Chris Izworski reporting from Michigan on the current state of the Black River. We’re deep into July on this remote eastern UP brook trout stream, and the season has moved squarely into terrestrial and evening dry-fly territory. The tannin-stained water that defines this river remains cold and dark, which is exactly what the fish prefer, but today’s gauge data is unavailable, so before you load the truck for the drive to the Garnet area, let me walk through what we know and what you should watch for.
What the Lack of Data Tells You
When the USGS gauge readings go silent, you’re left to read the river itself. The Black is a headwater stream, spring-fed and naturally cold, so it doesn’t swing as dramatically as the lower rivers do. That’s actually an advantage. Even without hard numbers, you can expect the water to be clear enough to fish if recent weather hasn’t dumped rain on Schoolcraft County. Check the extended forecast before you leave. Any substantial rain in the next forty-eight hours will push the stream higher and likely muddy it, making the drive a wasted proposition. The good news: July heat and the long daylight hours mean even a minor rise clears quickly on a small stream like this.
Terrestrials Dominate the Midday Hours
Right now, in mid-July, the daytime fishing on the Black belongs to terrestrials. Hoppers, beetles, ants, and crickets are falling from overhanging grass and streamside vegetation into the water. The conventional wisdom about fishing hoppers midday in warm weather applies here, but with one qualifier: on a headwater stream this small and cold, the fish don’t shut down quite as completely during the heat as they would on a spring creek. Still, your best terrestrial fishing happens between 10 AM and 3 PM when the air temperature climbs and insects are most active. Fish close to the banks, especially the grassy undercut sections. A foam beetle in size 12 or a Chernobyl ant in size 10 works reliably. The presentation matters more than the exact pattern. Drop the fly right against the bank, let it sit for a beat or two, then give it a subtle twitch. The strike often comes on the pause.
Evening Dry Flies, Starting at Seven
This is where the Black shines in July. As the sun moves lower, the Sulphur hatch begins in earnest around 7 PM and builds through 9 PM. You want to be on the water by 7:30 PM at the latest to position yourself in the flat, slower sections where the fish rise. Bring a Sulphur Comparadun or Parachute in size 14, and have some smaller Rusty Spinners in 16 and 18 ready for the later stages when the females begin dropping their eggs after dark. The Light Cahill, another evening dry, also appears around dusk on the Black and produces steadily on the flat runs.
Golden hour this evening stretches from 7:57 PM to 9:27 PM, which means you have a solid window of good light for dry-fly work before the Hex hatch potentially takes over. Light tippet is critical for Sulphurs. Go with 5X or 6X and a long, fine leader. These are wild brookies in cold water, and they spook easily. A drag-free drift matters as much as the fly itself.
Night Fishing for Hexagenia
After the evening Sulphurs finish, the Hexagenia limbata, or Hex, begins to emerge. This is a big hatch, and the fish respond accordingly. Listen for the characteristic slurping rises of larger brookies feeding on the surface duns. You’ll want to fish from roughly 10 PM until around 2 AM if you have the patience for it. A headlamp helps, but use it sparingly. The water is dark, the fish are eager, and they’re often right at your feet. Wade slowly, watch the water, and wait for the rise. An Extended Body Hex Dun or Para-Hex in size 4 is the pattern. You can move up to 3X or 4X tippet for this hatch because the fish are larger and less line-shy when they’re in full feed mode at night.
Morning Tricos at First Light
If you’re the type who fishes through the night or returns at dawn, Tricos start their spinner fall as the sun breaks the horizon. The window runs from first light to around 9 AM. It’s classic small-fly, sipping-rise fishing. Tiny CDC Trico Spinners in size 20 on 6X or 7X tippet, cast to individual rising fish, one fish at a time, with patience. You’ll likely hook fewer fish during a Trico fall than during the Hex hatch, but the ones you do connect with will give you the kind of slow-motion presentation that reminds you why you fish small streams in the first place.
Access and Logistics
The Black is accessed via Hiawatha National Forest roads in the Garnet area. It’s remote and lightly fished, which is precisely what makes it worth the drive. Bring bug dope, wade carefully, and respect the stream.
