Have a look at the river posters for 14 Georgia rivers on the Brown's Guides website.

The huge amount of information on these posters can be viewed in detail using Adobe Acrobat, printed in small format on a desktop printer, or sent to a local print shop and reproduced in full 24-inch X 36-inch format. 

The posters tell the story of each watershed through illustrations, graphics and text. Great for grammer schools, middle schools, high schools, and any environmental group.
