Bull trout do not have to have access to salt water so even fish above natural barriers can be Bull Trout. The book I got this from was printed in 2002 so the info is not old. The books id Trout and Salmon of North America by Robert J. Behnke. The author is a Fish Biologist and has put many years into writting this book. The book is actually the best book on salmonoids I have ever read. Each species has more than one realistic illustration, a distribution map and 4-10 pages on each fish (biology, discription, distribution, evolution and classification, and conservation sections). The book covers every salmonoid in North America including many the only exsist in a couple creeks or small drainages. Also included are some extinced salmonoids. I got he book at Borders and it is quite expensive, $40, since it is an hard cover but i believe it was well worth it. If you don't think you want it, just go take a look at it and you might just change your mind.

LOL! Just found out you can get it for only $28 in the internet. $14 for a used one. I gusse I should have shopped around before I bought it at the store!
