I’ve always had better luck near rockaway for bass due to the bigger “channel swings” and seems like more consistent water temps, but those creeks by powersite I have caught some smaller bass out of. As far as navigating, I’ve personally never had much trouble, just follow the channel. Plenty of dirt shallow docks on that end of the lake though as it’s not a supper deep lake. They’ve been pulling a lot of water through the lake recently and the shad have been flowing through the turbines on the Table Rock side. When the water flows, lake rises, similar to a TVA lake. Jerkbait over the grass lines, an a-rig, and jig on the steep banks. Probably wouldn’t hurt to toss a trout colored glide bait around either(one that’s dark trout colors, as they get a dark red in them this time of year). Catch one, slow down and pick apart the area, there’s likely to be more. It can be tricky, but there are some good ones in that lake. Good Luck!
