Michigan Flies

Rivers / Northwest Lower Peninsula

Betsie River

A 30-60 foot wide river with sand, gravel and clay bottom that is easily affected by rain and run-off. It hosts the earliest kings on the coast, in fishable numbers by the last weeks of August and peaking late September to early October, then coho climbing mid-October, steelhead staging mid-October with a November peak, and lake-run browns October-November. Its Hex runs two to three weeks behind the Au Sable and Manistee.

Hatching in January

Eggs in the drift

In January the drift carries Chinook salmon and coho salmon eggs. Spawning follows water temperature rather than the hatch offset, so these months do not shift. The spawners have left, but eggs are still washing out of the redds. They go pale as they age, so rows marked Washing out list the pale colors.

Signature hatches

Jun 24 – Jul 24
Michigan's biggest hatch and the last of the Au Sable's Big Five: 4-8 duns emerging in the dark from silt banks on muggy nights from about 10 pm, with spinner falls one to three nights after the first duns. Peak on the Au Sable Holy Water is June 20-28 (Mio Trophy Water is the classic Hex water), Manistee June 25-July 5, Pere Marquette June 10-25, Muskegon tailwater June 8-20, and the U.P. two to three weeks later (Superior Flies peak July 5-21). Fish a Hex dun or spinner such as Robert's Yellow Drake, McCoy's All Day Dun or a Boondoggle Hex on a short 6-foot 2X leader, and a Hex wiggle nymph or Spring Wiggler year-round; trout in prime habitat may see up to 2,000 nymphs a day outside the hatch. Watch water temperature from June 10 and expect the hatch within days once the Au Sable holds 62-65 F.
