From Wisconsin DNR / Citizen Lake Monitoring readings at Presque Isle - Site 2 - Center SW Deep.
Sampled Aug 2025Volunteer monitoring since 1989
Very clear, low-algae water — summer clarity of 18.8 ft puts it among the clearest tenth of monitored Wisconsin lakes.
Based on July–August 2025 averages across 4 volunteer readings.35Oligotrophic5-yr summer TSI
Very clear, low-nutrient water — often deep, with limited plant growth.

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.
