I imagine someone local will comment but I think your going to be pretty limited on options in the White's. I've skied there right around new years so I imagine the reservoirs are froze solid by Christmas.
I would check out Cliff Dwellers Lodge for the fishing report:

Both are very cool places to fish but I would go to the Ferry hands down if I was just looking for quantity. The river is a constant 48 degrees year round so it fishes well irregardless of the season.
