52 mapped river miles, draining 910 square miles, in the Escanaba subbasin watershed. 3 USGS gauges report water temperature on it, and this page reads all 3.
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.
Live from the USGS — every pill above is live, so the numbers you are reading are the latest continuous readings at each gauge. Provisional and unreviewed, as all real-time data is. If that fetch cannot happen — you are offline, or the USGS is down — the pills fall back to the last value we cached, 30 September 2026, 13:43 UTC.
The pills above go to USGS. These are this site's pages for the same gauges — a thirty-day chart, the monthly means, the record, and today's reading against the five-year normal for today: 04057800, 04057801.
A wide river by the numbers, a median 63.7 feet across 52.2 mapped miles, draining 910.38 square miles at Strahler order 5. Temperature here rests on a gauge rather than a valley class: Escanaba River at Cornell, river mile 1.5, covering a 50.8-mile reach with a July mean of 70.8 F, a July range of 18.9 F, and an uncertainty of 1.97 F over eight Julys of record from 2019 through 2026. Groundwater input is rated low. That gauge sits at the downstream end of its reach, so the mean stands for the warmest water in it and everything above runs colder. Type 1 regulation covers 30.2 miles, last Saturday in April through September 30th, artificial lures and all types of natural bait, creel of 5 fish with no more than 3 trout 15" or greater. Eight public units total 179,695 acres, dominated by the Gwinn Management Unit at 159,228.
Each gauge carries a July mean built from its own daily record — 4 Julys, 2023–2026, measured rather than modelled. A July mean is what decides which of the four bands a stretch of water belongs to, because July is when a trout river either holds or does not.
| Reach | July mean | Band | Groundwater |
|---|---|---|---|

Middle Branch at Humboldt RM 52.2–42.7 |
66.8 °F | cool | moderate |

Every gauge sits at the bottom of its segment, so each number is the warm end and the water above it runs colder. ±1.97 °F on the fit.
The Escanaba River is a Lake Michigan tributary with 1.4 miles of run corridor on it — salmon, steelhead and lake-run brown trout, on their own calendar and under their own rules. Run timing, species and access on the Escanaba River →
MDNR trout stream types, as designated. Types on file cover 30.2 of the 52.2 mapped miles; 22.0 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.

River miles are measured above the mouth, along the mapped mainstem. The reach breaks are the gauges, which is also how the temperature model divides the river.

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.
15 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Escanaba River sits in HUC 8 04030110, the Escanaba subbasin, and drains 910 square miles, Strahler order 5 at the mouth. 42 NHD reaches carry the name for 52.2 miles in total.
