Michigan River Fishing Hatch Chart

Michigan has tens of thousands of miles of rivers that both cold and warm water species of fish call home. Many of them feed on the insects that also live in the river, many of which emerge from a subsurface nymph or larva, to a flying insect that fish feed on surface. It’s this “dry fly fishing” that lures many anglers to the stream to test their skills at fly fishing.

We are truly blessed to have some epic insect hatches, especially in west Michigan that bring fish to the surface in search of floating insects that fish eat. From “blizzard” hatches of caddis and gray drakes, to the elegant emergence of a sulphur and the fly “copters” we call Hex’s, Michigan is rich with insect filled rivers and fish that reside in them.

Below is a chart that outlines what hatches and when. We certainly welcome any calls or emails with specific questions.
