A cool-water lake type: the DNR groups it with lakes that stay cooler through summer. This describes the lake type in general, not this lake in particular.
Outline
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
5.5 ft Secchi depthModerateOlder reading
Last measured Sep 14, 2020. 15 readings on record, 2019 to 2020.
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.
