Lake Hartwell Fishing and Marine on Hwy 24 would be a great place to get started, they are friendly and knowledgeable there. You could probably spend a whole month just in the Tugaloo arm and fish something different every day. Not sure about the walleye, but they do stock them in the lakes above the Tugaloo so there's a chance there are some in there. Fishing for stripes seems to be a live bait around the bridges kinda thing. Boat docks and points with rock and or brush with some contour are a good place to look for Largemouths and spots. It's hard to beat a shakeyhead for that kind of fishing, when they are aggressive a jerkbait or crankbait is a good way to go. Since your gonna be in the area for a little bit I'd recommend a trip up Hwy 11 to check out Lake Jocassee. Hartwell is a fun lake but not always consistent day to day, however it's so big and varied that there is usually something going on somewhere. Hope this gets you headed in the right direction.
