Dan,
I am not going any further with this thing, but I will help you get into the discussion.

Please read the post again.
The word MAJORITY is in the sentence within the context of salmon and steelhead returning to the river to spawn.
Since we are all seasoned fisherman, I assumed that we have the knowledge to leave out the springers and the long distance migratory steelhead of the Clear Water, the Grande Ronde, the Snake, etc... as well as those few random fish that hit bait/lures by instinct or chance.

Remember the Barrier Dam pool?
Hundreds of fish yet only a small percentage of them are interested in bait and lures.

Jesus Christ, Dan.

There you go, getting me all mad again.
