Chris Izworski, reporting from Michigan on the current state of the East Branch Au Gres, has to lead with the hard truth: this river is not fishable today. The USGS gauge shows 52 cubic feet per second at the Andrews Road crossing near Alabaster, which runs at 173 percent of the historical median for October 3rd. That’s well above flood stage. The water is high, off-color, and moving fast enough that the fish have buttoned up. If you were thinking about making the drive northeast to Arenac and Iosco counties this morning, save your gas.
The East Branch is a freestone stream, which means it responds directly to precipitation and snowmelt. Right now it’s responding like a fire hose. When a freestone river runs nearly twice what it should for this date, the trout stop feeding predictably. They tuck into the deepest holes and slowest water they can find, which means you can cast yourself hoarse in the runs and riffles and watch your offerings swing through empty water. The Michigan Trout Report rates conditions here as Tough, which is a professional way of saying don’t waste your afternoon.
What the Next Few Days Hold
The good news arrives with the forecast. Rain chance over the next 48 hours sits at 19 percent maximum, and the National Weather Service is calling for sustained clear skies through Tuesday. More importantly, there is no significant precipitation expected in the three-day window. Flow is likely to stabilize and drop, which means the river will start fishing its way back into reason by Monday or Tuesday.
Sunday brings 68 degrees and a 19 percent rain chance, with overnight lows dropping to 45 degrees. Still probably too high and too warm for good fishing. But Monday looks cleaner: 61 degrees, zero rain chance, and a low of 41 degrees. That overnight chill will help the fish. Tuesday follows the same pattern, crisp and clear, with a 60-degree high and no rain in sight. If the flow trend holds stable as the forecast suggests, Monday afternoon or Tuesday morning would be the window to mark on your calendar. The East Branch cold upper sections hold browns that will eat during midday fall conditions once the water settles.
October Fishing When Conditions Are Right
This is the season for different tactics. Fall Caddis are active in the afternoons, skating orange Elk Hair Caddis number 14s across the runs and riffles. There are also Blue-Winged Olives around, the fall Baetis tricaudatus strain that emerges midday on cool, cloudy conditions. Small flies tied to long fluorocarbon tippet, 5X or 6X, work the emerger phase just subsurface. Parachute BWOs in size 16 and RS2s in 18 are standard. Midges dead-drifted under an indicator in the slow pools and eddies will take fish even when nothing else does. Mercury Midge and Zebra Midge in size 20 are reliable.
Streamers belong in your rotation too. October browns are thinking about spawning or the spawning they just completed. A small streamer stripped through the deeper water, particularly in the early morning or the last light, can trigger strikes.
The golden-hour window this evening runs from 5:43 PM through sunset at 7:13 PM. On a normal October day with this kind of light and cool air, that would be prime dry-fly time. Not today. The water is too aggressive. The fish are not in the mood to rise. Better to use that time to scout the stream, learn where the cuts and the deeper holes are, and plan a return trip when the gauge cooperates.
When to Come Back
Check the live gauge data at https://michigantroutreport.com before you drive. The Andrews Road access near Alabaster is your entry point. When you see flow settling back toward the 30 to 33 cubic feet per second range, the river will be worth fishing again. That’s probably Tuesday. Until then, this is a look-ahead situation.
