I've been fly fishing for white bass on the Brazos River below Lake Whitney two times in December. The first time I had luck on a chartreuse/white Clouser and an olive woolly bugger. The second time they weren't that interested in either, although I did catch a fish on a Clouser tied by Bruce Mc that I received in the Christmas Fly Swap. I caught a few fish on a foam hopper, but when that died down, I tried a new fly I tied but had never fished. It is my take on a Matuka streamer, tied using chartreuse-dyed grizzly hackle I got in a $20 Whiting Farms Variety Pack/grab bag from Cabala's (a large bag full of various feathers in all the colors of the rainbow). Tied on a size 6 Gamakatsu B10S Stinger hook the fly measures 2-2.5 inches long. It is simply a dubbed body with two feathers for the tail and another wrapped around the hook shank to form a collar. This turned out to be the magic fly, as I caught 13 white bass in about an hour, compared to only six others the previous three hours. I really like the fly since it is super easy to tie and I am still a beginning tier. Plus, in that same variety pack I have the same feathers in blue, yellow, cream, orange and several other colors, so there is no shortage of variations of this fly that I can tie.
Also, here is video of that fishing trip. Just a word of warning, the video is long, but if you are bored and need something to watch, have at it. I am casting it on the new setup my brother got me for Christmas, a 6-6 3/4 wt Eagle Claw Featherlight fiberglass rod with a vintage Martin 63 "tuna can" reel. It is going to be a great small stream/tight quarters setup that cast great with 4.5 wt line (Cabala's Prestige Plus) once I got used to the parabolic action (it is quite a bit different from my fast action graphite rods).
