6.1 mapped river miles, draining 153 square miles across Iosco county, in the Au Gres-Rifle subbasin watershed. No gauge stands in it; the nearest is 11.5 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.

Hatches on this water

53 insects are recorded from northern lower Michigan, 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.
