I don't know of anything specific to Tennessee. There are, however, several
drainage maps in a large size that allow you to see relationships between
all of the drainages in North America, and memorize drainages (quite useful
for prepping for comp questions in case your advisor has a bent for
zoogeography...).
The USGS-in-one point offered a 1:3,168,000 scale base map with hydrology,
cities, and state boundaries; our lab has a copy that is ca. 3x5' mounted on
foam-core board. The University of Michigan Museum of Zoology also produced
a hydrology base map [hand-penned!] back in the 1940s. I have a copy that I
have annotated with stream names. I do not know if this is still available.
A call to their publications office might work wonders.
Alternatively, offering to buy a couple beers for the techs-in-the GIS lab
on campus might get you a pretty useful product, especially if they have a
large-format printer handy...
cheers,
Dave
