How to fish South Commerce Lake: deep, two-story water

At 60 feet, this is a two-story fishery: warm-water species work the shallows and weed edges while the deep basin can hold cold-water fish below the summer thermocline. In summer, target the transition where the bottom breaks from the shallow shelf toward the basin; fish suspend along that edge at dawn and dusk. The 13 mapped depth bands make it straightforward to find those breaks before you launch.

Ice fishing on South Commerce Lake

On deep water like South Commerce Lake, the winter bite concentrates along the first major drop-off rather than the deepest basin. Use the contours above to find where the shallow shelf breaks toward deep water and set up on that edge; panfish and walleye slide up and down it through the day. Late ice often pushes fish shallower again. Always verify ice thickness locally before walking out, and remember deep lakes freeze later and less evenly than shallow ones.
