48 mapped river miles, draining 111 square miles across Genesee, Oakland counties, in the Flint subbasin watershed. No gauge stands in it; the nearest is 11.2 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, 11.2 miles away at Shiawassee River At Fish Lake Rd At Holly, 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.
A medium stream of the Flint subbasin, 47.9 mapped miles through Genesee and Oakland counties, fifth order, draining 110.88 square miles at a median width of 17.4 feet. MDNR types 3.7 miles, 8 percent coverage: a Cool reach of 2.0 typed miles between river miles 46.4 and 37.5 at medium gradient, and a Warm reach of 1.7 typed miles from river mile 3.1 to the mouth. MDNR classes the valley segment, not the water: no measured temperature exists; the nearest gauge, on the Shiawassee River at Fish Lake Rd at Holly, is 11.2 miles away. Type 1 regulation covers 9.8 miles, last Saturday in April through September 30th, five fish with no more than three trout 15 inches or greater. Brown trout stocking continues through 2026 at Oakwood Road, begun 1979, at 862.0 per mile, with two more sites running through 2021. The Flint River receives it at river mile 0.0. Thirteen public land units total 1,088 acres. No survey covers it.
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 46.4–37.5 | 2.0 | cool | Warm transitional stream · medium gradient |
| RM 3.1–0.0 | 1.7 | warm | Warm small river · very low gradient |
MDNR has classified 3.7 of the 48 miles NHD carries for this stream — 8% of it. The typed water splits 2.0 mi cool, 1.7 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 9.8 of the 47.9 mapped miles; 38.1 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.

Stocked, per the MDNR record: Brown trout. The most recent plants are Brown trout at Oakwood Road (Oakland Co., through 2026); Brown trout at Henderson Rd (Genesee Co., through 2021); Brown trout at County Line Rd/ray Road (Oakland Co., through 2021).
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.

And 33 more — the year-round records, mostly: midges, scuds and sculpins, which are in the water every day and are therefore never the news.
4 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.
Kearsley Creek sits in HUC 8 04080204, the Flint subbasin, and drains 111 square miles, Strahler order 5 at the mouth. 79 NHD reaches carry the name for 47.8 miles in total.
