Cast Deep on Michigan's Greatest River
Stories, ideas & perspectives — thoughtfully written, beautifully told.
Ask any guide who's spent serious time on the Au Sable why they almost always fish two flies, and the answer goes a lot deeper than 'covering more water.' Tandem rigs aren't just a tactical shortcut — they're a whole philosophy that reshapes how you cast, read a river, and think through a problem. We dug into the mindset behind the method with some of the folks who know this river best.

02 Most anglers pack it in when the temps drop, and that's exactly why winter on the Au Sable is worth showing up for. Bigger browns, empty runs, and surprisingly active hatches make cold-weather fly fishing one of Michigan's best-kept secrets. Here's what you need to know to make it happen.
03 Fishing two flies isn't just a gear trick—it's a completely different way of thinking about the river. On the Au Sable, where conditions shift by the hour and trout can be maddeningly selective, committing to a two-fly rig forces you to ask better questions, cover more water column, and stay in the game when a single pattern just won't close the deal.
04 While most fly fishers are packing away their waders after Labor Day, a quiet group of in-the-know anglers is heading to the Au Sable for what guides here call the best fishing of the year. Cooling water, thinning crowds, and a whole new insect calendar make September and October something special. Here's how to make the most of it.
05 Most first-timers on the Au Sable spend half their trip casting to empty water. Not because the fish aren't there—they absolutely are—but because reading a new river takes a framework most people never get. This guide breaks down the Au Sable's hydrology in plain terms so you can stop guessing and start finding fish from day one.
06 You don't need a carbon fiber rod that costs more than your truck payment to catch fish on the Au Sable. The right entry-level setup — chosen carefully — will get you on the water and performing well without the financial hangover. Here's an honest breakdown of where to spend, where to save, and what actually matters when you're just getting started.
07 The Au Sable doesn't fish the same way twice, and a big reason for that is what's hatching beneath the surface at any given time. From the first Hendricksons of April to the quiet Baetis falls of October, knowing what bugs are on the water — and when — is the difference between a slow day and a memorable one. This guide breaks it all down so your fly box is ready before you ever pull off M-72.
08 Spring on the Au Sable is a moving target — literally. Water levels climb, color shifts from gin-clear to chocolate milk, and the flies that crushed fish all summer suddenly get ignored like last year's hatch chart. Here's how to read what the river is telling you and match your box to each phase of the spring transition.
09 The Au Sable has a culture, and it runs deeper than the river itself. Whether you're making your first trip up from the Lower Peninsula or you've been fishing this stretch for years, understanding the unspoken code that locals live by can mean the difference between being welcomed back and being remembered for all the wrong reasons.
10 When July heat pulls the Au Sable down to a trickle, most anglers pack it in. But the fish don't disappear — they just get smarter about where they hold. This is your insider roadmap to the deep pools, shaded bends, and current seams that stack up trophy browns and rainbows all summer long.
11 The shop's name isn't an accident — two flies almost always beat one on the Au Sable. But slapping a dropper on your leader without thinking it through is a fast track to tangles, refusals, and missed fish. Here's how to build and fish tandem rigs the right way for this specific river.
