Just a quickie for you. There's a dynamite trolling bite happening right now on Lake Koshkonong. I hit it today, and didn't even make it out onto the lake until the fog lifted at 9:30 but still caught plenty of fish.
Fished two areas, got more than a dozen walleyes, the biggest was better than 6lbs. Dozens of whitebass and even a few bonus catfish.
Longline trolling #11 and #13 floating rapalas was the key. Orange, Chartruese and silver and firetiger all produced trolling in 4-6 feet of water of the ends of mainlake points between 2.2-3.2 mph.
I also tried some bottom bouncer/spinner harnesses but I kept getting bit of by northerns so I went straight to the crankbaits.
