The river going through Nashville is the Cumberland. The lakes are Old
Hickory and Percy Priest. Old Hickory is part of the Cumberland River
impoundments but and is accessible by a lock on the river. Percy Priest is
not. The lakes in this area are governed by the Army Corps of Engineers,
and their rules discourage liveaboard.
There is a marina called Rock Harbor on the Cumberland about 13 miles
downstream from Nashville that seems to allow liveaboard, however.
I live in the area, so if you'd like more info, please ask. Pls e-mail by
dropping the "nospam".
