Triangle Lake
Triangle Lake covers 300 acres in Lake County, running to 43 feet, last surveyed by the DNR in 2020. 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.

2003Rates 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.

What fish are in Triangle Lake?
The most recent DNR survey (2020) recorded walleye, largemouth bass, smallmouth bass, northern pike, bluegill, yellow perch, rock bass.
Is Triangle Lake stocked?
Yes. The DNR stocked walleye in 2024; the stocking table on this page lists every year back to 2018.
