Water quality quick take
Historical volunteer-monitoring record for this lake.
Last sampled Jun 2025Volunteer monitoring 2000–2025
DNR volunteers monitored this lake for about 25 years, ending in 2025. Its final monitored summers showed hazy water (~5.2 ft Secchi) in 2025, high algae (chlorophyll ~39 µg/L) in 2001, and high nutrients (phosphorus ~62 µg/L) in 2000. After 1 year without samples, these readings describe the lake as it was, not as it is.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 2017 | 8.0 ft (1) | — | — |
| 2000 | — | — | 62.0 µg/L (1) |

Depth FAQ
How deep is Sweeny Lake?
Sweeny Lake is 18 feet deep at its deepest point, according to Wisconsin DNR records.
Is there a free depth map of Sweeny Lake?
Yes. LakeList publishes a free interactive depth contour map of Sweeny Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Sweeny 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.
