20 mapped river miles, draining 35 square miles, in the Keweenaw Peninsula subbasin watershed. No gauge stands in it; the nearest is 11.0 miles away, and what this page knows about its temperature is MDNR'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 15.5 miles away, at Sturgeon River (Baraga) — not a reading of this water, but of what the region is doing today. A closer gauge has stopped reporting — USGS carries no water-temperature series for it at all, so no number here comes from it.
Twenty and a half mapped miles of medium stream in the Keweenaw Peninsula subbasin, a median 13.2 feet wide, draining 34.6 square miles at Strahler order 5. MDNR types two short reaches on high gradient: 2.0 miles from river mile 20.0 to 17.8 as Cold, and 1.8 miles from mile 11.2 to the mouth as Cool, a warm transitional stream. That is 3.8 typed miles, 19 percent of the length, and the class describes the valley segment rather than the water, so no measured temperature exists here; the nearest gauge, on the Ontonagon River, is 11.0 miles off. Regulation splits: 11.5 miles Type 1, last Saturday in April through September 30th, and 7.7 miles Type 3, open year-round. Both allow artificial lures and all types of natural bait, with a creel of 5 fish, no more than 3 trout 15" or greater, and zero Arctic Grayling. Four public units total 47,629 acres, led by 32,939 acres of the Copper Country State Forest Baraga Unit.
MDNR types this water from its valley, not from a thermometer in it. A class, not a temperature — no July mean, because none was measured here.
| Reach | Typed miles | Band | MDNR type |
|---|---|---|---|
| RM 20.0–17.8 | 2.0 | cold | Cold stream · high gradient |
| RM 11.2–0.0 | 1.8 | cool | Warm transitional stream · high gradient |
MDNR has classified 3.8 of the 20 miles NHD carries for this stream — 19% of it. The typed water splits 2.0 mi cold, 1.8 mi cool. The untyped reaches are not warm water — they are water MDNR's inventory does not reach, and the mile ranges above span only the reaches it does.
MDNR trout stream types, as designated. Types on file cover 19.2 of the 20.5 mapped miles; 1.3 miles carry no type in this dataset. Always check the current Michigan Fishing Guide before you fish — this is a copy, and the Guide is the rule.

Trout water by MDNR's classification, which types it cold — a statement about the water's temperature, not a fish record. No MDNR survey or stocking record for this river is in the files this site reads.
42 insects are recorded from the Upper Peninsula, 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.
4 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
West Branch Firesteel River sits in HUC 8 04020103, the Keweenaw Peninsula subbasin, and drains 35 square miles, Strahler order 5 at the mouth. 32 NHD reaches carry the name for 20.5 miles in total.
