hey man most of the water on the upper river is a lot of pocket water, try to find slower tail out water, or classic fly water, one sport for example that comes to mind right now between the main run at the ranger run and the clay bank. You have to adjust your fishing techniques for fly fishing, its a bit harder to pick pockets. One thing you can do is use a shorter tip and a longer leader like a T-8 tip that is 6 feet long and an 8 foot leader, with worm weights. You can use bass fishing worm weights to add extra weight to your fly's to just pick pockets, but it is a matter of your fishing style. A lot of guys would rather pass up pocket water that is easily fished with a float rig. I find especially in pocket water, with all the heavy current and different current directions you have problems with your leaders, sink tips getting pulled up or in different directions which pulls your fly up in the water column. So the worm weight principle works on the fact that you can use a longer tippet section and a heavier weighted fly to get down quicker, it uses your skagit line or floating spey line almost like a float.
