Chris Izworski reporting from Michigan on the current state of the Pine River this Tuesday morning. Late September is the season when serious trout anglers stop talking about crowds and start driving northeast. The Pine River, that fine AuSable tributary flowing through the Huron National Forest in Alcona and Iosco counties, sits in the sweet spot between summer heat and the chaos of fall color tourism. Brown trout are beginning to think about spawning. Brook trout are still willing. And you might have a pool to yourself.

Today the Pine is running at 98 cubic feet per second. That is 128 percent of the historical median for September 29, which puts it near normal for the date. The USGS gauge shows a height of 10.49 feet. The systematic conditions rating is Fair. Fishable. Pick your spots. This is honest language. It means the river is not blown out and not dropping gin-clear. It means you will catch fish if you know where they are and you present something they want to eat.

Flow and What It Means Today

At 98 cfs, the Pine is slightly elevated from its typical late-September baseline of 76 cfs, but well within the normal range. The 25th percentile for this date sits at 53 cfs and the 75th at 106 cfs, so you are just shy of the upper quartile. This is water that has some push to it without being pushy. Riffles will have good current. Pools will be darker and deeper than they would be in true drought. The browns will be holding in predictable lies, not scattered across marginal water. The brooks will be up in the cooler sections.

The forecast shows a 47 percent chance of rain over the next 48 hours, with Thursday bringing an 80 percent chance. That means flow is likely to rise in the next few days. If you are thinking about the Pine this week, do not wait for Thursday.

Hatch Window and Evening Opportunity

This time of year on a northern Michigan freestone, the Blue-Winged Olives are the reliable workhorse. Baetis hatches have started coming off on cloudy afternoons and overcast mornings. Small flies, size 16, and tippets of 5X or 6X. Parachute patterns and Sparkle Duns sit above the water where the fish can see them. If the hatch is heavy, which it often is in September, fish an RS2 or similar emerger just subsurface.

Tonight will turn cool. Patchy fog and a low near 44 degrees. That kind of night can push a Trico spinner fall at first light tomorrow, but that window belongs to Wednesday morning, not today. For this afternoon, watch the golden hour from roughly 5:50 PM through sunset at 7:20 PM. If the sky stays mostly sunny as forecast, overcast conditions may not materialize until evening. Fall Caddis are active in the afternoons and will be skating the runs and riffles. An Orange Elk Hair Caddis in size 14 deserves to be on your leader.

Terrestrials continue to fish well along the banks. Beetles and ants, dropped tight to the grassy margins and undercut banks, will draw strikes from fish that have learned to look up at the shore. Give the fly a second to sit. Let gravity work. A subtle twitch is better than frantic movement.

Access and Strategy

The Pine is accessible from Kings Corner Road and from various Huron National Forest roads near Oscoda. This is public water in a working landscape. The general trout regulations apply. Brown and brook trout share the system. The browns are the ones worth targeting right now in September. They are moving. They are feeding hard before the spawn. A medium-sized brown trout holding in current behind a mid-stream boulder will hit a properly presented fly with conviction.

Fair conditions reward selective fishing. Spend your time in the runs where current speed pushes good oxygen and food. Skip the dead pools. Read the water for the shade lines where browns will position themselves on a day like this. Early morning or evening will always be better than midday in late September, but that does not mean you cannot fish midday. It means you need to be smarter about where the trout are hiding.

The Week Ahead

Today is fishable. Wednesday will be similar, slightly cooler, with that early morning Trico window. Thursday brings rain and higher water. If you have been putting off a trip to the Pine, go today or early tomorrow. By late week, the character of the river will have shifted. It will still be worth fishing, but the light touch and the careful presentation that makes late September so satisfying will become more of a challenge.
