Outline
Drawn from the DNR's 24K hydrography (surveyed 1991), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity
18 ft Secchi depthClear
Last measured Aug 24, 2026. 102 readings on record, 2002 to 2026.

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).
