PaPond,

Some of the books I own on the subject include:

Hunter, Christopher J. Better Trout Habitat: a Guide to Stream Restoration and Management.
Washington D.C.: Island Press, 1991.

Cushing, Colbert E. and J. David Allen. Streams: Their Ecology and Life.
Hong Kong: Academic Press, 2001.

Seymour, Richard. Fishery Management and Keepery.
London: Charles Knight & Co. Ltd, 1970.

Platts, Carter. Trout Streams.
London: The Harmsworth Press Ltd, 1977(?).

Needham, Paul R. Trout Streams: Conditions that Determine their Productivity snd Suggestions for Stream and Lake Management.
Ithaca, New York: Comstock Publishing Company, Inc. 1938.

Mullan, James W. Trout Stream Management in Massachusetts
Massachusetts Division of Fisheries and Game.

Better Trout Habitat is probably my favorite of the above, although I have found all of them to be helpful. If you cannot find these locally you should be able to find them and other similar books on Abebooks.com, Amazon or any of the other on-line book sellers. I am looking forward to Mr. Mitchell's upcoming articles. Good luck with your project.
