This is a smooth mathematical model, not a survey - real holes, bars, and drop-offs will differ. Community sonar (C-MAP Genesis) overlays where recorded. Not for navigation.LakeList assistant

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2021 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 contextGraham Lake (WBIC 279300) only; target bass/panfish electrofishing metrics are retained and bycatch is not interpreted as population abundance.
Human-reviewed, page-evidenced 2021 fisheries metrics for Graham Lake (WBIC 279300).
- Historical fisheries snapshot; not current fishing regulations or navigation guidance.
- Only metrics explicitly supported by the cited source page were promoted.
- Relative-abundance indices, population estimates, gear limitations and size thresholds retain source scope.

Depth FAQ
How deep is Graham Lake?
Graham Lake is 29 feet deep at its deepest point and averages about 10 feet, according to Wisconsin DNR records.
Is there a free depth map of Graham Lake?
Yes. LakeList publishes a free interactive depth contour map of Graham Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Graham Lake depth map come from?
The interactive depth contours are derived from LakeList depth model. Each contour set passes a visual QA review against the source document before it is published. The depths are a modeled estimate calibrated to the lake's documented maximum depth - not a survey, and not for navigation.
