Historical volunteer-monitoring record for this lake.
Last sampled Aug 2020Volunteer monitoring 1973–2020
DNR volunteers monitored this lake for about 47 years, ending in 2020. Its final monitored summers showed crystal clear water (~19.3 ft Secchi) in 2019, very low algae (chlorophyll ~2.5 µg/L) in 2020, and very low nutrients (phosphorus ~10 µg/L) in 1974. After 6 years without samples, these readings describe the lake as it was, not as it is.

Depth FAQ
How deep is Flambeau Lake?
Flambeau Lake is 78 feet deep at its deepest point and averages about 28 feet, according to Wisconsin DNR records.
Is there a free depth map of Flambeau Lake?
Yes. LakeList publishes a free interactive depth contour map of Flambeau Lake at a typical 10-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Flambeau 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.
