Numbered dots are boat landings; tap one for directions. The list below has the same numbers. Drawn from the DNR's 24K hydrography (surveyed 1978), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Water clarity

3 ft Secchi depthLow

Last measured Sep 25, 2025. 267 readings on record, 1987 to 2025.

Typical summer clarity (June to September): 2.1 ft, low, from 16 readings (2021 to 2025).

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.

Measured: Wisconsin DNR via the Water Quality Portal (checked Oct 23, 2026). Modeled: U.S. Geological Survey lake temperature data release (doi:10.5066/P9CA6XP8).
