Elysian can have a good bite in October. Problem is, it’s suffered a couple winterkills recently. Didn’t fish it last fall, but the fall before had pretty good luck there.
That said, fish the points and rock piles. Cast cranks at them, or cork them.
Francis is kind of a tougher one for eyes. It has its days and I have done well out there in the past. It’s hit or miss though. Here you’re looking at a couple nice points, wind on em, cast cranks to em. Also jigging/live bait rigging the east and north part of the main lake can be good.
As has been mentioned, Tetonka is generally a pretty good fall bite. Water temp near 48-52 its prime. Use your graph, lots of classic walleye structure that holds them. If the water temp is up higher, cast cranks to rocks or remaining weeds.
