Thats a great school project. It's good to know they are talking about this stuff in school. If he needs any info have him contact my brother Doug http://home.gwi.net/~fks/ksalmon.html
. He has a great video that was made about the Glen Canyon Dam and the whole dam debate out there and around here. He could probably send him down a copy. I have one that is put out by American Rivers that I could send up also.
