Chris Izworski, reporting from Michigan on the current state of the Tahquamenon, must begin with a straightforward observation: the river is running high today, and if you are thinking about making the drive north to the Paradise area, you should know what that means before you leave.
The USGS gauge is reporting 6080 cubic feet per second. The historical median for this date is 3180 cfs. That puts today at 191 percent of normal, well into the 75th percentile range for April. The gauge height stands at 9.92 feet. This is not a river you want to wade today.
The Spring Runoff Reality
The Tahquamenon, like all the great rivers of the Eastern Upper Peninsula, lives within the rhythm of the snowpack. April is the worst month for predictability. The deep snow that sits in the UP watershed all winter begins to release now, and it releases with volume. Yesterday’s rain did not help. The water is high, the current is fast, and in the riffles and runs where you would normally fish, the force of the flow will make safe wading nearly impossible for most anglers.
This is not a judgment. It is simply what the numbers tell us. The Tahquamenon is famous for many things, not least the tannin-stained falls that draw visitors by the thousands, but in mid-April, it is also famous for being temporarily unfishable, regardless of the hatch calendar.
What Is Hatching Right Now
The Hendrickson is coming. It always comes in mid-to-late April, and yes, the Tahquamenon has them, typically emerging in the afternoon window between 2 and 4 p.m. under good conditions. You can fish Hendrickson nymphs in the riffles beforehand, using a #12 pattern, dead drifted along the bottom. The dry fly fishing, when conditions allow, is the kind of classic early spring stuff that reminds you why you fish at all.
Before that major hatch arrives in full force, the smaller insects are already on the water. Midges are present in the slower pools and eddies, and you can take fish on a Mercury Midge or Zebra Midge in #20, dead drifted under an indicator near the bottom. Little Black Stoneflies are crawling out along the banks, and nymphs in #14 will work the riffles. The Baetis are emerging too, small and delicate, best approached with 5X or 6X fluorocarbon and emerger patterns like the RS2 in #18.
Caddis are also starting to show. Early Brown Stoneflies will skitter on the surface, and you can swing a Hare’s Ear Nymph in #12 through the riffles or try skating a brown Elk Hair Caddis. Grannom Caddis should be active soon as well, and the skitter technique on an Elk Hair Caddis #14 or X-Caddis #14 can be effective when the water allows you to fish it.
When to Make the Drive
Watch the gauge at USGS before you commit to the drive. The Tahquamenon will drop as the runoff cycle continues through late April and into May, but right now it needs time. Target a flow closer to 4000 cfs or lower if you want to wade safely and fish the water properly. The state park access around Paradise will still be there when conditions improve, and the fish will not go anywhere.
If you do make the trip in the next few days despite current conditions, focus on the slower water. Eddies behind boulders, the slack water along the banks, and the deeper pools will hold fish that have moved out of the main current to rest. Fish small nymphs and midges in these zones. A good indicator rig will let you work the deeper pools without the constant battle against the force of the runoff.
The Tahquamenon is one of the UP’s great rivers, and it holds brook trout in the upper watershed and steelhead in the lower reaches. It is worth the wait for better conditions. Check the gauge, trust what it tells you, and plan accordingly.
