Pierz Lake
Pierz Lake covers 89 acres in Cook County, running to 28 feet, last surveyed by the DNR in 2013. 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.

2005Rates 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.
