From Wisconsin DNR / Citizen Lake Monitoring readings at Fox Lake - Deep Hole.
Sampled Jun 2026Volunteer monitoring since 1987
Murky, algae-prone water — summer clarity of 2 ft ranks among the lowest of monitored Wisconsin lakes.
Based on July–August volunteer averages from 2024–2025; each value shows its own year.68Eutrophic5-yr summer TSI
Nutrient-rich, greener water — more algae and plant growth, common in shallower lakes.

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.

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2019 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 contextFox Lake (WBIC 835800) only; the localized Mill Creek northern-pike estimate remains explicitly separate from the lake-wide estimate.
Human-reviewed 2019 population estimates, gear-specific catch observations, size structure and mortality metrics for Fox Lake.
- Historical survey snapshot; not current regulations or navigation guidance.
- Mill Creek and lake-wide northern-pike estimates are preserved as separate scopes and must not be conflated.
- Appendix 1 values were used for systematic gear-specific catch, CPUE and mean length where rounded narrative values conflict.
- Yellow-perch values are retained only as observed gear-specific samples with the report's sampling-limit caution, not as population estimates.

Depth FAQ
How deep is Fox Lake?
Fox Lake is 19 feet deep at its deepest point and averages about 7 feet, according to Wisconsin DNR records.
Is there a free depth map of Fox Lake?
Yes. LakeList publishes a free interactive depth contour map of Fox Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Fox 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.
