1.1 mapped river miles, draining 10 square miles, in the St. Clair subbasin watershed. No gauge stands in it; the nearest is 12.3 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, 12.3 miles away at Pine River At Neuman Road Near Marysville, Mi, is not reporting water temperature: USGS carries no water-temperature series for it at all. A stopped gauge repeats its last value in silence, so there is no live temperature here. Nor is there a model to put in its place: that gauge has too little record to fit one, and this site does not print a temperature it cannot stand behind.
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 1.1–0.0 | 0.8 | warm | Warm stream · high gradient |
MDNR has classified 0.8 of the 1.1 miles NHD carries for this stream — 70% of it. Every typed reach carries the same class, 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.

No species records for this water in the files this site reads.
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.
