Hello,
We usually go to St.Clair a week in June, a week in August and the first week of October. June for the eyes. August for the perch. October for smallies and perch. October is the best for the big smallies 2-5 lb. average. I have found that drifting and jigging curly-tail jigs to be the most productive. We always stay on the Canadian side. It is always alot cheaper and the fishing is much better than the Michigan side.
