I fished Lake St. Clair, Detroit river, and Erie all in the same tournament. You can fish all three in one day if you want. We did best where the Detroit River merged into Erie. The locals told us to find a spot along the trench where a freighter goes by and fish the eddy at the end of the rock dikes. When the freighters come by it stirs up the bottom and the smallmouth bite like crazy for 5 minutes after that. We used mostly spinnerbaits and tubes. Caught a couple of 5’s and the rest 4’s for the tourney…all smallmouth. We ended up getting 3rd in the tourney and won a boat when Alton Jones’s daughter drew our name out of a hat.
