The river offers some excellent fishing for king salmon and steelhead. Brown trout have been caught in the river too, but they are here in much smaller numbers. The Manistee River is one of the best steelhead rivers you can fish in the midwest. There are good numbers of fish and some very big fish in the river too. The salmon fishing starts getting good in August and runs into October. The steelhead fishing picks up in late fall and runs through the winter into the spring.
