Has anyone even seen a live walleye out of cedar lake?
No, you have to keep them in the water to live.
I have only fished Cedar about 5 times in my life, so I am not a good survey source. I need to fish it more, especially since it is so close to me. I have never caught or seen a walleye there in my 5 trips. I believe PaulD and PDona know Cedar well, and one or both have caught/seen walleye there.
