I just read the Obed Lake thread and didn't want to hijack. Forgive my ignorance, but could someone please explain this to me? I not an overly avid fisherman, I enjoy it and and am getting back into it, but I haven't paid alot of attention to "fishing issues" in recent years. What is the deal with people putting perch into trout lakes? Why do they do it? How does it ruin the lake? Just curious. Thanks.
