I'm far from an expert but I have fished Taney at night with decent success. For me bigger #6 to #10 streamers are the ticket. Wooly buggers and mohair leeches work well. Black, olive, and purple are good colors. Cast straight across stream or slightly downstream. Then do a strip type retrieve. Vary the speed and length of your strips. Usually the hits are hard! It is really exciting when the fish are hitting well.
You can fish with scuds and such at night. However you need to use some type of lighted indicator if you do that to see the takes. I've not ever tried this. The above technique has worked well and seems more fun to me.
Good luck.
