Outline
Numbered dots are boat landings; tap one for directions. The list below has the same numbers. 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
6.6 ft Secchi depthModerateOlder reading
Last measured Sep 10, 2003. 24 readings on record, 1993 to 2003.
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.
