Haven’t fished it either but I believe that back in the late 80’s somebody took a huge tiger musky out of there. Some parts of that lake are exceptionally deep jerr
I’ve caught some nice pike there – average size is definitely a lot bigger than what you get out of most metro lakes.
Totally agree about the boat traffic. It’s a super deep, CLEAR lake that can be tough to fish. I would recommend ice fishing it (if you can get access), taking your boat late fall, or if you go in the summer fish at sunrise or sunset.
