Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2006 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 contextexact named lake
Human-reviewed population, catch, recapture, length, density and size-structure metrics for exact Manson Lake.
- Historical survey snapshot; not current regulations or navigation guidance.
- Stocking histories, regulations, recommendations, comparison-water values, creel values and unsupported chart-only values were excluded.
- The public Pine Lake source is marked draft, so its draft status is retained in limitations even though its exact Forest County name and WBIC are verified.

Depth FAQ
How deep is Manson Lake?
Manson Lake is 54 feet deep at its deepest point, according to Wisconsin DNR records.
Is there a free depth map of Manson Lake?
Yes. LakeList publishes a free interactive depth contour map of Manson 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 Manson 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.
