Rivers / Upper Peninsula

Salmon Trout River

Often cited as the only remaining stream on Lake Superior's south shore with a significant coaster brook trout population; adult numbers are up about 70 percent since 2002 but remain small, protected by an 18-inch, one-fish rule and a shortened season ending August 14. Coaster migrations begin in mid-July. Two USGS gauges report water temperature. No hatch chart was located.

Hatching in August

Eggs in the drift

In August no eggs are in the drift here. Next up: brook trout eggs. Spawning follows water temperature rather than the hatch offset, so these months do not shift.
