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 contextThe 2021 comprehensive survey assessed the combined Fish and Mud Lake complex with spring fyke netting and late-spring electrofishing, including a Northern Pike mark-recapture estimate.

Depth FAQ
How deep is Fish Lake?
Fish Lake is 62 feet deep at its deepest point, according to Wisconsin DNR records.
Is there a free depth map of Fish Lake?
Yes. LakeList publishes a free interactive depth contour map of Fish 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 Fish 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.
