Fern Lake
Fern Lake covers 72 acres in Cook County, running to 65 feet, last surveyed by the DNR in 2024. The Minnesota DNR has not published bathymetry for this lake, so there is no depth map here, just the survey record: what the nets held and how big it ran.
DNR survey data
Fish species
No recent survey rating.
Last recorded in the 1992 survey and not seen since.
Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear — which is why the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, the page shows presence and size only. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey. You can read every number on this page without an app or an account.
