It would make sense that the pike in little bow were running out of food. We used to catch them all the time with full bellys of baby lyng, I remember one was spat up on the ice still wriggling around, then they started to have nothing or the odd perch inside. It is weird that the lake suddenly got kinda crappy. I did however land a 5 pound walley there last year on a jig and minnow right in the canal through the ice. Whats his email?
