I lived in Frisby for 2 years and walked round the main lake almost every night looking for the bigger fish that were said to be in there. Never saw anything bigger than a mid 20 common (the one with the little orange birth mark that's still in there I believe). There was a stocking a few years ago but they seemed to go nowhere for some reason, not good growers. The lake itself looks perfect for carp, it has everything, but for some reason it's never produced anything of note.
Get your net dried out properly @B.C. as they had confirmed KHV either last year or the year before mate.
