83 mapped river miles, draining 754 square miles across Macomb, Oakland counties, in the Clinton subbasin watershed. A USGS gauge stands in it, but its record is too short for a measured July mean, so what this page knows about its temperature is today's reading and 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 13.2 miles away, at Clinton River At Sterling Heights — not a reading of this water, but of what the region is doing today. A closer gauge has stopped reporting — USGS carries no water-temperature series for it at all, so no number here comes from it.
Strahler order 7 and 753.56 square miles of drainage across Macomb and Oakland counties, yet a median width of only 26.8 feet over 83.2 mapped miles. MDNR types 30.6 miles, 37 percent, and the sequence alternates: Cool for 1.2 miles from river mile 82.0 to 74.7, Warm for 3.8 miles to mile 52.0, Cool again for 5.0 miles from 49.3 to 37.4 as a warm transitional small river, then Warm for 20.6 miles from mile 32.6 to the mouth as a warm large river on low gradient. Those classes describe the valley segment, not the water, so no measured temperature exists here despite a gauge sitting on the river at Drayton Plains. Type 4 regulation covers 31.0 miles, open January 1st through December 31st. Stocking is heavy and current: Ryan Road at 3,096.7 per mile and Hamlin Road at 1,380.4 per mile, both running through 2026, along with brown and rainbow trout at Squirrel Road.
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 82.0–74.7 | 1.2 | cool | Warm transitional stream · medium gradient |
| RM 73.3–52.0 | 3.8 | warm | Warm stream · very low gradient |
| RM 49.3–37.4 | 5.0 | cool | Warm transitional small river · medium gradient |
| RM 32.6–0.0 | 20.6 | warm | Warm large river · low gradient |
MDNR has classified 30.6 of the 83 miles NHD carries for this stream — 37% of it. The typed water splits 24.4 mi warm, 6.2 mi cool. 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 31.0 of the 83.2 mapped miles; 52.2 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.

Stocked, per the MDNR record: Brown trout, Chinook salmon, Coho salmon, Rainbow trout, Walleye. The most recent plants are Brown trout, Rainbow trout at Squirrel Road (Oakland Co., through 2026); Brown trout at Hamlin Road (Oakland Co., through 2026); Rainbow trout at Ryan Road (Macomb Co., through 2026).
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.
