This is a smooth mathematical model, not a survey - real holes, bars, and drop-offs will differ. Community sonar (C-MAP Genesis) overlays where recorded. Not for navigation.LakeList assistant

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 2022 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 contextHatch Lake (WBIC 282800) only; metrics retain species, gear and 2022 sample scope.
Human-reviewed 2022 relative-abundance and size-structure metrics for Hatch Lake.
- Historical survey snapshot; not current regulations or navigation guidance.
- No walleye population estimate was made because sample size was low.
- Only current-year page-evidenced values were promoted; historical trend-chart values were excluded.

Depth FAQ
How deep is Hatch Lake?
Hatch Lake is 12 feet deep at its deepest point and averages about 4 feet, according to Wisconsin DNR records.
Is there a free depth map of Hatch Lake?
Yes. LakeList publishes a free interactive depth contour map of Hatch Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Hatch 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.
