LCO is a deep clear lake with abundant structure: rock, weeds, steep drop-offs, reefs, you name it. Ciscoes provide at least some of the forage base. In years past, LCO used to be a premier trophy fishery, but its size structure has deteriorated somewhat (or so I am told) and the DNR is actively trying to do something about that. This spring, the WI DNR netted 2500 small pike from the lake to try to give the skis and eyes in LCO a better chance (story).
If I were to go chasing an early season ‘lunge in LCO, I’d be working the weeds and bars in musky bay, which is the location of one of the public launches on the north side of the lake. I’ve always liked salt and pepper tubes (to imitate crappies) as an early season offering.
