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

4.1 ft Secchi depthLowOlder reading

Last measured Aug 7, 2001. 1 reading on record, 2001.

Only one reading is on record.

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.
