On the Clackamas at about Barton yesterday some guys passed in a boat who claimed they were seeing some up there, which I rate as less than scientific data but is backed up by the dam counts
They are in there for sure, all the way up to the dam (over 800 wild coho this month). I seent 'some for sure. There's gotta be some up to eagle creek.
Edit: Whoops, I'm talking about the Clackamas here, not the Sandy.
