sounds like you'll be there before the general season opener, but will have great water to fish anyway...
Lower Owens below Pleasant Valley Res
E Walker (Bridgeport)
The lakes will be both closed and frozen
Take a 4 or 5wt and you can nymph with smaller standard bugs (baetis, copper johns, assorted midges, pt's, etc)...you can fish streamers as well and there will be BWO hatches, maybe even caddis, depending on the weather.
edit....if you want to both throw dries and get warm, hike down into the Owens Gorge above PVR
