Marion Lake
Marion Lake covers 12 acres in Cass County, running to 60 feet, last surveyed by the DNR in 2022. 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
Present and managed by the DNR. Standard survey gear does not count this species reliably.
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.
