Made it out fishing on BSL on sunday. My buddy ended up starting the day with a 21" eye about two seconds after dropping his line. He broke off on two more. We caught a good supply of Jumbo perch with a tuli and many pike mixed in. Ice was 14-15 inches but off the road it was sloppy! I did see people driving but I am still not sure of it yet.
Without giving away a friend's secret . . . one of the people I fish with when I come up there has a spot on BSL where he catches walleye through the ice on tipups. He never catches a lot, and some days they do not show, but when the do they are usually decent sized. Last year he also pulled a 43" northern through the ice on BSL. So they are there, like anything else you just have to work for them.
