Historical volunteer-monitoring record for this lake.
Last sampled Mar 2025Volunteer monitoring 1976–2025
DNR volunteers monitored this lake for about 49 years, ending in 2025. Its final monitored summers showed hazy water (~4 ft Secchi) in 2012, very low algae (chlorophyll ~1.5 µg/L) in 1994, and low nutrients (phosphorus ~15.3 µg/L) in 2012. After 1 year without samples, these readings describe the lake as it was, not as it is.

Wisconsin DNR fisheries survey
Fish population survey
Structured LakeList extraction from the 2021 DNR fisheries survey. Population estimates, density, and catch-rate indices use different units, methods, and scopes, so each value is presented in its original form rather than normalized against a different measure.

Depth FAQ
How deep is Irogami Lake?
Irogami Lake is 5 feet deep at its deepest point and averages about 2 feet, according to Wisconsin DNR records.
Is there a free depth map of Irogami Lake?
Yes. LakeList publishes a free interactive depth contour map of Irogami Lake at a typical 5-foot interval, with an optional 3D underwater view, derived from LakeList depth model survey data.
Where does the Irogami 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.
