Apparently she's never looked at a topo map. Unless they plan to blast away a lot of hills, to join Dale Hollow and Lake Cumberland, they'd have to build the dam in Celina, TN; just down stream from the current Dale Hollow dam.

And it also doesn't make sense that they would build a new dam to generate electricity. Just because your lake is bigger, doesn't mean you'll get more electricity out of it. Once you get a lake to a level, if you want to hold it there, the water coming out can only equal to the water coming in. There's no other major river there that they'd be sourcing water from. Assuming that they're already generating from both Dale Hollow and Cumberland, if they wanted to generate more electricity, they'd build another lake altogether.
