Actually it was right around now when I used to troll a good bit...August/September. They are doing pretty well on Hartwell trolling right now. The fish tend to spread out suspended this time of year and are prime for trolling if you can get a lure to the depth they are holding. Not sure if Wateree has lots of snags to worry about or not. Hartwell is a flooded forest so you have to be careful to not get too deep with your lures.

In the dead of winter is another good time to troll. 2 years ago when we had several days in the teens, I was out on Murray catching them pretty good jigging but I was marking a ton of fish suspended in the channel that didn't want to eat. Then a couple days later I heard about people catching big numbers on umbrella rigs in the same area. Looking in my fishing log for that weekend the water temps were down to 45 degrees. Not sure what speed to try to troll for the winter. Call Captain Mack, he can tell you exactly how to do it.
