Fished Sunday and Monday evening in 22 to 30 FOW both days. Slip bobber and a leech. Caught between 15 and 20 walleyes with six being keepers. Biggest was just under 24", most of the keepers were right around 16". We also kept 4 perch around 9 or 10" long. We stayed at Interlochen State Park where there was a strong hatch of mayflies. Did not really notice them on Long Lake. Wanna kill these ads? We can help!
