Most lakes consist of many types of structure. For panfish, I typically look at a few different things. Holes and humps are always good places to look for fish. Other features I look for are tight break lines near deep water (Fast drop offs, also called transition areas), and weed lines. Early ice, Panfish will often cruise shallow in weeds, so dont overlook anything! stay open minded, and remember that mobility is key to finding fish on the ice!
