The main issue is with lake levels.
During the last drought, the lake levels were so low that homes in the coves were land locked.

Look up Lake Keowee.

Thanks,
All the lakes in that area of the country had problems a few
Years ago. Just hope they have recovered somewhat.
Lake Keowee, a good start. Lots of info there.
Just starting to research the area. Looks good, some good looking
Homes there
Thanks again
Merry Christmas all

I second the advice to look at Keowee.
This article explains what I meant about Hartwell.

Keowee is a much prettier lake.
