Fly: White Wulffs & white spinners #12–14 at last light.

Documented on Ohio's Great Miami, Stillwater, and Ohio River; likely but not formally documented on these exact streams — if you see white bugs at dusk, this is it.

Timing compiled from regional guide & hatch-chart sources — local conditions shift it by a week or two either way.

A State & National Scenic River and one of the Midwest's most biodiverse streams (~40 mussel species, several endangered darters). Please catch-and-release smallmouth and tread lightly on the streambed.

General guidance from seasonal & water-temp patterns — not a guarantee. Always check current Ohio fishing regulations and limits.
