USGS gauge — live water temperature

Water temperature — the colour of the river, and of every dot on it

58 64 70

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.

Water temperature right now

Live from the USGS — every pill above is live, so the numbers you are reading are the latest continuous readings at each gauge. Provisional and unreviewed, as all real-time data is. If that fetch cannot happen — you are offline, or the USGS is down — the pills fall back to the last value we cached, 30 September 2026, 13:43 UTC.

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, 04121660.

The character of the water

Thermal classification

Each gauge carries a July mean built from its own daily record — 8 Julys, 2019–2026, measured rather than modelled. A July mean is what decides which of the four bands a stretch of water belongs to, because July is when a trout river either holds or does not.

Every gauge sits at the bottom of its segment, so each number is the warm end and the water above it runs colder. ±1.72 °F on the fit.

The lake run

The Muskegon River is a Lake Michigan tributary with 52.0 miles of run corridor on it — salmon, steelhead and lake-run brown trout, on their own calendar and under their own rules. Run timing, species and access on the Muskegon River →

Regulations

MDNR trout stream types, as designated. Types on file cover 91.7 of the 231.2 mapped miles; 139.5 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.

Creel across all types: 5 fish, with no more than 3 trout 15“ or greater. Zero (0) Arctic Grayling. Tackle: Artificial lures and all types of natural bait may be used.

Fishable reaches

River miles are measured above the mouth, along the mapped mainstem. The reach breaks are the gauges, which is also how the temperature model divides the river.

20 mapped access sites on the mainstem: 6 walk-in, 14 boat or canoe launches. Source: MDNR.

Historical July mean

The measured record behind every temperature band on this page: the mean of the daily means for July, at each gauge, over the years USGS has one.

Hatches on this water

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.

And 39 more — the year-round records, mostly: midges, scuds and sculpins, which are in the water every day and are therefore never the news.
