How we know
- 156lakes where an angler registered one (Master Angler)
- 53lakes where a DNR fisheries survey netted them
A lake can appear in more than one line. A lake that isn’t listed may still have them: records exist only where someone caught, netted or stocked them.
Inland lakes on this list run from 4 to 19,592 acres (median 251) and from 3 to 175 ft deep (median 40 ft).
When and how big bowfin are caught
From 1,456 Master Angler entries, 1981–2025, from all Michigan waters including the Great Lakes. An entry needs a fish at least 27 in, so these describe big fish that anglers chose to register — where and when people fish, not how many fish a lake holds.
Entries by month
The busiest month is June (29% of entries); 4% come in December–February (lighter bars), mostly through the ice.
Size of registered fish
Half were 28.1 in or less, and 9 in 10 were under 30.2 in.

How to recognize it
A long, low dorsal fin running most of the back, a short anal fin, a rounded tail, and a scaleless head. Males carry a dark eyespot ringed in green at the base of the tail.

Life in a Michigan lake
Bowfin are a primitive fish group that has changed little since the age of dinosaurs. They prefer calm, clear, weedy water, and can survive in stagnant, low-oxygen water by gulping air at the surface — even out of water for a while.
Males clear nests in shallow weeds, then guard the eggs and the school of young on their own until the fry reach about 4 inches. Bowfin are ambush predators that come into the shallows at night to feed.
