Trout fishing near Marshfield, Wisconsin

Last updated 2026-09-24 · water classified by WDNR

WDNR classifies 75 named streams as trout water within 40 miles of Marshfield, Wisconsin — 393.8 miles of it inside that circle. The most of it is Little Rib River, 30.8 miles out, with 16.8 classified miles that WDNR classifies Class II. The closest is Fourmile Creek at 21.8 miles. A classification is WDNR's statement about the water, not a record of a fish in it and not permission to stand on the bank — check access and the current regulations before you go.

The trout water within 40 miles of Marshfield

Ranked by how much classified water lies inside the circle, and by nothing else. Distance is a straight line to the nearest point of the stream rather than to its middle, because the question is how far you drive before you can park — this app carries no road network and will not print a drive time it cannot compute. A stream that runs out of the circle is counted for the part that is inside it, never for its whole length.

75 named streams clear the circle in all and the 8 holding the most classified water are named. The rest carry less water than something a reader would pass on the way to it.

A stream marked part of the stream carries classified water outside the circle too, and the mileage here is only what is inside it. The thermal class is inferred from WDNR management tier (wild supplemented), and it describes the reaches inside the circle rather than the whole stream.

What WDNR is saying, and what it is not

Every row above is on the list because Wisconsin Department of Natural Resources publishes a trout classification — Class I, II or III — per segment. That is WDNR saying it classifies and manages the segment as trout water, and which of the three classes it puts it in. It is not a record of a fish caught there, it is not a promise about any particular day, and it is not permission to walk to the bank — the land beside a classified stream can be private, and in most of these five states most of it is.

No species are named on this page. Wisconsin Department of Natural Resources classifies the water and does not publish which trout a segment holds, and this site will not put a fish in a named creek on its own authority. The classes above are what the state does say.

Where you can get to the water

Named public access standing on classified coldwater within 40 miles, nearest first. Each of these has a page of its own here, and that page says which list it came from — one of the five agencies, or OpenStreetMap, which is where most of the bridges and two-tracks a trout fisherman actually parks at are recorded. A site being on this list is not a claim about who owns the bank on either side of it, and the water named beside it is the classified reach the site stands nearest to rather than the one it is named for.
