Lake-run brown trout Run in Wisconsin

Salmo trutta, coaster brown, on Superior — 13 Wisconsin rivers on this map carry a run of it, Lake Michigan and Lake Superior. 13 of them are inside a window as of 1 October 2026.

Wisconsin carries Salmo trutta out of two lakes on 13 rivers, and the two shores keep different calendars. The Lake Superior rivers hold the earlier window, September through November, and the Lake Michigan rivers open in October and close in November; both peak in October. Those windows are month-grained, which is as fine as the guidance goes. The Superior side also holds the long corridors — 70.2 miles on the Nemadji, 42.6 on the Amnicon, 40.4 on the Bois Brule — against 40.7 on the Sheboygan and 29.8 on the Milwaukee.

The fish is buttery-flanked with black and red spots and no spotting on the tail worth the name, which is the mark that separates it from everything else in the run at the net. Three to fifteen pounds. It runs with the autumn steelhead and behind the salmon, is the most nocturnal fish in the corridor, and many hold over into February and March. On Superior it is called a coaster brown.

Where these rivers are

13 run rivers on 2 shores, drawn one shore at a time and each river in the colour of its own run stage today. One frame over all of them would be mostly open water.

Drawn 1 October 2026. The ground is the subbasin mesh the app scores in, so the coastline is where the mesh stops rather than a separate shoreline; the mark at each river is its mouth, drawn for every river including the handful whose whole run corridor is under a mile and has no line to show.

Where it runs, and when

Ranked by the rivers the staging estimator models first — the sixteen systems with a USGS temperature gauge behind them — then by corridor miles. Neither is a measure of fishing, and nothing on this page ranks a fishery.

Tackle and tactics

Regulations

Great Lakes tributary rules are not the inland trout rules, and they differ by river and often by reach. Wisconsin's regulation summary is here; the state's own guide is the regulation.
