Flowing through Michigan’s Crawford County, the Au Sable River carves a path of pristine beauty, and at Conners Flat Public Access Site, it reveals a fisherman’s dream. This stretch of the Northern Lake Huron watershed teems with wild brook trout, brown trout, and rainbow trout—a gear-restricted stream where nature sets the rules. With a boat launch and shoreline access, it’s a serene spot where the river’s deep heart meets the wild, inviting those who cast for solitude as much as fish.
A River Ruled by Trout
Conners Flat thrives as a trout sanctuary. Wild brook trout shimmer up to 12 inches, while brown and rainbow trout stretch to 20 inches or more, lurking in the river’s depths. The stream’s center runs deep, a challenge for waders who must hug the shoreline’s edges. Designated as gear-restricted, it demands finesse—anglers should consult the Inland Trout and Salmon Stream Regulations in the Michigan Fishing Guide for the latest rules. A boat launch eases entry for those drifting the current, offering a front-row seat to the Au Sable’s cold, clear flow.
This is classic trout water, shaped by decades of conservation and the river’s own untamed spirit.
Nature’s Northern Stage
The Au Sable at Conners Flat is more than a fishing hole—it’s a slice of Michigan’s wild north. Flanked by pines and hardwoods, the river cuts through a landscape that hums with life. Brook trout dart in the shallows, while browns and rainbows hold in deeper pools, their colors flashing against the gravel bed. Beyond the water, the forest rustles with deer and the occasional osprey overhead, hunting the same bounty. It’s a quiet stretch, far from the clamor, where the ripple of the current and the tug of a line set the pace.
