I have had several local fishermen tell me they have caught blues in Chippewa. 40,50,& 60 pounders. I know that they can't be confusing them with Channels, well it's unlikely. Have Blues been intraduces into the lake? It is the largest natural lake in Ohio and at this time it is private. I've caught a few 8-12 pounders there that I thought were blues at first glance, but turned out to be channels. There are probably flatties in there, but I haven't caught any. What's your thoughts?
