A river-like water type, with flow instead of a still basin. This describes the lake type in general, not this lake in particular.
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 1969), 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 11, 2018. 11 readings on record, 2014 to 2018.
Typical summer clarity (June to September): 5 ft, moderate, from 11 readings (2014 to 2018).
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.

A computer model of this lake's typical weather and water, built from 15 years, 2005 to 2019. Ranges show the middle half of years. The model was not calibrated against measured temperatures for this lake. It is an estimate, not a measurement.
Modeled: U.S. Geological Survey lake temperature data release (doi:10.5066/P9CA6XP8).
