Measured · 54 gauges reporting · 3:23 PM EDT on September 28, 2026
Michigan water is running 51–71°F across 54 gauges reporting in the last 6 hours. 45 are in prime shape — East Branch Salmon Trout River at 51°F, Salmon Trout River at 52°F, Pine River at 52°F, and others below. 8 sit in the 64–70°F transitional band, where the fish are catchable early and should be left alone by mid-afternoon. Escanaba River is the warm end at 71°F. Air holds in the 60s through Thu, and water should hold about where it is.
Every temperature behind the clock on this page is a measurement — USGS water temperature at a real gauge, taken within 6 hours of the reading's own hour. Hours ahead of the last measurement are projected from the hourly air forecast and are labelled as projected. That is also why the lists below are only as long as the gauge network is dense — a river with no gauge on it has nothing measured to report. 1 MI gauges had no reading in the last 6 hours.
Data refreshed nightly, current-hour rendered live — this page carries 24 hours of measured water behind 3:23 PM EDT on September 28, 2026 and 48 ahead of it, and shows the hour you are reading it in.
The bands are the map's own: the same breaks BirdTrout paints water with, so a stream that is green here is green there.
under 64°F — trout are feeding

64–70°F — fish early, keep fights short

Air, not water. Water follows smoothed air with a sensitivity well below one — a spring creek barely feels a hot afternoon and a shallow freestone nearly tracks it — so this table is a direction, and the measurements above are the answer.
30,483 classified stream miles in Michigan, by MDNR designated trout stream type. This is the standing classification, not today's temperature — it is what the water is normally, which is the context the readings above sit in.
