Hello everyone, I believe the best smallmouth fishery in the united states is lake champlain or lake st.clair for sheer numbers of fish. For trophy fish over 5lbs I would say lake erie at the eastern end (n.y.) and the western end (ont.) in early spring (may) or late fall (oct.-nov.), also the detroit , st.clair river,and the columbia river, or in canada lake simcoe in late june or late fall (oct. - nov.) For truly monster fish 8lbs and over you would have to say the tennesee triangle, pickwick, dale hollow, or wilson/wheeler lakes. In late fall tourneys on lake simcoe and eastern lake erie they have come very close to breaking the 30lb mark for five fish limits. I am just glad I live within driving distance to some of the best smallmouth fishing in the world, lake st.clair, lake erie, and lake simcoe. Good luck to everyone in their quest for monster smallmouth!!!
