Here's a flashier version of the Black Bear GreenButt salmon fly, the Glitter Bear, designed by Bill Taylor of the Atlantic Salmon Federation. It is tied for both low and normal/high water. It has been my most effective pattern on the Miramichi during the summer months.
Tag: Oval silver tinsel (sized to suit hook size) and flourescent green/chartreuse floss. I am very partial to Gordon Griffiths floss.
Tail: Golden pheasant crest
Body: Peacock herl (I've been tying it with "peacock" ice dubbing loop dubbed as well)
Rib: oval silver tinsel (again, sized to suit hook size)
Throat: black hackle fibers (I usually use Whiting's hen neck for the throat, but lately have started using ringneck pheasant dyed black. It has a really neat greenish sheen to it that suits the fly very well)
Wing: 6-8 strands of your "flash du jour", over which is black bear, or, in my ties, black squirrel. (some day I'm going to figure out how to dye polar bear black and try that).
