Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2018 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 contextShell Lake (WBIC 2496300) only
Human-reviewed 2018 gamefish, panfish and juvenile-walleye metrics for Shell Lake.
- Historical survey snapshot; not current regulations or navigation guidance.
- Only explicit report observations, estimates and creel metrics were promoted; management targets, lake-class comparisons and unsupported chart-only values were excluded.
- Metric source pages, survey years, methods, units and exact waterbody scope are retained.

Depth FAQ
How deep is Shell Lake?
Shell Lake is 36 feet deep at its deepest point and averages about 23 feet, according to Wisconsin DNR records.
Is there a free depth map of Shell Lake?
Yes. LakeList publishes a free interactive depth contour map of Shell 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 Shell 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.
