there are some nice perch in swan when I go home to see my folks in oneill around the holidays I usually hit it up 2 winters ago we caught caught a lot of 8 and 9 inch perch last winter we caught fish up to 11 inches but had to turn the lake into swiss cheese to catch them my advice is larger minnows or a bigger lindy rattln flyr spoon tipped with minnow head this way you don't have to fight off so many small fish the small fish just clean u off before the bigger fish get there if ur using wax worms also if you light up the ice at swans deepest point at nite you can catch some really big crappies 16+ inch fish
