The middle branch (upper river) can be a bit tight at times...depending on how far up you go. If it were me i would concentrate on the flies water between M37 & Gleasons. You can find more info from these sites.

If your not into the salmon thing i would get up there sooner than later. The salmon are in the lower river but a few are starting to push up. I was just there for 3 1/2 days. I stayed in the flies water and never saw another person, thats what i like about early salmon season. I did see about a half dozen salmon in that section...so its not to far off and it will be a zoo.

The fishing was terrific. The rain got the streamer bite going, the river got a slight stain and came up a few inches. We also had nice olives and tricos in the mornings and a fair amount of the dark ISO's...and mousing after dark.
