104 mapped river miles, draining 419 square miles across Gratiot, Isabella, Montcalm counties, in the Pine subbasin watershed. No gauge stands in it; the nearest is 11.8 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 11.8 miles away, at Wolf Creek At Pine Grove Road Near Vestaburg, Mi — not a reading of this water, but of what the region is doing today.
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: 04154612.
A full river of 104.3 mapped miles through Gratiot, Isabella, and Montcalm counties, the Pine River of the Pine subbasin runs a median 37.7 feet wide and drains 419.32 square miles at Strahler order 5 before reaching the Chippewa River at river mile 0.0. MDNR types 46.9 miles, 45 percent of it: 32.1 miles of Cool, low-gradient warm transitional water from river mile 99.6 to 46.3, and 14.8 miles of Warm, very-low-gradient large river from 42.1 to 22.7. Those are valley classes, not measured water; the nearest gauge, Wolf Creek at Pine Grove Road near Vestaburg, is 11.8 miles off. Type 1 regulations cover 28.1 miles. Brown trout have gone in at Blanchard Rd. at 887.2 per mile and Remick Road at 621.3 per mile, both from 1980 through 2026; walleye at Coldwater/Fremont ran 1981 to 2017 at 769.0 per mile. Public land is thin for the length: 23 units, 5,902 acres, largest the 2,407-acre Edmore State Game Area. No access sites and no surveys are recorded.
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 99.6–46.3 | 32.1 | cool | Warm transitional stream · low gradient |
| RM 42.1–22.7 | 14.8 | warm | Warm large river · very low gradient |
MDNR has classified 46.9 of the 104 miles NHD carries for this stream — 45% of it. The typed water splits 32.1 mi cool, 14.8 mi warm. 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 28.1 of the 104.3 mapped miles; 76.2 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.

47 insects are recorded from southern 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.
