From Wisconsin DNR / Citizen Lake Monitoring readings at Schnur Lake - Deep Hole.
Sampled Aug 2025Volunteer monitoring since 2000
Somewhat hazy water — summer clarity of 9.7 ft is lower than most monitored Wisconsin lakes.
Based on July–August volunteer averages from 2022–2024; each value shows its own year.47Mesotrophic5-yr summer TSI

Latest individual samples: Secchi 6 ft (2025-08-26), chlorophyll-a 6 µg/L (2025-08-26), and total phosphorus 14 µg/L (2024-05-19).
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 Schnur Lake?
Schnur Lake is 27 feet deep at its deepest point and averages about 15 feet, according to Wisconsin DNR records.
Is there a free depth map of Schnur Lake?
Yes. LakeList publishes a free interactive depth contour map of Schnur Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Schnur Lake 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.
