Water clarity

Low, measured Jul 2016

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

4.6 ft Secchi depthLowOlder reading

Last measured Jul 26, 2016. 6 readings on record, 1992 to 2016.

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).
