Lake trout in Michigan
Salvelinus namaycush — native to Michigan, holding water between 46 and 54°F. Michigan's own fisheries records name 5 waters here.
The lake trout is native to Michigan and it is not a river fish. It holds 46 to 54°F and is finished above 59 — colder than anything else on this map, and colder than a Michigan stream runs in summer — so it lives in the Great Lakes and in deep inland lakes, and a river angler meets it, if at all, near a mouth.
The records show exactly that. Four rivers with a page here carry a lake trout stocking record and none carries a survey; seven more waters are named in MDNR's file without a river page to attach them to, which is the shape of the fishery rather than a gap in it. At eighteen to thirty-two inches this is the largest fish on this surface, and it is a char — pale spots on a dark ground and a deeply forked tail, which nothing else here has.

What it is
Salmonidae — char, genus Salvelinus · Salvelinus namaycush
- Grey to bronze-green ground colour covered in pale cream spots — light marks on a dark fish, like a brook trout, and unlike either of the spotted trout.
- A deeply forked tail. Nothing else here has one.
- No pink stripe, no red spots, no halos.
- Lower fins edged white, more faintly than a brook trout's.
Typical length in Michigan is 18 to 32 inches. That is a curated range for water of this kind, not an average of any survey: MDNR's abundance file counts fish per acre and per mile and records no lengths at all, and no other state on this site publishes lengths either.
Native or stocked
Native to the Great Lakes and to a number of deep inland lakes. Michigan's rivers are not lake trout water, and this page says so where the records say so.
Where to find it in Michigan
Waters MDNR's own files put this fish in — a survey station where it was counted, or a planting site where it was stocked — matched to the river pages on this site by position, not by name. Surveyed water is listed first: a survey is a fish somebody counted, a stocking is a fish somebody put there.
| Water | Record | Latest |
|---|---|---|
| Manistee River | 6 stocking records | 2008 |
| Au Sable River | 4 stocking records | 2009 |
| Betsie River | 2 stocking records | 2026 |
| Tawas River | 2 stocking records | 2016 |
| North Channel Muskegon River | 1 stocking record | 1989 |
Other Michigan waters in the same record
Named in MDNR's files without a river page here to link to — mostly lakes and Great Lakes water, which for lake trout is where the fish is. Listed rather than dropped: a page that showed nothing would read as a data failure when it is the actual shape of the fishery.

Where that is on the map
Every subwatershed this site covers in Michigan as a faint dot, and the ones holding the waters listed above lit. A coverage map with this species on it — the map on the front of the site is the map.
When to fish for it
Lake trout hold 46–54°F water and are under real stress above 59°F. On this map's own colours that band is cold water, which is what the river pages and the live map are painting when they run green and blue. The season follows the temperature rather than the calendar: the water is in the band early and late in the day through the summer, and all day either side of it.
Spawning: October and November, over cobble and rubble reefs — in the lakes, not in the rivers.
How to catch it
Deep, cold lake water. This is a Great Lakes and inland-lake fish that a river angler meets, if at all, near a river mouth or in the coldest big-lake water rather than up a stream.

Rules for lake trout in Michigan
Michigan sets a minimum size per species under each of its four stream regulation types, and these are that column for lake trout. The creel is a trout total across species, not a limit on this one. Snapshot taken 2026-08-16 — the book on the water is the book.
| Type | Minimum size | Season | Creel |
|---|---|---|---|
| Type 1 1960 waters | 10" | Last Saturday in April–September 30th | 5 fish, with no more than 3 trout 15“ or greater. Zero (0) Arctic Grayling. |
| Type 2 14 waters | 10" | Last Saturday in April–September 30th | 5 fish, with no more than 3 trout 15“ or greater. Zero (0) Arctic Grayling. |
| Type 3 59 waters | 10" | January 1st–December 31st | 5 fish, with no more than 3 trout 15“ or greater. Zero (0) Arctic Grayling. |
| Type 4 133 waters | 10" | January 1st–December 31st | 5 fish, with no more than 3 trout 15“ or greater. Zero (0) Arctic Grayling. |

Habitat notes
Deep, cold lake water. This is a Great Lakes and inland-lake fish that a river angler meets, if at all, near a river mouth or in the coldest big-lake water rather than up a stream.
- 46–54°F preferred
- 59°F upper limit
- cold on this map's colours
The four thermal classes named there are the ones every river on this site is painted with, at breaks of 58, 64 and 70°F. A river page showing cold water is showing water inside this fish's band; that is the whole point of the colour.

Lake trout in the other states
The same fish, on different water and under different rules. Michigan's sand-bottomed rivers, Wisconsin's driftless springs, Minnesota's North Shore, Virginia's mountain brook water and North Carolina's tailwaters and freestone gradient are five fisheries, and the limits differ with them.
