The following fishing report is from Yellow Dog Flyfishing:
*Flow Data: Yellowstone River near Livingston, MT
The stone is dropping fast with the cold weather but could be fishing in no time. Big stonefly nymphs, streamers, and maybe stonefly dries should work when the river clears. If you were to try, large dark stonefly nymphs will be the best option. Large dark colored streamers like an Ebony or Black Sex Dungeon will be another good option to fool fish in the dirty water.
