Tie your line to one eye of the 3 way. Tie a hook on about 1 metre of line to another eye of the 3 way.
Tie the bell sinker with about 30 cm of line to the last eye. Just a worm on the hook so it is stretched out. Bounce the sinker on bottom under the bridge. You gotta have a stMarys river anchor to anchor there or you will likely be leaving it stuck in the rocks.
If you have a little boat that you can lift, you can put it in at that little park right at the bridge, otherwise, if you have to launch, its $5 at Richards landing marina.
If the pearch bite the end of your worm off, you gotta put a new one on. The only way to get the eyes under the bridge is a full worm and no jewelry with it.
So I been told.
At night from shore, a Rapala will work
