Don't know if this will help, or not ... info is dated:
but, we used to catch quite a few nice SM & Ky's in mid to late Oct - fishing the shale islands on the main lake, just above Beaver Creek. Most were caught using big minnows on a jighead, or splitshotting a big minnow ... casting towards the bank and letting it "swim/fall" back towards the boat. (mostly during the early AM hours & with only a slight chop on the water) -- bigger chop ... we used Crazy Shad topwater prop plugs (clear w/blu face). Later on in the morning, we'd make our way into Beaver Creek ... looking for surface feeding activity. Caught nice fish using those same Crazy Shads, & Silver Buddys (white) ... fan casting points & pockets. That was fairly productive, if Shad schools were present. Otherwise, we would continue using the minnow rigs ... targeting the pockets, points, cliff walls, and islands. Never went very far into Beaver Creek ... just fished the secondary points to the left of the little island in the mouth of the creek.

We always put in at Jamestown, and to reach the shale humps/islands above Beaver Creek, we would go thru the "cut thru" to the main lake and cut across towards the cliff walls ... shale islands are just off to the right. Beaver Creek is just a little ways down from there (going towards dam area) on the left. (from the Grider Hill area, it would be on your right - same side of lake, heading away from dam). You should probably be able to use these same baits/techniques in the Grider Hill area ... if you can't or don't want to run the lake.

Depending on water levels, temps, & clarity .... most fish were caught on or near surface/bank, or around the 15-20ft depths (esp on points). Don't know what to tell you about Walleye ... only caught them by accident, at C-land -- and that was crankin around submerged brush, in Spring. ....... luck2ya ... cp
