Spring fishing so far is following suit from last fall up there for me. Very slow. I have only caught 2 fish between all last fall and 4 trips this spring.
I've been there three times this year. Nothing. But I did see a 24ish inch walleye caught and released. I'm guessing in April it will change a bit.
Walleye fishing there replaced muskie fishing as the fish of 10,000 casts.
