Spring arrives differently on different rivers. On the Muskegon and Pere Marquette, it means thousands of chrome steelhead pushing upstream from Lake Michigan — some of the most powerful fly fishing in the eastern United States. On the Au Sable and Boardman, it means high, cold water slowly warming toward the magic temperature that triggers the Hendrickson hatch and the first rising trout of the season. Spring is the season of transitions and it demands patience, but the rewards — a fresh steelhead in April, a brown rising to a Hendrickson on a calm May afternoon — are what Michigan fly fishers plan all winter for.

Spring dates book fast on the PM and Muskegon. The steelhead run peaks mid-April through early May in a normal year, though a cold spring can extend it well into June. Book guided steelhead trips by February — PM guides like Batcke's and Feenstra on the Muskegon fill before the holidays.
Summer is the heart of the Michigan fly fishing season. June is dominated by the Hex hatch — the most famous and most anticipated fishing event in the state — and the Brown Drake and Sulphur hatches that bookend it. July brings Trico spinners on the Au Sable in the early morning and terrestrial fishing in the afternoons. August is the lean month — midday heat pushes fish deep and the fishing concentrates in the early morning and after dark. The rivers are beautiful and the fish are selective. Summer requires the most skill of any Michigan season and delivers the most memorable fishing.

Fall is arguably the most visually spectacular season on Michigan's rivers. The hardwoods of the Jordan Valley, the Au Sable corridor, and the Upper Peninsula turn amber and red by mid-October, and the rivers are full of fish. Chinook and Coho salmon push into the Manistee, Pere Marquette, and Muskegon from September through October. Resident brown trout feed aggressively ahead of their November spawn. Fall steelhead begin arriving in October. And the Mahogany Dun and BWO hatches bring fish to the surface on cool overcast afternoons — some of the most consistent dry fly fishing of the year.

Best Fall Rivers
Fall steelhead on the Pere Marquette and Muskegon typically begin in earnest by mid-October and run through November. Water temperatures in the low to mid 40s are ideal. Fall steelhead are harder to catch than spring fish — they're not motivated by spawning and require more precise presentations — but they are among the most rewarding fish of the year.
Winter fly fishing in Michigan is not for everyone — but for those who embrace it, it offers something no other season can: absolute solitude. The tailwaters below Croton Dam on the Muskegon and Tippy Dam on the Lower Manistee remain open and fishable year-round, regulated by the consistent cold temperatures released from the impoundments above. Resident brown trout are present and catchable throughout winter. BWO hatches occur on warm winter afternoons when air temperatures climb into the low 40s. And there is no crowd, no boat traffic, no competition for water. Just the river and the fish.

Best Winter Rivers
Winter fly fishing on Michigan rivers is genuinely challenging — cold hands, icy guides, and slow-moving fish require patience and preparation. But the Muskegon below Croton Dam on a 42°F overcast day in January, with a BWO hatch coming off and brown trout rising quietly in a flat pool, is one of the most peaceful experiences fly fishing has to offer. Bring a thermos.
