomah,wi — not a reading of this water, but of what the region is doing today.
Halls Creek is Class II water under Wisconsin DNR, managed as wild supplemented, with 12.9 of its 26.51 NHD miles typed Cold — 49 per cent, and no reach classed otherwise. There is no gauge in it and no measured temperature. It is 13.4 feet across at the median, fifth order, draining 75.57 square miles over the 14 miles of axis mapped. The public ground on it is unusually well matched to the water: the Halls (Stockwell) Creek Fishery Area is 812 acres and 8.38 miles of the creek run inside it — three-fifths of the mapped length under one owner, which is what a fishery area is bought to do. The South Fork comes in near the bottom at river mile 1.4, and the East Fork meets the creek at the mouth.
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 14.0–1.1 | 12.9 | cold | — |
Wisconsin DNR has classified 12.9 of the 27 miles NHD carries for this stream — 49% 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 II. The management tier on those reaches is 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 →
1 unit of public or open-access land touches this river, 812 acres in total. Acreage is the whole unit, not the part beside the water.
| Unit | Owner | Acres |
|---|---|---|
| Halls (Stockwell) Creek Fishery Area | state natural-resources agency | 812 |
WDNR has stocked brook trout into this water 9 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.
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.
2 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Halls Creek sits in HUC 8 07040007, the Black basin, and drains 76 square miles, Strahler order 5 at the mouth. 41 NHD reaches carry the name for 26.5 miles in total — more than the 14.0 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
