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 contextRandom Lake (WBIC 30300) only
Human-reviewed 2017-2018 predator, bass and panfish metrics for Random Lake.
- Historical survey snapshot; not current regulations or navigation guidance.
- Only explicit report observations and estimates were promoted; management targets, comparison-lake values and unsupported chart-only values were excluded.
- Metric source pages, survey years, methods, units and exact waterbody scope are retained.

Secchi clarity is how deep a black-and-white disk stays visible from the surface — more feet means clearer water.
Chlorophyll-a is an algae pigment; higher values signal more algae in the water column.
Total phosphorus is a nutrient that feeds algae and aquatic plants. It is not a weed survey — depth, bottom type, water movement, and management change the actual lake experience.

Depth FAQ
How deep is Random Lake?
Random Lake is 22 feet deep at its deepest point and averages about 6 feet, according to Wisconsin DNR records.
Is there a free depth map of Random Lake?
Yes. LakeList publishes a free interactive depth contour map of Random 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 Random 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.
