people eat walleye from lake o, people eat pike and bass from lake o, i see people taking steelies all the time from lake o, they are edible, a lot of the toxin poisoning is bullcrap, IMHO, g-bay fish also has toxins, its the smoke factories and crap on the west side of lake o, the further east you are on lake o, the more edible the fish are.
no.........the reason why lake is so polluted is because it the final lake in the chain, everything from superior, huron, st clair and erie flow into it, lot of bad stuff coming from my old stomping grounds on the st clair river
