Measured · 3 gauges reporting · 3:23 PM EDT on September 28, 2026
The Wolf, the Popple, the Pine and the freestone rivers of the north.
Northwoods water is running 60–63°F across 3 gauges reporting in the last 6 hours. 3 are in prime shape — Popple River at 60°F, Namekagon River at 61°F, St Croix River at 63°F. Air holds in the 70s 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.
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
Nothing in this band right now.
over 70°F, or under 40°F — leave it alone
Nothing in this band right now.

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.
4,751 classified stream miles in Northwoods, by WDNR trout classification. 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.
| Class | Miles |
|---|---|
| CLASS II | 2,083 |
| CLASS I | 2,018 |
| CLASS III | 651 |
