Historical volunteer-monitoring record for this lake.
Last sampled Sep 1982Volunteer monitoring 1977–1982
DNR volunteers monitored this lake for about 5 years, ending in 1982. In 1982 the water showed elevated algae (chlorophyll ~16 µg/L) and high nutrients (phosphorus ~180 µg/L). After 44 years without samples, these readings describe the lake as it was, not as it is.
The DNR station record reports activity through 2023, but LakeList holds no readings after 1982 — check the station reports for anything newer.

How deep is Lake Wausau?
Lake Wausau is 30 feet deep at its deepest point and averages about 7 feet, according to Wisconsin DNR records.
Is there a free depth map of Lake Wausau?
Yes. LakeList publishes a free interactive depth contour map of Lake Wausau 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 Lake Wausau 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.
