I can tell you Grand sees equal if not more pressure. Beaver gets quite a bit of pressure but I would call it mostly local pressure except for people traveling in to fish stripers. Funny thing for me personally is that though I have caught far fewer bass on Beaver than I have on Table Rock, I have caught more big bass > 5 lbs. on Beaver, but overall TR fished better than Beaver for black bass for me for numbers, though Beaver has been fishing well the last couple of years.
Swepco, which is a warm water power plant lake, gets hammered during the winter, I won't go near that place on a winter weekend day. But it fishes well, has good average size bass. It is a fertile lake and has Florida strain LM's.
