From Wisconsin DNR / Citizen Lake Monitoring readings at Sheas Lake - Deepest Area.
Last sampled Aug 2023
Through 2023, somewhat hazy water — summer clarity of 5.4 ft is lower than most monitored Wisconsin lakes.

Summer averages (July/August)
July/August means; counts in parentheses show how many samples went into each average.

Latest individual samples: Secchi 4.8 ft (2023-08-30), chlorophyll-a 25 µg/L (2018-09-07), and total phosphorus 51 µg/L (2018-08-10).
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 2025 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 contextLake-specific whole-shoreline nighttime electrofishing after a spring 2025 fish kill; captured and observed-only fish remain separately labeled.
Black crappie dominated the 274-fish captured sample. Bluegill and yellow perch were much less abundant, while only four pumpkinseeds and one northern pike were netted.
- The report was completed March 30, 2026 but covers the May 2025 survey.
- The survey followed a spring 2025 fish kill, which may affect comparison with prior years.
- Two approximately 28-inch northern pike and one approximately 15-inch largemouth bass were observed but not netted; approximate lengths are excluded.
- Bullheads and golden shiners were described only as numerous, so no numeric values are invented.
