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 1961), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity
4 ft Secchi depthLow
Last measured Jul 19, 2022. 10 readings on record, 1993 to 2022.

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).
