Water quality quick take
Historical volunteer-monitoring record for this lake.
Last sampled Aug 1999Volunteer monitoring 1976–1999
DNR volunteers monitored this lake for about 23 years, ending in 1999. Its final monitored summers showed slight haze water (~7.5 ft Secchi) in 1990, elevated algae (chlorophyll ~13 µg/L) in 1991, and low nutrients (phosphorus ~18 µg/L) in 1991. After 27 years without samples, these readings describe the lake as it was, not as it is.

| 1999 | 6.6 ft (1) | 20.0 µg/L (1) | 22.0 µg/L (1) |

Depth FAQ
How deep is Crooked Lake?
Crooked Lake is 32 feet deep at its deepest point and averages about 12 feet, according to Wisconsin DNR records.
Is there a free depth map of Crooked Lake?
Yes. LakeList publishes a free interactive depth contour map of Crooked Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from C-MAP Genesis community sonar (derived) survey data.
Where does the Crooked Lake depth map come from?
The interactive depth contours are derived from C-MAP Genesis community sonar (derived). Each contour set passes a visual QA review against the source document before it is published. The depths are derived from community sonar recordings (C-MAP Genesis Social Map, used with permission), with gaps between recordings interpolated; not for navigation.
