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…
Comfortable summer pattern. Bass and panfish are active; early and late hours beat the midday heat.
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 Horseshoe Lake - Deep Hole.
Through 2024, elevated nutrients in the most recent monitored summers.
Based on the newest individual DNR samples — too few to average.Elevated phosphorus supports strong plant/algae growth pressure.
No recent clarity readings — last measured 2018. No recent algae readings — last measured 2018.
July/August means; counts in parentheses show how many samples went into each average.

Latest individual samples: Secchi 8 ft (2024-08-19), chlorophyll-a 14 µg/L (2021-08-10), and total phosphorus 38 µg/L (2024-07-17).
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.
