Water quality quick take
From Wisconsin DNR / Citizen Lake Monitoring readings at Hiawatha Lake - Deep Hole.
Last sampled Aug 2024
Through 2024, somewhat hazy water — summer clarity of 4.4 ft is lower than most monitored Wisconsin lakes.
Based on July–August 2024 averages across 4 volunteer readings.41Mesotrophic5-yr summer TSI
Moderately clear with moderate nutrients — a typical profile for good swimming lakes.

Latest individual samples: Secchi 5 ft (2024-08-29), chlorophyll-a 6 µg/L (2024-08-29), and total phosphorus 183 µg/L (2023-05-22).
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.
