He, he, he. Don't you just love what the Catawba River Authority and Duke Energy have done to the lakes?
Humps and off-shore structure are big. Docks that are in deeper water. For instance, I had some docks that I used on Wateree, that were in 12-15 feet of water, as opposed to some close by that were in 5.
For some of the lakes down there, there are some pretty good maps available. Others not.
Look for major breaks/drops, and of course creek channels. However, down there, most of the creek channels have long ago 'silted' over. The other thing you are going to find, is 'most' of the successfull fisherman on your new lakes, plant and fish brushpiles. Lot's of them. You need to have real good electronics, and look for brushpiles planted throughout the lakes.
