Michigan State Record Lake Sturgeon: 193 lb
The Michigan state record lake sturgeon weighed 193 lb and measured 87 inches. It was caught in 1974 from Mullett Lake in Cheboygan County, and the Michigan DNR still recognizes it as the state mark 52 years later.
Where the record came from
Mullett Lake is one of the Michigan lakes we grade. It holds a Grade B water-quality score today, based on clarity, phosphorus, and chlorophyll-a samples from the EPA Water Quality Portal — a useful check on whether the water that produced a record fish still fishes well.

Michigan ranks 1 of 4 among the states in our index for record lake sturgeon. No state we track has produced a heavier one.
| # | State | Weight | Year | Water |
|---|---|---|---|---|
| 1 | Michigan (this page) | 193 lb | 1974 | Mullett Lake |
| 2 | Wisconsin | 170 lb 10 oz | 1979 | Yellow Lake |
| 3 | Minnesota | 94 lb 4 oz | 1994 | Kettle River |
| 4 | South Dakota | 40 lb | 1990 | Missouri River |
Each figure comes from that state's own fisheries agency. Agencies differ on what they certify — some recognize catch-and-release length records alongside weight — so treat this as a comparison of standing certified weights, not a single national list.
