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 1972), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity
9.2 ft Secchi depthModerateOlder reading
Last measured Sep 8, 2000. 2 readings on record, 1999 to 2000.

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.
