Chris Izworski, reporting from Michigan on the current state of the Menominee River this Monday morning in mid-May.

The Menominee is running at 3,280 cubic feet per second today, which puts it near the historical median for this date. That’s worth saying plainly: after weeks of watching UP rivers blow out and turn chocolate with snowmelt, this is a river that’s settling into workable shape. The gauge height sits at 7.9 feet. For a large border system like the Menominee, which spends much of spring in the grip of the UP snowpack release, “near normal” translates to fishing that’s honest and worth considering.

The weather forecast, though, is the governing detail. A 96 percent chance of rain arrives tonight and builds through Tuesday. When rain of that magnitude hits a river that’s already running near median flow, the trajectory is upward, sometimes sharply. Plan on the Menominee rising over the next thirty-six hours. That doesn’t mean impossible, but it does mean you’ll be managing higher water and muddier conditions if you fish today or tomorrow.

The Case for Waiting Until Wednesday

Wednesday afternoon looks like the real window. Rain drops to a 15 percent chance. The day high reaches only 56 degrees, which will keep water temperatures stable and hatches concentrated. By then, most of the new runoff will have moved through the system, and you’ll be dealing with a river that’s slightly elevated but clearing, rather than a river still in the process of being fed by fresh rain.

If you’re planning a drive from the lower peninsula or even from further south in Wisconsin, Wednesday is the day to target. You’ll fish fewer hours, but you’ll fish clearer water with more predictable conditions.

What’s Emerging Now, and What to Expect

We’re at that sweet part of May when the Menominee wakes up across multiple hatches. Hendricksons are moving through in the afternoons, typically peaking between two and four o’clock. The standard Hendrickson Dry in size 12 or a Red Quill will take fish from the rise lanes in the flatter sections. Nymph the riffles in the early morning with a Hendrickson Nymph before the emergence really gets going.

The caddis are building now too. Early brown stoneflies and grannom caddis are both active. Swing a wet fly or nymph through the riffles, or try skating a dry fly like an Elk Hair Caddis in brown, size 14, across the surface to trigger strikes.

The sulphurs are the event hatch to watch for on the Menominee right now. The emergence typically runs seven to nine in the evening, which means you’ll have a solid two-hour window of golden light starting around 7:39 PM tonight. If conditions were better, the sulphur hatch would be the reason to be on the water. Fish the rise lanes in the flat sections with a Sulphur Comparadun or Parachute in size 14. When the heaviest activity hits, switch to an emerger pattern and work the subsurface with light pressure and long, fine tippet. A 5X or 6X fluorocarbon will be necessary for selective fish. Spinner falls follow after dark, if you’re willing to fish blind with small rustcolored spinners.

Blue-winged olives will show up on overcast stretches too, which today’s mostly sunny conditions won’t encourage much. But if clouds build this afternoon ahead of the rain, watch for them.

Access and Regulations

The Menominee is a boundary water between Michigan and Wisconsin, which means you need to understand regulations for both states before you fish. That’s non-negotiable. Access points around White Rapids Dam and the US-2 crossings near Banat are the logical starting places for most anglers. Check current access conditions before you drive, and verify the specific regulations for the section you’re planning to fish. A boundary water requires more homework than a straightforward Michigan stream, but it’s worth it.

The brown trout, steelhead, and brook trout in the system are a serious draw, and May is one of the best months on any Michigan river. But that draw only translates to a good day if you’re fishing conditions that favor it.

Plan for Wednesday. Watch the gauge and the weather between now and then. The Menominee will be worth the drive when that window opens.
