Being free myself from the chains of labor last Friday, and surmising that the day might provide some first-rate fishing, I made a day trip to the Au Sable.
I planned to spend most of the day on the big water below Mio, but I remembered heavy trico hatches on the north branch over a labor day weekend a few years ago, so I went there first. My car thermometer read 41 degrees when I pulled into an access above twin bridges just before 9AM. Tricos did come, around 10:15, but the hatch was very thin. Feeding activity was lighter than when I'd fished the same stretch in July, and the fish that showed were exceptionally spooky. I put down the first two pods of fish I cast to after two or three casts. I approached a third on hands and knees, setting up behind a large sand ridge that ran between a weedy backwater and the run where the fish were rising. It was difficult to get a good drift over the fish, since there wasn't room for a backcast that would load the rod (even my whippy 4 wt) and generate enough forward power straighten the leader. Kneeling and catching the water with the elbow of my rod arm when I cast didn't help with accuracy either. But I did manage a few good drifts and didn't put the fish down with the bad ones. During the twenty or so minutes the hatch lasted, I managed a couple of smaller brook trout and a shiner.
I headed downstream to Mio for the afternoon and evening.
Bob Linsenman told me that white fly soft hackles were still the ticket, so I hopped downstream from access to access fishing one in tandem with other nymphs or emergers. The midday action wasn't red hot, not even as good as it had been the Friday before. I took three planter rainbows, lost a few others.
That wasn't the most regrettable part of the afternoon, though. While fishing in front of the Davis rest area, I heard a roaring coming from upstream and I turned around to see two jet skis rounding the bend. They weren't moving fast but they're kicking up a wake that could easily (and possibly did) swamp a canoe and making enough racket to drown out every drunken tuber on the river. After they passed a cloudy ribbon trailed along the river's edge for almost five minutes, erosion from their wake breaking on the bank. Soon they were headed back upstream: more noise, more silt. I hope jet skiing isn't becoming popular on those waters.
Around 4:30 a nice BWO hatch began and fish began feeding avidly. Over the next hour and a half I caught about 10 trout, 10-14" long. When the bwos faded, I went to the McKinley bar for a quick supper and got back on river a bit before 7:30. The white fly hatch began shortly, and using an emerger, I took 8 or 9 trout about like those I'd caught on olives. When they stopped hitting the emerger, I looked down for spinners and saw none.
Last year on a superb night of white flies, I switched to a spinner pattern far too early and missed a lot of trout I should have taken, but didn't switch back because I didn't want to have to re-tie the spinner on in the dark. Last Friday I decided to keep the emerger on until the spinner fall was obviously in progress, but a succession of trout ignored it. When I did see the first spinner, I immediately went to change flies, but I fumbled tieing on the spinner in near darkness (there's a stretch between twilight and full dark where the vest light is of limited help). I only heard about two rises once I was ready to go, and my casts in their direction produced nothing. But having done well earlier, my regrets were mild.
I sometimes feel guilty about these day trips, burning a lot of money and gas for a single day of pleasure. Sometimes I don't even catch much. But this one was worth every penny and every pound of C02.
