DNR lake type

Water clarity

10.3 ft

Clear, measured Apr 2019

A deep lake type that can hold a cold layer below the warm surface in 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

10.3 ft Secchi depthClearOlder reading

Last measured Apr 22, 2019. 16 readings on record, 1994 to 2019.

Typical summer clarity (June to September): 13.5 ft, clear, from 12 readings (2013 to 2017).

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.
