Dave I fished Lone Pine Lake last September and had great luck. I caught and released many 6-8" Golden Trout. Great time. I know that a Sept. trip won't help you with the conditions now but at least you know there are fish.
I didn't get a close up view but on 12/13 it appeared that it was iced over pretty good. If you enlarge the picture below you can get a glimpse from above.
