Flow is running at 184 cfs with a gauge height of 1.18 ft at Au Sable Forks — low and clear conditions demand stealthy presentations and fine tippet. Overnight lows dropping into the upper 40s are pulling water temps down nicely, setting the stage for aggressive fall feeding.

Best Time Window
- 7 AM - 10 AM: Midge activity in slow pools and eddies — tight-line or indicator nymph with small midges in the upper column.
- 10 AM - 2 PM: Prime BWO hatch window under mostly sunny skies — work emergers and dries through tailouts and inside bends.
- 6 PM - Dusk: Low light triggers streamer and sculpin action — swing or strip through deep runs and below riffles for fall browns.
Guide's Tip
From the benchAt 184 cfs the Ausable is running low and gin-clear, so leader length and tippet diameter are everything — go to a 12-foot leader with 6X fluorocarbon and approach rising fish from downstream on your knees. Focus your morning hours on midge-sipping trout in the slower pools and tailouts, then shift to BWO nymphs and emergers in the seams as the sun climbs and the hatch builds toward midday. Evening is your best shot at a big brown — swing a sculpin pattern through the deep slots and below the riffles as light drops off the water. With overnight lows in the upper 40s, water temps are trending in the right direction and fish will be increasingly aggressive through the week.
