There is an abundance of food in that lake, and I'm puzzled as to why they figured the walleye limit should be zero, as I have never had a problem catching them there.
Funny thing is, when they were doing studies, the people doing it were packing up whenever my friends and were heading out, and when we came back in the dark, they were gone.
Middle of the afternoon is a not a good time to do a survey of fish caught in that lake.
