The next time you go out on Lake St. Clair try hitting some of the canals, or the weedy areas between Metro beach, and Huron point, by the mouth of the clinton river. There's also some great carp shooting if you go up the spillway a little ways and watch along the banks for carp activity. Since the water in the lake is still somewhat low, the canals provide some excellent shooting. Just stay away from peoples boats and you'll be fine.
Good luck the next time out.
