BirdTrout
Big Brook, Michigan
22 mapped river miles, draining 39 square miles, in the Cedar-Ford subbasin watershed. No gauge stands in it; the nearest is 9.9 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, and why there is no reading from it
The nearest gauge, 9.9 miles away at Menominee River, is not reporting water temperature: its water-temperature series is empty, and was last stamped 11 June 2026. A stopped gauge repeats its last value in silence, so there is no live temperature here. What is below is modelled from the years that gauge did report: this gauge's own fitted line, its intercept plus its slope against the 3-day mean air temperature over it, fitted on its own daily record, ±2.8 °F. The shape of the week at that gauge, not a thermometer in this stream.

Hatches on this water
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.
