There are some good lakes up near northbend that are open yearround they are on wherehouser land I forget their names but they are up the same road as the N.Fork of the snoqualmie. I heard one of them produced an 8 pound cutthroat. If you don't want to go that far you could fish green lake. Work the shore with wolleys maybe do a little trolling. Maybe try chronimids if you see any surface action.
