From Wisconsin DNR / Citizen Lake Monitoring readings at Lake Minnesuing - Deep Hole.
Last sampled Jul 2025Volunteer monitoring since 1991
Through 2025, somewhat hazy water — summer clarity of 6 ft ranks among the lowest of monitored Wisconsin lakes.
Based on July–August volunteer averages from 2023–2024; each value shows its own year.46Mesotrophic5-yr summer TSI
Moderately clear with moderate nutrients — a typical profile for good swimming lakes.

Latest individual samples: Secchi 4.3 ft (2024-06-30), chlorophyll-a 6 µg/L (2025-07-27), and total phosphorus 28 µg/L (2019-05-31).
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.

Depth FAQ
How deep is Lake Minnesuing?
Lake Minnesuing is 43 feet deep at its deepest point and averages about 18 feet, according to Wisconsin DNR records.
Is there a free depth map of Lake Minnesuing?
Yes. LakeList publishes a free interactive depth contour map of Lake Minnesuing at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Lake Minnesuing depth map come from?
The interactive depth contours are derived from LakeList depth model. Each contour set passes a visual QA review against the source document before it is published. The depths are a modeled estimate calibrated to the lake's documented maximum depth - not a survey, and not for navigation.
