Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2024 DNR fisheries survey. Population estimates, density, and catch-rate indices use different units, methods, and scopes, so each value is presented in its original form rather than normalized against a different measure.
Survey indicatorsValues keep their source unit and method; unlike measures are not scaled or compared.
Management contextLake-specific October 28, 2024 whole-shoreline fall electrofishing sample; every CPUE and size metric retains electrofishing gear scope.
DNR documented above-average largemouth-bass abundance, excellent bluegill size structure, naturally reproducing northern pike and a limited yellow-perch sample.
- Fyke netting is preferred for northern pike and yellow perch; their electrofishing CPUE remains gear-specific.
- The narrative and species table report a northern-pike count of six while the all-species community table reports seven; the repeated count of six is retained and the conflicting table value excluded.
- The page-7 photo caption says 34.9 inches while narrative/table say 34.8; the repeated 34.8 value is retained and the caption value excluded.
- Figure captions incorrectly say 2014; title, methods, results and tables establish the survey year as 2024.
