20 waters in the Grand watershed, Michigan, have a page here, the largest of them Grand River, Flat River and Fish Creek. June, July and August carry the most recorded hatches, 19 insects in June, 21 insects in July and 18 insects in August. In range: 8 blocks of public land with a page of their own, 8 state-forest campgrounds and 5 fly shops. Everything below is measured or published — no ranking on this page is ours.

Assembled, not written: the days are the largest waters in range, longest first, and each one carries the nearest site in Michigan's own access file — measured from the middle of the water, so it is a place to start looking rather than a landing on that river. Fish them in whatever order the weather gives you.

State-forest and state-park campgrounds from Michigan's own file. This site holds no hotel or motel data and does not pretend to: what it can tell you is where the public ground is.
From OpenStreetMap and a curated list, across all five states on this site. Call before you drive — a shop in a file is not a shop that is open.
