A warm-water lake type: the DNR groups it with lakes that warm up through summer. This describes the lake type in general, not this lake in particular.

Outline

Drawn from the DNR's 24K hydrography (surveyed 1982), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Water clarity

11 ft Secchi depthClearOlder reading

Last measured Jul 29, 2012. 130 readings on record, 1990 to 2012.

Nothing has been measured in the last 5 years, so this may not match the lake today.

Secchi depth is how far down a white disk stays visible. A bigger number means clearer water. Clear means a Secchi depth of 10 feet or more, moderate 5 to 10 feet, low under 5 feet.

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).
