Drawn from the DNR's 24K hydrography (surveyed 1974), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity
1.7 ft Secchi depthLowOlder reading
Last measured Aug 7, 2001. 1 reading on record, 2001.

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).
