The other factor you have to remember is that most of the tailwaters before they became tailwaters were warm water fisheries and did not support most of the common insects that we see today in a cold water enviroment. As Hugh has pointed out the changing stream bottoms play a big roll in what insects survive. The huge amount of didymo in the S Holston I think has already changed the hatches, but that is only my opinion.
