# Michigan Trout Weekly Rollup: June 28, 2026

Chris Izworski, reporting on the state of Michigan trout water for the week ending Sunday, June 28, 2026.

The rivers are settling into their summer rhythms now, flows drawing down after the spring push, water temperatures rising into the mid-sixties through the afternoons. This is the transitional week, the moment when the sulphur spinner falls lose their grip on the early evenings and the bigger nocturnal emergences begin to assert themselves. Brown drakes have started on some systems. Hexagenia limbata will show any day now on the right water. The state’s trout are keyed to surface opportunity after dark, which means planning your day around the last two hours of light and the first hour beyond it. Mornings remain quiet, useful mainly for nymphing or streamer work in the deeper slots. By midday the fish have pulled into the shade.

Northern Lower Peninsula

The Au Sable remains the focal point, and for good reason. Flows at Mio are holding near 450 cubic feet per second, gauge height at 2.1 feet, which is manageable and clean. Sulphurs are still coming off sporadically between 8:00 and 9:00 p.m., spinner falls around 9:15 p.m., but the real anticipation is for Hex. Wadeable stretches from Wakeley Bridge down through Burton’s Landing are seeing evening Isonychia, size 10 and 12 slate-winged duns that fish well to a Dun Variant or Iso Comparadun. The Manistee is running clear at 1,100 cubic feet per second near Sherman, temperature range 62 to 67 degrees depending on time of day. Caddis remain reliable through the riffles at dusk. The Boardman, closer in to Traverse City, is fishable but warm, best early or late. If you are committing to one river this week in the north, fish the Holy Waters stretch of the Au Sable from Stephan Bridge downstream. Carry sulphur spinners in size 16, Isonychia dries in size 10, and a couple of Hex patterns in size 6 just in case. You will not need them until after full dark, but you will want them in the box.

Western Lower Peninsula

The Pere Marquette is running at 650 cubic feet per second at Scottville, gauge at 3.8 feet, which puts it in ideal summer shape. Brown drakes have begun in earnest above M-37, particularly in the long glides upstream from Bowman Bridge. Emergence starts around 9:30 p.m. and the fish are looking up. This is wet-fly and soft-hackle water if you fish the hatch itself; dry fly if you wait for spinners after dark. A Hare’s Ear Soft Hackle in size 10, swung through the tailouts, will take fish during the emergence window. The Betsie is clear and cool, 58 degrees in the upper reaches, sulphurs still showing near Kurick Road around 8:45 p.m. The Little Manistee is low but productive for those willing to walk above Nine Mile Bridge, where the canoe traffic has not yet saturated the banks. Hendrickson nymphs size 14 and small caddis larvae will work subsurface through midday. If you fish western Michigan this week, commit to the Pere Marquette above Gleason’s Landing after 9:00 p.m. Bring brown drake wet flies, a headlamp, and patience. The spinners will come.

Upper Peninsula

The U.P. rivers are cold, clean, and underutilized. The Fox near Seney is running at 180 cubic feet per second, temperature hovering near 56 degrees, which is pristine summer trout water. Sulphurs are still active here, trailing the Lower Peninsula calendar by a week or more. Expect duns from 8:30 to 9:15 p.m., spinners just after. This is dry-fly water in classic form: long glides, selective fish, technical presentations rewarded. The Two Hearted, farther east, remains cold and steady, ideal for swinging soft-hackles or stripping small streamers through the deeper runs. Caddis in size 14 to 16 work well in the pocket water. The Escanaba system, often overlooked, is fishing well for those who know the access points below Boney Falls. Attractor dries, Stimulators in size 12, will raise fish through the broken water during daylight hours. For a specific Upper Peninsula recommendation: fish the Fox River above Seney in the late evening with sulphur spinners in size 16 and a fine tippet. The fish are educated but willing. You will have the river largely to yourself.
