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 2024 walleye/muskellunge assessment with incidental pike, bass and panfish results; adult definitions and size thresholds remain explicit.
DNR estimated 1,531 adult walleyes, documented stocked muskellunge, abundant adult pike, high proportions of larger bass and abundant yellow perch.
- Bass were not primary targets; adult bass metrics remain incidental-sample scoped.
- The one-page result sheet does not print survey effort beyond targeted muskellunge CPUE, so no effort is inferred.
- Other-species presence and regulations are not converted into survey metrics.

Depth FAQ
How deep is Plum Lake?
Plum Lake is 57 feet deep at its deepest point and averages about 20 feet, according to Wisconsin DNR records.
Is there a free depth map of Plum Lake?
Yes. LakeList publishes a free interactive depth contour map of Plum Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Plum Lake depth map come from?
The interactive depth contours are derived from C-MAP Genesis community sonar (derived). Each contour set passes a visual QA review against the source document before it is published. The depths are derived from community sonar recordings (C-MAP Genesis Social Map, used with permission), with gaps between recordings interpolated; not for navigation.
