Fishing forecast
Weather-based planning built from the National Weather Service hourly forecast near this lake.
Checking wind, precipitation, and near-term weather windows.
Water temperature
Modeled surface-temperature estimate built from seasonal climate, lake depth, and live National Weather Service air temperatures near this lake.
Seasonal estimate. Checking current National Weather Service air temperatures…
Warmest water of the year. Fish hold deeper or feed in low light; swimming and watersports are at their best.
Estimates are modeled, not measured. Actual temperatures vary with depth, wind mixing, and recent weather — verify conditions before swimming, boating, or heading onto ice.
DNR water check
From Wisconsin DNR / Citizen Lake Monitoring readings at White Potato Lake - Deep Hole.
Somewhat hazy but low-algae water — summer clarity of 6 ft is lower than most monitored Wisconsin lakes.
Based on July–August volunteer averages from 2022–2025; each value shows its own year.Moderately clear with moderate nutrients — a typical profile for good swimming lakes.
Clearer than 23% of 596 monitored Wisconsin lakes with current readings.
Moderate phosphorus can support noticeable plant/algae growth.
July/August means; counts in parentheses show how many samples went into each average.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 2025 | — | 5.0 µg/L (2) | 20.5 µg/L (2) |
| 2024 | — | 2.0 µg/L (1) | 19.0 µg/L (1) |

Latest individual samples: Secchi 5 ft (2022-08-23), chlorophyll-a 3 µg/L (2026-06-15), and total phosphorus 13 µg/L (2026-06-15).
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
Structured LakeList extraction from the 2020 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.
Human-reviewed, page-evidenced angler effort, projected catch and projected harvest metrics for White Potato Lake's 2019-2020 creel season.

Depth FAQ
White Potato Lake is 11 feet deep at its deepest point and averages about 5 feet, according to Wisconsin DNR records.
Yes. LakeList publishes a free interactive depth contour map of White Potato Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
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.
