DNR water check
Historical volunteer-monitoring record for this lake.
DNR volunteers monitored this lake for about 11 years, ending in 1990. Its final monitored summers showed clear water (~12.3 ft Secchi) in 1990, low algae (chlorophyll ~4 µg/L) in 1979, and very low nutrients (phosphorus ~10 µg/L) in 1979. After 36 years without samples, these readings describe the lake as it was, not as it is.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 1979 | — | 4.0 µg/L (1) | 10.0 µg/L (1) |

Depth FAQ
Ada Lake is 60 feet deep at its deepest point and averages about 16 feet, according to Wisconsin DNR records.
Yes. LakeList publishes a free interactive depth contour map of Ada Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
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.
