Latest individual samples: Secchi 16 ft (2026-05-28), chlorophyll-a 1 µg/L (2026-06-23), and total phosphorus 12 µg/L (2026-06-23).
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 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 contextPorters Lake (WBIC 246900) only. Bass and panfish metrics retain the 1.3-mile spring electrofishing sample scope; Northern Pike is labeled bycatch and is not interpreted as population abundance.
Human-reviewed, page-evidenced 2021 spring electrofishing metrics for Porters Lake (WBIC 246900).
- Historical fisheries snapshot; not current fishing regulations or navigation guidance.
- Only values explicitly supported by the cited source page were promoted; 2017 comparison values were excluded.
- Northern Pike was electrofishing bycatch; no Northern Pike abundance index or population estimate is reported.
- Low-sample Black Crappie, Rock Bass and Yellow Perch size indices retain their sample context and are not population estimates.

Depth FAQ
How deep is Porters Lake?
Porters Lake is 16 feet deep at its deepest point and averages about 7 feet, according to Wisconsin DNR records.
Is there a free depth map of Porters Lake?
Yes. LakeList publishes a free interactive depth contour map of Porters Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Porters 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.
