I agree. I don't imagine there were even that many.

This whole teasing out by brood line started for me in the 70s, looking at steelhead punchcard data. All the graphs, plotted annually for the streams with primarily wild fish in the catch, showed a lot of variation. If, though, you broke it up into 4 separate lines (assuming as we did, then, that 2.2 fish were the vast majority of a wild run) in almost every stream for all 4 lines the lines all went down. Wild steelies were in trouble 40 years ago, before it was cool, or job enhancing, to notice.
