Is at the falls reserve?
Lots of bass holding in deep holes. Trout are there but the water might be too warm now.
Worms, small spinners, crayfish etc. There use to be a stocked trout pond but not sure if its still there.
In the town of Goderich you can do some casting of spoons of the pier there are fish there but in low numbers.
It should be flowing nicely with all the rain.
