Water temperature
Modeled surface-temperature estimate built from seasonal climate, lake depth, and live National Weather Service air temperatures near this lake.

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 Spring Lake - Deep Hole.
Through 2023, murky, algae-prone water — summer clarity of 1.9 ft ranks among the lowest of monitored Wisconsin lakes.
Based on July–August 2023 averages across 4 volunteer readings.Clearer than 1% of 597 monitored Wisconsin lakes with current readings.
High phosphorus points to heavy plant/algae growth pressure.
July/August means; counts in parentheses show how many samples went into each average.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 2023 | 1.9 ft (2) | 69.5 µg/L (2) | — |
| 2022 | 2.1 ft (2) | 68.5 µg/L (2) | — |
Latest individual samples: Secchi 1.5 ft (2023-08-16), chlorophyll-a 50 µg/L (2023-09-06), and total phosphorus 92 µg/L (2022-09-13).
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 2011 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 multi-gear catch, CPUE, length, and size-structure metrics for exact Spring Lake.
