25 mapped river miles, draining 51 square miles across Lake county, in the Pere Marquette-White subbasin watershed. No gauge stands in it; the nearest is 17.6 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 17.6 miles away, at Muskegon River At Big Rapids — 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: 04121650.
A fourth-order stream of 25.4 mapped miles entirely within Lake County, 18.1 feet wide at the median, draining 51.41 square miles to the Pere Marquette River. MDNR types only 4.4 miles, 17 percent of the length: 2.0 miles Cool of the Warm transitional stream type with high gradient near the top, and 2.4 miles Cold with medium gradient from river mile 17.5 nearly to the mouth. Those classes describe the valley segment rather than the water, and no gauge sits on this branch; the nearest is 17.6 miles away. Type 1 regulation covers 23.1 miles, open from the last Saturday in April through September 30th, with August 1 to November 15 terminal gear restricted to single-pointed hooks and jigs no more than half an inch point to shank, or treble hooks no more than three-eighths of an inch on artificial lures. Two access sites, both launches. Stocking of brook, brown and rainbow trout ended in 1999.
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 24.4–21.4 | 2.0 | cool | Warm transitional stream · high gradient |
| RM 17.5–0.1 | 2.4 | cold | Cold stream · medium gradient |
MDNR has classified 4.4 of the 25 miles NHD carries for this stream — 17% of it. The typed water splits 2.4 mi cold, 2.0 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 23.1 of the 25.4 mapped miles; 2.3 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 2022 at Pere Marquette River, Lake County, in a channel averaging 54.31 feet: brown trout, chinook salmon, coho salmon, rainbow trout, at 2,875 trout per acre and 189 pounds per acre. MDNR strata: medium, great lakes accessible, wild trout; regulation at the station, gear restricted.The station has been surveyed in 30 years since 1973.
Stocked, per the MDNR record: Brook trout, Brown trout, Rainbow trout. The most recent plants are Brook trout, Brown trout at Section 14 (Lake Co., through 1999); Brook trout, Rainbow trout at 64th Avenue (Lake Co., through 1995).
53 insects are recorded from northern 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.
