I believe Tennessee is the Eastern American redoubt, it has enough lightly populated areas and the climate to survive when SHTF.
That being said if water is the obstacle that you will use to defend your domain, I can't think of anything better (You didn't say but it could be assumed you are on an island)
My only input is don't think the "fresh water lake" is a reliable source of drinking water. I know you didn't even mention that and I assume you have a well, or a really good filtration system, but anyone that lives next to an open source of water and thinks they have it figured out is fooling themselves.
To elaborate not only are you subject to the dead bodies piled into the source upstream, but you are also subject to radiation, or ash from a major volcano eruption, or biological warfare.
My suggestion is to have a well.
