A cool-water lake type: the DNR groups it with lakes that stay cooler through summer. This describes the lake type in general, not this lake in particular.
Outline
Drawn from the DNR's 24K hydrography (surveyed 1962), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
