Cdock; the section right below the dam is hard to fish. I've tried and tried but had zero luck for the risers. They seem to delight in rising just beyond your farthest cast. There's really no sense in casting for them unless you see a fish rise a few times in the same spot. They're cruisers so blind casting is usually futile. I'm suprised to hear you caught a rainbow. In Barry Mitchell's book he says they were planted below the dam back in the mid 80's but didn't think they survived. How big was it?
I fold my vest patch in two and squeeze the fly inbetween, that usually soaks up a lot of the water. Then blow on it, re-apply Gink and false cast it a few times. Of course when a fish takes it again you may have to change flies.
When I fish I'd say 90% of the time I use the "hopper dropper" set-up. I usually use a size 10 or 12 Stimulator on top although you could use anything that floats reasonabally well (H&L, Bastard Adams, etc.) and lots of floatant on the fly and up the length of the leader. I use no more that about 24 inches of dropper tippet and use a bead head at least a hook size smaller than my dry. This set-up also gives the trout either a dry or a nymph to choose from and possibly a chance for you to hook two fish at once.
Exhumed, Slayer, Napalm Death and maybe a little touch of Saliva (click click boom) on the way there...Then into the 80's Hair Metal like Warrant, older Crue and Skid Row on the way back. Did you say Guano Apes Lone Fisher? Who the hell are they?
A little bit of clear nail poilsh will work on the fly line to leader connection to make it slide easily through the guides. I never use it, just something I read in a magazine before. I never mess with blood knots...they look too difficult to tie. Double surgeon's for lighter tippets, triple surgeon's for heavier tippets.
Since they're tighter and less baggy I would imagine neoprenes would hold less water. I've never gone all the way down while wearing them so I can't tell you for sure.
What does a small waterproof digital cost these days? I have a real nasty habit of dunking cameras and have lately been using disposable waterproof ones with generally poor results.
Don't forget the sun screen. Last time I wet waded the hot temperature as well as the glare off the water left me with an unbelievable sun burn. It was so bad I could hardly put on a pair of jeans for a couple of days after. Last time I ever did that. Now I prefer to sweat it out in my waders.
