St. Clair weekend fly fishing trip

6 waters in the St. Clair watershed, Michigan, have a page here, the largest of them Black River, Belle River and Mill 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 3 fly shops. Everything below is measured or published — no ranking on this page is ours.

The water

Water MilesJuly mean

Belle River 73.8 —
Mill Creek 33.7 —

Stocks Creek 2.4 —
Black River Canal 1.1 —

Ordered by mapped length. July mean is measured at the USGS gauges standing in each river; a dash means no gauge on it reports temperature.

A 3-day plan

1

Black River

No site in the state's access file falls within twelve miles of this water's centre, so the way in is public ground and road crossings.

2

Belle River

No site in the state's access file falls within twelve miles of this water's centre, so the way in is public ground and road crossings.

3

Mill Creek

No site in the state's access file falls within twelve miles of this water's centre, so the way in is public ground and road crossings.

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.

Recorded from southern lower Michigan, earliest first. The year-round records sit at the bottom because they are true and they are not news.

Public land in range

Blocks of ground with a page of their own, nearest first. Ownership from PAD-US as Michigan publishes it.

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.

Fly shops

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.
