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

Water quality quick take
Historical volunteer-monitoring record for this lake.
Last sampled Oct 2007Volunteer monitoring 1994–2007
DNR volunteers monitored this lake for about 13 years, ending in 2007. In 2007 the water showed clear water (~10.4 ft Secchi), low algae (chlorophyll ~3 µg/L), and low nutrients (phosphorus ~14 µg/L). After 19 years without samples, these readings describe the lake as it was, not as it is.

Depth FAQ
How deep is Beaver Lake?
Beaver Lake is 16 feet deep at its deepest point and averages about 8 feet, according to Wisconsin DNR records.
Is there a free depth map of Beaver Lake?
Yes. LakeList publishes a free interactive depth contour map of Beaver Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Beaver 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.
