Chris Izworski, reporting from Michigan on the current state of the Pere Marquette this Tuesday morning in mid-May.

The Pere Marquette is running roughly 850 cubic feet per second at the Scottville gauge today, which sits a touch above the historical median for the second week of May. That puts it in the range a working PM angler wants to see: elevated enough to push wild browns out of their winter lies, low enough to wade the gravel runs in the flies-only stretch without fighting the current to do it. Water temperatures are climbing through the high forties into the low fifties by mid-afternoon, which is exactly the band where the fish start to look up.

The clarity is honest. The PM is not running clear in the strict sense, the way it does in August, but it carries the slight tea color of a Manistee National Forest river that has just finished moving its snowmelt out of the upper reaches. You can see your fly. The fish can see your fly. That is what matters.

The Window This Week

The next three days look like the window of the week. Today and tomorrow stay dry across Lake County. Wednesday warms into the mid sixties with light wind, which will concentrate hatch activity and bring fish to the surface in numbers we have not seen consistently since the season opened. Thursday brings a chance of evening showers, which on a river like the PM is rarely a problem and often a benefit, since light rain through a sulphur emergence will keep fish on the feed past the usual cutoff.

Friday and Saturday bring a stronger weather system through the western Lower Peninsula. Plan around that. If you have a choice between fishing Wednesday and fishing Saturday, Wednesday is the cleaner call.

What is Emerging Now

The Hendrickson hatch is winding down on the lower river but still has life in the cooler upper reaches above Baldwin. If you are fishing above the Forks, a Hendrickson Dry in size 12 or a Red Quill will still take fish in the afternoon rise lanes. Below the Forks, the Hendrickson is largely finished and the river is moving into sulphur season.

The sulphurs are the event hatch right now. The emergence typically peaks between seven and nine in the evening, and on a warm calm day like Wednesday looks to be, you should see fish committed to surface feeding for the full two hours. A Sulphur Comparadun or Parachute in size 14 to 16 is the right starting point. When the heaviest activity hits and fish go selective, switch to a film emerger and fish on a long 6X fluorocarbon tippet. The PM has educated fish, and the difference between a hookup and a refusal is often the last twelve inches of leader.

Caddis are working across the river all day. Grannom caddis in the morning, light tan caddis in the afternoon. Skate an Elk Hair Caddis in size 14 through the riffle heads, or fish a soft hackle wet fly on the swing through the same water. The PM rewards an angler who is willing to fish three different methods through a single day.

Where to Go

The flies-only water from the M-37 bridge downstream to Gleason’s Landing is in good shape. The classic runs at Claybanks, Whiskey Creek, and the lower reaches above the Indian Bridge takeout are all fishing. Wild browns from twelve to eighteen inches are realistic. The occasional larger fish will come from the deeper bend pools, especially at the seam where the current meets the slower inside water.

If you want quieter water, the upper river above the M-37 bridge fishes well for smaller wild browns and the occasional brook trout in the headwater tributaries. The crowds thin out fast as you move upstream from Baldwin.

The Practical Read

This is a week to be on the PM. The flows are honest, the hatches are stacking, and the weather supports a sustained fishing window. If you can take a day off, Wednesday is the one. If you are limited to a weekend, plan to be on the water by mid-afternoon Saturday and fish through the evening sulphur emergence regardless of weather. The Pere Marquette in mid-May with sulphurs working is one of the genuine reasons to live in Michigan as an angler.
