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.
The nearest gauge is 11.5 miles away, at Au Sable River Near Au Sable — not a reading of this water, but of what the region is doing today.
The Tawas River is a Lake Huron tributary with 6.0 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 Tawas River →
MDNR trout stream types, as designated. Types on file cover 6.0 of the 6.1 mapped miles; 0.1 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.

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.
