DNR lake type
Simple, Cool, dark water color
A cool-water lake type: the DNR groups it with lakes that stay cooler through summer. This describes the lake type in general, not this lake in particular.
Outline
Drawn from the DNR's 24K hydrography (surveyed 1991), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity (satellite estimate)
- Summer 20166.5 ft (17 satellite pixels)
No one has measured this lake's clarity in the monitoring data. This is an estimate from satellite images of one summer only, so it may not match the lake today.
Secchi depth is how far down a white disk stays visible. A bigger number means clearer water. The estimate tops out at 16 feet.
Landsat satellite estimates published by the Wisconsin DNR (summers 2016 and 2017), averaged over the lake's outline. Informational use only.

A computer model of this lake's typical weather and water, built from 15 years, 2005 to 2019. Ranges show the middle half of years. The model was not calibrated against measured temperatures for this lake. It is an estimate, not a measurement.
Modeled: U.S. Geological Survey lake temperature data release (doi:10.5066/P9CA6XP8).
