that's a very pecular lake...I live in that area and have fished that lake on and off for years. once in a "blue moon",a person can go out to the "last week" spots and hammer some really nice ones. But,My luck,if you will...consists of maybe 2...and then as you say,just lookers and nibblers..
It is a very under rated lake as far as fish population..I normally do most of My line soaking there in spring and fall but there are some dandy fish in that lake!
