Chris Izworski, reporting from Michigan on the current state of the Black River, has a straightforward assessment this Monday in late April: the river is fishable today, but barely. And that’s not a complaint. It’s the reality of early spring on a Western UP freestone stream in snowmelt season.
The Black River near Bessemer is running at 1120 cubic feet per second this morning. That’s 111 percent of the median flow for April 20th, which means it’s running a touch above normal for the date. Not blown out. Not unwadable. But definitely carrying snowmelt from the Porcupine Mountains, and the water temperature data isn’t available from the gauge today, which usually means the DNR hasn’t updated yet or conditions are still fluctuating with the daily warming cycle.
Here’s what matters: the flow is manageable. The systematic conditions rating this morning is “Fishing Well,” which on a river like this means the water is high enough to push fish off the bottom and into feeding lanes, but not so violent that you’re wading blind or losing flies every third cast to hidden rocks. The gauge height of 4.91 feet is in the zone where patient work in the slower water pays dividends.
What’s Actually Hatching Right Now
This is the week the Hendricksons start to show in Michigan, and the Black River will get its share. But don’t expect a blanket emergence just yet. The Hendrickson hatch, classic dry-fly fishing that it is, needs stable water temperature and overcast afternoons to really trigger. Right now you’re in the window where midges and little black stoneflies are your bread and butter, supplemented by Blue-Winged Olives on overcast periods and the occasional rise to caddis.
The midge fishing is steady. Fish them dead drift under an indicator in the slower pools and eddies, tight to the bottom. Mercury Midges or Zebra Midges in size 20 will work. Little black stoneflies are crawling out along the banks to hatch, so a dead drift of a Little Black Stonefly dry in size 14 along undercut banks in the morning will produce takes. In the riffles, nymph it with a Black Stonefly Nymph size 14.
The early brown stoneflies and grannom caddis are present now too. Swing a wet fly or nymph through the riffles on the rise. An Elk Hair Caddis in brown, size 14, can be skittered across the surface once the water settles enough to see a clear rise form. The X-Caddis in size 14 will work in the film if the fish are selective.
The Real Question: Should You Drive North Today
Yes, if you’re within striking distance and the drive doesn’t wreck your week. The river is fishable and holding fish. Access is available through the Black River Harbor Recreation Area and multiple county road access points, so you won’t struggle to find water to wet a line.
But here’s the honest angle: you have a long evening window ahead. Sunset is at 8:54 PM, which means golden hour dry-fly fishing runs from 7:24 PM through dark. That’s your best shot at dry-fly work if the Hendricksons start to pop or if the caddis activity intensifies in the last two hours of daylight. Plan for that window.
The water is still cold. The snowpack in the Porcupine Mountains is still releasing. Watch the forecast for the next three to five days. If a warm front moves through without heavy rain, the river will clear and warm slightly, and the hatch timing will accelerate. Right now, the conditions are near normal but worth respecting as high-water spring fishing, not as the stable hatch window you’ll see by late May.
Bring small flies. Use long tippet on the dries, especially the midges and BWOs. Fish the nymphs where you can see the bottom, and don’t be afraid to work the slower water where bigger brookies hold tight during runoff.
