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 1992), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity
9.1 ft Secchi depthModerateOlder reading
Last measured Sep 2, 2001. 2 readings on record, 1999 to 2001.

Nothing has been measured in the last 5 years, so this may not match the lake today.
