Bill I fish the Saugeen quite a bit. Before you waste the trip make sure you've got fishable water.
Right now it's very much blown.
It's a big river with a lot of volume. Long leads with lots of shot and larger floats in the 11-15 gram range are the norm.
Personally I'd never run a plastic float on the 'geen, only larger balsa floats.
The most readily available are the larger sized Riverwood floats.
Water will be off coloured or at the least a very deep green colour. Fluoro doesn't cut it for me in those high water conditions.
I'd recommend Maxima Ultragreen in 5 or 6lb test. Go big or go home!
Hooks are sized appropriately to the bait you're running. Smaller hooks in the 10-12 range for normal sized roe bags.
Larger hooks in the for bigger bags (which is what you should be running on Friday).
If the water is clear enough live worms under a float are deadly on the Saugeen.
That's live worms, not pink plastic ones .
Don't be afraid to throw larger spinners in sizes 2-3 and 1/4oz spoons.
Cast across and slightly upstream, let sink for a bit then a slow retrieve.
On big water like the 'geen sometimes hardware outproduces all.
Finally, it's a big river don't be intimidated by it. Break the water down into sections and try to interpret where the various seams are. Sometimes they're sitting right in tight, sometimes they're way way out there.
Fish slowly and thoroughly and don't get rooted in one spot. Go for a walk if nothing is happening.
