Thanks to all of you for the kind words and helpful suggestions. The upper McKenzie area is indeed special, and I feel privileged to live near it.
#1 is very good, but I wonder if the tree trunk is not too intrusive?
#3 seems a bit too dark?
What a fantastic location.
Paulo, I spent quite a bit of time debating myself about the downed tree trunk in the foreground of #1. Does it add to the composition, or as you say, is it too intrusive, drawing too much attention? I have other shots that don't include it, but judged the required changes in perspective to be less appealing. In the end I decided that on balance it was a net positive, after toning it down some. But if others have opinions on this, I would be glad to hear them.
For #3, I intentionally left it pretty dark, because it actually was getting dark out there. But I did lighten it a little, so the key elements would be more visible. Maybe I should have gone a little further.
As a photographer, I prefer the first, but as a flyfisherman I much rather fish in the river shown in photo #3 
. Nice location. I must put it on my 'must visit' list.
I hear you, Bob. As an avid flyfisher myself, I seldom go there without a fly rod. The upper McKenzie river is all native fish, rainbow trout and some cutthroats, catch and release only. There are some real beauties in there, and the frequently swift water makes them feel even bigger than they are. An example from earlier this year:
