Lakes / Wisconsin / Deepest Natural Lakes in Wisconsin

Deepest Natural Lakes in Wisconsin

Ranked by maximum depth, from Wisconsin DNR lake data. Only natural lakes are ranked - Lake Wazee, a flooded iron mine at about 350 ft, is deeper than every lake on this list but is man-made, and deep reservoirs are excluded for the same reason.
