I have fished both the LFZ and DSR this year, multiple times. The LFZ can be really crowded. But, both times I was there, I arrived mid-afternoon. There were a fair number of fishermen but they cleared out by 3 or 3:30. I was near the wire at the top end and shared that run with another fisherman 'til to got dark. Did OK on salmon and steelhead tho it was earlier in October before there were a lot of steelies in the river.
I fished DSR 4 times this year for a total of 8 days. It was not terribly crowded any of those times but I always go during the week. The salmon run early was a bust (as opposed to last year when it was simply awesome). However the steelhead this year have been as awesome as the salmon were last. In the four days I fished the DSR in mid- and late October, the two guys I fish with and I hooked somewhere in the neighborhood of 125-150 fish and brought probably 40-50 to hand/net. Most of these were in the 6-10 # category but each of us hooked and landed several that were quite a bit larger. I had one that was 14#, a really beautiful fish. These fish are fresh out of the lake, bright, and full of vim and vinegar. All were caught on an assortment of flies drifted on the bottom: BIG dark stoneflies, olive and black buggers, BIG (like size 6) BHPTs some with a bright green thorax and/or green bead, and small blue and green estaz eggs. (Now and again I'll pick one up on the swing at the end of a drift.)
I typically fish a tapered leader, maybe 9' down to 1x or so. Then a small swivel and tie a 2-3 ft. tippet to that, maybe 1, 2, or 3x depending on the water. I tie a small, say, 1.5", piece of heavy mono to the swivel to which I attach any split shot I'm going to use. My flies are generally weighted too. As others have said, there's no real beauty to any of this. The idea is to get the flies down to the fish and get a good drift into the holding water. I've found this to be between a heavy riffle at the head of a pool and the really flat water immediately below. Find the seams and edges. Not sure if this translates into the "transition" water seen in the various reports from Fat Nancy's, Whitakers, or DSR, but it's where I've hooked/caught probably 95% of my fish.
I'd love to go up this month but it's not looking favorable. Good luck when you do go.
