Could be lakers, whitefish or cisco. Try to upsize or downsize your bait, switch up your jigging technique, dead stick, etc. All sorts of things you can do.
A decent amount of 'Ok' pike (say 5-8lbs) but you'd be hard pressed to get anything bigger with consistency.. Some giant muskies, but those are few and far between. I fish it all the time (Probably 2-3 times a week once late May hits).. Fun lake, the boat traffic can be awful however and she whips up quick with the right wind.
You wanna talk about fog! Ran the electronics all the way out, couldn't see a thing.. Wasn't worried too much about other boat traffic in this place. Was a bit unnerving but the fish co-operated.
