130 mapped river miles, draining 867 square miles across Livingston, Oakland, Washtenaw, Wayne counties, in the Huron 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 12.1 miles away, at Lower River Rouge At Wayne — not a reading of this water, but of what the region is doing today. A closer gauge has stopped reporting — it has sent no water temperature for 4745 days, since 1 October 2013, so no number here comes from it.
A river, sixth order, 129.5 mapped miles across Livingston, Oakland, Washtenaw and Wayne counties in the Huron subbasin, draining 866.64 square miles at a median width of 30.1 feet. MDNR types only 5.4 miles, 4 percent coverage: 0.7 typed miles of Cool between river miles 129.5 and 125.0, and 4.7 typed miles of Warm from river mile 117.9 down to 57.8. MDNR classes the valley segment, not the water: no measured temperature exists; a gauge at Ann Arbor sits on the river itself. Regulation splits between 3.8 miles of Type 1, last Saturday in April through September 30th, and 28.1 miles of Type 4 open year-round. A 2018 survey in Washtenaw County at a mean width of 125.52 feet recorded smallmouth bass under general regulation, with no trout or pounds per acre. Stocking runs through 2026 with brown and rainbow trout at 1,161.1 per mile and rainbow at Rockwood at 11,955.3 per mile. Eighty public land units total 30,179 acres; one access site, one launch.
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 129.5–125.0 | 0.7 | cool | Warm transitional stream · medium gradient |
| RM 117.9–57.8 | 4.7 | warm | Warm stream · low gradient |
MDNR has classified 5.4 of the 129 miles NHD carries for this stream — 4% of it. The typed water splits 4.7 mi warm, 0.7 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 31.9 of the 129.5 mapped miles; 97.6 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.

MDNR's most recent survey on this river ran in 2018 at Huron River, Washtenaw County, in a channel averaging 125.52 feet: smallmouth bass. MDNR strata: medium, smallmouth bass; regulation at the station, general regulation.The station has been surveyed in 6 years since 2005.
Stocked, per the MDNR record: Brown trout, Channel catfish, Coho salmon, Rainbow trout, Walleye. The most recent plants are Brown trout, Rainbow trout at Huron River (Oakland Co., through 2026); Rainbow trout at Huron River In Rockwood (Wayne Co., through 2026); Channel catfish at Island Lake Recreation Area (Livingston Co., through 2011).
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.
