This is a smooth mathematical model, not a survey - real holes, bars, and drop-offs will differ. Community sonar (C-MAP Genesis) overlays where recorded. Not for navigation.LakeList assistant

Historical volunteer-monitoring record for this lake.
Last sampled Aug 2018Volunteer monitoring 1979–2018
DNR volunteers monitored this lake for about 39 years, ending in 2018. Its final monitored summers showed clear water (~11 ft Secchi) in 2018, low algae (chlorophyll ~3.3 µg/L) in 2018, and low nutrients (phosphorus ~16 µg/L) in 2017. After 8 years without samples, these readings describe the lake as it was, not as it is.

Depth FAQ
How deep is Bass Lake?
Bass Lake is 19 feet deep at its deepest point and averages about 6 feet, according to Wisconsin DNR records.
Is there a free depth map of Bass Lake?
Yes. LakeList publishes a free interactive depth contour map of Bass Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Bass 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.
