Drawn from the DNR's 24K hydrography (surveyed 1983), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Last measured Aug 19, 2008. 44 readings on record, 1991 to 2008.

Nothing has been measured in the last 5 years, so this may not match the lake today.

Measured at the monitoring station named “Lake Windsor - Deep Hole”.

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.
